Read on to learn what matters when it comes to positioning, detection elements, and filter technology.", "fulltext": "In medical laser applications, the thermal effects on tissue can generate airborne particles, aerosols, and gaseous components. This raises a key question regarding laser smoke extraction in medicine: How can these emissions be captured as directly as possible at the point where they are generated? This is precisely where filter and extraction technology comes into play. It is not only the filtration performance that matters, but also the position of the capture element. The closer the capture point is to the source, the more effectively the contaminated air is directed into the filter and extraction system. What does a laser smoke extraction system capture? TBH filter and extraction systems capture the contaminated air during the laser procedure. This includes airborne particles, aerosols, and—depending on the application—gaseous components as well. The capture element is located close to the source. At the same time, when used as intended, it has no contact with the patient. Regulatory classification is also important: TBH does not market these systems as medical devices in this context. Instead, they serve as accessories for capturing and filtering the air generated during laser procedures. You can find more information about TBH’s solutions for medical and aesthetic laser applications on our Medical & Aesthetic Systems page. Why Extraction Is Important in Medical Laser Applications Laser treatments can produce a mixture of biological, cellular, and gaseous components. Therefore, the filtration and extraction technology should capture the contaminated air as close as possible to the source. For medical laser smoke extraction, TBH offers the Health Pro and Health Pro Silence filtration and extraction systems for medical and aesthetic laser applications. However, the right solution depends on the specific application. That’s why the following questions, among others, are important: Where is the laser smoke generated? How close can the extraction element be positioned? What particles and gaseous components are produced? How often and for how long does the laser application run? What are the requirements regarding noise levels and cleaning? This allows the filtration and extraction system to be tailored to the specific process. After all, it is not a single filter class that determines the appropriate solution, but rather the interplay of capture, airflow, and filtration technology. Talk to us about your laser application Do you use medical or aesthetic lasers and want to know how you can capture the contaminated air generated during operation as directly as possible?

Afterward, the surface is dry, precisely machined, and free of abrasive residues. This is precisely why many companies underestimate the second part of the process: emissions. That’s because during laser cleaning, the removed layer doesn’t simply vanish into thin air. Depending on the material, coating, and process parameters, smoke, vapors, gases, and fine and ultrafine particles are generated. The BGHM explicitly points out that cleaning and stripping with laser radiation can produce mixtures of hazardous substances, the composition of which depends on the substances being removed and the laser used. Especially with coatings, the composition is often not fully known. BGHM, 2024 This makes it clear: Laser cleaning is often a precise and modern process. However, it is not emission-free. Laser Cleaning Emissions: Why the Risk Is Often Underestimated In practice, the focus is often on the laser class, the safety zone, and safety goggles. This is correct. However, it is not sufficient. The DGUV identifies two key hazard areas for hand-held Class 4 laser devices used for cleaning and stripping: laser radiation and the hazardous substances generated during the processing. It also requires a functional, efficient extraction system; ablation byproducts should be captured as close as possible to the point of generation. DGUV FBHM-139, 2024 This is particularly important because the critical components are not always visible. Coarse smoke is noticeable, whereas ultrafine particles and gaseous components are not. Nevertheless, it is precisely these that can be relevant for inhalation exposure. What Studies on Particles and Gases Show The body of scientific evidence is growing. A study published in Environmental Research in 2024 examined airborne nanoparticles generated during laser cleaning of corroded 304L stainless steel surfaces. The study shows that laser cleaning can release nanoparticles and should therefore be included in a thorough exposure assessment. Park & Park, 2024 The French National Research and Safety Institute (INRS) also warns against the use of hand-held lasers for paint stripping, welding, and cutting. In laboratory tests on manual laser paint stripping of powder-coated steel, a high proportion of the fumes consisted of fine and ultrafine particles. In addition, INRS lists polycyclic aromatic hydrocarbons, isocyanates, ozone, benzene, and carbon monoxide, among others, as possible components of the emissions. INRS, 2026 Therefore, laser cleaning should not be categorically classified as “smoke-free” or “harmless to the air we breathe,” but rather evaluated on a process-by-process basis. Laser cleaning emissions depend on the material There is no single type of laser smoke. Corroded steel produces different emissions than stainless steel, painted components, plastics, oily residues, or multi-layer old coatings. Therefore, companies must take a closer look: What material is involved? Which coating is being removed? Are pigments, fillers, additives, old paint layers, or unknown residues involved? And how close is the operator working to the process zone? TRGS 528 specifies for thermal processes that material-specific, process-specific, as well as workplace- and task-specific factors must be included in the risk assessment. Among other things, it lists respirable dust, particles, and gases, as well as substance groups such as chromium(VI) compounds, nickel oxides, isocyanates, aldehydes, carbon monoxide, nitroso gases, and ozone. TRGS 528, 2020 For extraction systems, this means: The system must be tailored to the actual process, not just to the laser power. Source Capture Is More Effective Than General Ventilation When it comes to laser cleaning emissions, capture is key. The closer the extraction system is to the source, the less the hazardous substance spreads throughout the work area. TRGS 528 clearly states this principle: Hazardous substances should primarily be extracted at the source; the closer to the source, the more efficient the capture. TRGS 528, 2020 General room ventilation can be helpful. However, it is no substitute for effective source capture. The INRS notes that, for manual laser cleaning, general ventilation alone does not sufficiently control the chemical risk; fine particles, in particular, can quickly reach critical levels. INRS, 2026 Therefore, especially for hand-held applications, the combination of capture elements, airflow rate, airflow direction, filter technology, and work position is crucial. Filter Technology: It’s Not Just About Particles Many discussions revolve around HEPA or H filters. While this is understandable, it does not tell the whole story. This is because laser cleaning can generate not only particles but also gaseous components and vapors. Proper extraction systems therefore address several questions simultaneously: What particle sizes are present? Can hazardous gaseous substances be generated? Is the air recirculated or vented to the outside? How is filter condition monitored? And how does the facility demonstrate that the protective measures are effective? TRGS 528 requires an effectiveness assessment of protective measures, for example through workplace measurements or other suitable assessment methods. It also distinguishes between dust and gas measurements. TRGS 528, 2020 In short: Filter technology is not just an accessory. It is part of the protection concept. What Companies Should Specifically Check Now Anyone who uses or plans to use laser cleaning should not start by asking, “Which extraction unit is compatible with the laser?” A better approach is: “What emissions are generated by our process, and how do we safely capture them?” This primarily includes: Identifying materials and coatings Critically evaluating unknown existing coatings Incorporating material safety data sheets or analyses Plan extraction as close as possible to the source Consider particles and gases separately Verify and document the effectiveness of protective measures Train employees on laser radiation and hazardous substances The DGUV FBHM-139 provides practical guidance for assessing the risks of hand-held Class 4 lasers during cleaning and stripping. DGUV FBHM-139, 2024 Conclusion: Those who master laser cleaning also master the emissions Laser cleaning can make processes cleaner, more precise, and more efficient. That is precisely why it is worth taking a professional look at the emissions. After all, safety does not come from assuming that a small amount of visible smoke means a low risk. It comes from assessment, source identification, appropriate filtration technology, and verifiable effectiveness. That is the difference between “laser cleaning works” and “laser cleaning is mastered.” Sources DGUV: FBHM-139 Laser Work, Cleaning, and Stripping with Laser Radiation, 2024 BGHM: Cleaning and Stripping with Laser Radiation—But Safely, 2024 BAuA/AGS: TRGS 528 Welding Operations, 2020 INRS: Warning Regarding Hand-Held Lasers, 2026 Park, H. & Park, C.: Airborne Nanoparticles During Laser Cleaning, Environmental Research, 2024" }, { "title": "Energy-Efficient Exhaust System: Saving Energy Through Targeted Collection", "url": "https://www.tbh.eu/en/blog/energy-efficient-exhaust-system-saving-energy-through-targeted-collection/", "type": "blog", "last_modified": "2026-09-29", "summary": "An energy-efficient extraction system is not necessarily the one with the highest airflow or the lowest power consumption.

What matters is where pollutants are captured, how much air is actually needed for that purpose, and what happens to the purified process air afterward. In the case of laser fumes, welding fumes, soldering fumes, fine dust, or aerosols, pollutants are usually generated directly at the process site. If these particles are extracted close to the source, significantly less room air needs to be moved. This supports occupational safety and can simultaneously reduce energy consumption. This is because any volume of air that is unnecessarily extracted must be mechanically moved, filtered, and, depending on the airflow path, replaced. This is particularly relevant in heated or air-conditioned production areas: If purified air—which has previously been heated or cooled—is vented to the outside, it draws additional energy from the room. This air must be replaced with fresh air and then reheated or recooled. Therefore, the rule is: Extract as little air as possible, but as precisely as necessary—ideally right where particles, smoke, or vapors are generated. Energy-Efficient Exhaust System: More Air Isn’t Necessarily Better In practice, energy efficiency in exhaust systems is often associated with motor power or energy efficiency ratings. This view is too narrow. A high airflow rate can be useful if the process requires it. However, it can also consume unnecessary energy if contaminants aren’t captured in a targeted manner. If contaminated air is extracted only after it has spread throughout the room, significantly higher air volumes are required. At the same time, the risk increases that employees will come into contact with hazardous substances before they are captured. A well-designed extraction solution therefore does not move “as much air as possible,” but rather provides the appropriate airflow for the specific process. What matters here is the effective airflow. Filters, hoses, extraction arms, and ductwork create resistance. Therefore, it is not just a theoretical maximum value that counts, but the airflow that is actually available at the workstation. The free-flow airflow is measured without resistance, while the effective airflow is determined only after factoring in filters, hoses, extraction arms, and other components. EC Motors and Demand-Based Performance Efficient motor technology is another key component. Brushless EC motors enable electronic speed control and can thus be adapted to actual demand. This is particularly relevant because not every process requires maximum extraction capacity at all times. However, an efficient motor alone does not make for an energy-efficient extraction system. It is the interplay of proper air intake, a suitable filter concept, a correctly designed airflow rate, and sensible airflow guidance that determines the energy balance. With EC motors—that is, electronically commutated, brushless motors—the speed can be adjusted via electronic control, enabling performance to be tailored to actual needs. Energy-Efficient Exhaust System and Air Recirculation If purified process air can be recirculated back into the workspace, this can offer energy benefits. The already temperature-controlled room air remains inside the building instead of being vented outside as exhaust air. As a result, less outside air needs to be brought in, heated, or cooled. Process air is typically recirculated back into the workspace or, in the case of particularly critical processes or materials, vented outside. The advantage of recirculated process air is that the conditioned air remains in the room, thereby saving on heating costs. Nevertheless, air recirculation is not always the right solution. In the case of hazardous substances, unclear risk assessments, or insufficiently verified separation efficiency, exhausting the air may be necessary. In such cases, the protection of employees takes precedence over energy savings. Occupational safety takes precedence over energy efficiency An energy-efficient exhaust system must never mean that airflow capacity is reduced in the wrong place. When dealing with hazardous substances, welding fumes, laser fumes, soldering fumes, or health-hazardous dusts, safe capture and filtration are the top priorities. Therefore, the best solution is not necessarily the one with the lowest power consumption at any cost. A filtration and extraction system is efficient when it reliably captures pollutants, avoids unnecessary airflow, and designs the airflow to suit the process. Especially with hazardous substances, capture at the source is a key technical protective measure. Many technical regulations and standards prioritize technical protective measures in the following order: prevention, process-based extraction, ventilation measures, and personal protective equipment. Conclusion: An energy-efficient extraction system starts with planning Saving energy with extraction systems begins with proper planning. Capturing pollutants close to the source, an air flow rate tailored to demand, efficient EC motors, and a professionally evaluated decision between recirculation and exhaust ventilation can improve the energy balance. At the same time, one thing remains clear: If exhaust ventilation is required for occupational safety reasons, the protection of employees takes priority. An energy-efficient extraction system does not simply move as much air as possible; rather, it captures pollutants in a targeted manner—safely, according to demand, and as close as possible to the source.

Read on to learn why extraction, airflow, and filtration technology must work together.", "fulltext": "An industrial laser fume extraction system affects more than just the air in the workplace. This is because marking, engraving, cutting, or welding—depending on the material—generates fumes, fine particles, and gaseous components. If these emissions remain in the processing area, they can accumulate there and damage sensitive components. Optics are particularly sensitive. Deposits on a lens can impair the conditions for stable machining and result in additional cleaning or maintenance efforts. That is why it is worth considering extraction as early as the planning stage of a laser system—and not only once the first deposits become visible. Industrial laser fume extraction begins with capture High-performance filtration technology is only effective if the emissions actually reach the filter and extraction system. That is why the position of the capture point and the airflow within the processing chamber play a crucial role. Material, process parameters, enclosure, duct routing, and operating duration all influence how laser fumes spread and what extraction capacity is required. Especially with automated systems, the extraction technology must also interact reliably with the production process. You can find more information on the various influencing factors and suitable systems in our Laser Fumes Solutions section. Fewer Deposits in the Machine Enclosure Fine particles can settle not only on the lens but also on other surfaces and components inside the machine. Capturing fumes as directly as possible reduces their entry into the area surrounding the processing site. As a result, the extraction system can help minimize cleaning efforts and protect sensitive machine areas from unnecessary deposits. TBH offers modular filter and extraction systems for this purpose, whose configuration can be adapted to different laser processes. The LN200 series, for example, is suitable for applications with higher flow resistance, longer extraction paths, or smaller pipe diameters. Depending on the configuration, various pre-filters, particle filters, and activated carbon filters can be combined. Integrating Process Quality and Occupational Safety Emissions that spread throughout the machine room can also enter the work environment if they are not adequately captured. Therefore, the design should take into account not only the machine but also the potential exposure of employees. For relevant applications, TBH offers configurations tested in accordance with EN ISO 21904. The appropriate system design always depends on the specific process, the substances generated and the intended operating conditions. Extraction and filtration should therefore be selected as part of the overall process concept rather than on the basis of a single filter specification. A suitable industrial laser fume extraction system is therefore not achieved simply by selecting a single filter. Capture, airflow path, filter configuration, and system performance must all be properly matched. Consider Laser Extraction Systems Already During System Planning Those who only consider the extraction system after commissioning may have to retroactively adjust capture positions, duct routes, or system performance. If, on the other hand, it is planned together with the laser process, enclosure, and automation, the individual components can be coordinated with one another from the very beginning. This is exactly what we’d like to discuss at the 35th BI-MU. The international trade fair for machine tools, robotics, automation, and digital and additive manufacturing will take place from October 13–16, 2026, at fieramilano Rho.

While these specifications are important, they do not answer the most critical question. The first crucial factor is whether you are properly capturing the laser fumes so that fumes, fine dust, and vapors can reliably enter the filter and extraction system in the first place. Anything that flows past the capture point cannot be separated by a filter later on. Capturing Laser Fumes Properly: Why the Source Is Crucial During laser processing, emissions are generated directly at the workpiece, in the processing zone, at a machine opening, or inside an enclosure. It is precisely there that the contaminated process air must be captured as effectively as possible before it spreads throughout the work area. When purchasing a laser smoke extraction system, this means: The right system isn’t determined by which filter is the most powerful, but by how emissions are generated and directed in the actual process. A high separation efficiency is only relevant for the portion of pollutants that actually reaches the filtration system. Therefore, operators should determine whether an extraction arm, a fixed capture point, an enclosure, or a machine connection is suitable for the application. Flexible manual workstations require different solutions than automated laser cells. Those who would also like to know which filter stages are relevant afterward can find the classification in the article \"Which filters are suitable for laser fume extraction?\". Distance, Air Path, and Practicality A common weak point is the distance between the emission source and the capture element. If an extraction arm is positioned too far away or is not consistently positioned during daily operations, the capture efficiency decreases. Cross-drafts, thermal currents, compressed air, operator movements, or machine movements can also influence whether the contaminated air actually flows toward the extraction system or disperses throughout the room. In addition, the airflow path determines the system’s effectiveness. Hoses, pipes, elbows, adapters, or machine connections cause pressure losses. Therefore, simply looking at a system’s maximum airflow rate is not sufficient. What matters for selection is the actual airflow available at the capture point in the real-world setup. Especially with longer hose runs, narrow cross-sections, or retrofitted machine integration, the capture performance should be thoroughly tested. When You Should Check Laser Fume Capture An individual assessment is recommended if odors or visible smoke occur despite the extraction system being operational, if extraction arms frequently need to be repositioned, or if the extraction system was retrofitted to an existing laser process. Capture should also not be designed on a one-size-fits-all basis when dealing with changing materials, varying workpiece geometries, or sensitive environments. Effective laser smoke extraction begins where the smoke is generated. Only when you properly capture laser smoke can you meaningfully evaluate filter specifications, air recirculation, maintenance, and operating costs. To learn how particle size, particle volume, and process parameters play a role in this, read the article “Particle Size in Laser Smoke: Why the Process Matters.” The TBH team is here to help you tailor the extraction and airflow to your specific process." }, { "title": "Which filters are suitable for laser fume extraction?", "url": "https://www.tbh.eu/en/blog/which-filters-are-suitable-for-laser-fume-extraction/", "type": "blog", "last_modified": "2026-09-09", "summary": "The right filter for laser fumes depends not only on filter class, but also on particles, capture, airflow and the specific process.", "fulltext": "When choosing a laser fume extraction system, people often ask about the right filter first. This is understandable, since filter configuration, separation efficiency, and service life all affect occupational safety, maintenance, and operating costs. Nevertheless, a filter for laser fume extraction cannot be determined simply by a single filter class. The key factors are which substances are generated during the process, how effectively they are captured, and which filter combination is best suited to the specific application. What function must the filter fulfill? A filtration and extraction system passes contaminated process air through several filter elements that are tailored to the specific application. Depending on the process, pre-filters, particulate filters, and—in the case of gaseous components or odors—activated carbon filters are used. Prefilters reduce the load on downstream filter stages; particle filters remove fine particles; and activated carbon may be relevant for certain gaseous substances. The appropriate combination depends on the material, the emission volume, the particle size, and the airflow. This is precisely why the filter should not be considered in isolation. If extraction at the source is ineffective, only a portion of the pollutants will reach the filtration system. The filter may be technically suitable, yet its effectiveness in the workplace remains limited. The basis for this is described in the article “Properly Detecting Laser Fumes,” which explains why extraction should be addressed before selecting a filter. Why Filter Service Life Is Not a Fixed Product Specification Many operators want to know how long a filter will last before making a purchase. However, a reliable answer is only possible if the process is known. Material, laser power, pulsing, processing duration, particle load, extraction design, airflow, and filter combination all influence service life. Even effective extraction can result in more particles reaching the filter. This is not automatically a disadvantage; rather, it may indicate that fewer emissions are entering the work area uncontrolled. When making a purchase, therefore, the decisive factor is not how long a filter for laser fume extraction generally lasts. What is more important is determining what filter service life is realistic for your specific process and how maintenance, replacement filters, disposal, and system availability can be sensibly planned. Especially in cases of higher particle loads, sticky residues, or gaseous components, the filter system should be designed specifically for the application. What Matters When Purchasing A suitable filter solution takes into account particles and potential gaseous components, as well as maintenance and integration. Operators should clarify whether air recirculation is planned, what substances are generated during the process, whether there are specific occupational safety or environmental requirements, and how frequently filter changes are realistically feasible in day-to-day production. Standards, dust classes, or certifications should only be used as selection criteria if they are appropriate for the specific process and the chosen system. The best filter system results from a combination of process understanding, capture efficiency, and airflow management. To learn which particles can be generated during laser processes and why size, number, and material are key factors in the design, read the article “Particle Size in Laser Fumes: Why the Process Matters.” If you’d like to evaluate a filter for laser fume extraction for your application, the TBH team can assist you in selecting the appropriate filter configuration, maintenance plan, and airflow design.

He focuses on filter technology, quiet operation, and practical application in daily practice.", "fulltext": "Dr. Helmut Hahn is a dermatologist and partner at the Berchtesgaden Skin & Laser Center, and has been using a TBH extraction system for years. In this article, he discusses the requirements he believes modern extraction systems must meet for laser treatments and shares his experiences with them in daily practice. Extraction is part of the treatment concept Dr. Hahn does not view extraction during laser treatment as an add-on, but rather as an integral part of the setup. In addition to the laser itself, he mentions cooling and a suitable extraction system. He says: “A man needs three things: good laser equipment, of course, but also cooling, and above all, an extraction system that meets modern requirements.” He also describes how various laser procedures generate smoke gases, particles, and aerosols. In a medical setting, therefore, capture at the source, a suitable filter system, and practical usability play an important role. TBH offers systems for medical practices and operating rooms that include, among other features, InLine filters, H14 particle filters, and activated carbon filters. Key Requirements in Everyday Practice Dr. Hahn lists several requirements for use in medical practice. The devices should integrate well into the workflow. They should operate quietly and be easy to use. In doing so, he highlights the points that are crucial for many users: high practicality for daily use, suitable filter technology, and operation that does not unnecessarily disrupt treatments. The TBH Health Pro Silence is designed for continuous operation in medical practices and operating rooms, is low-noise, and features a filter configuration comprising an H14 particle filter, an activated carbon filter, and an InLine filter. Customer testimonial from Freilassing Dr. Hahn points out that when investing in laser technology, savings are often made elsewhere. He says: “Then it’s no longer enough in the end: and savings are made in the wrong place.” In this context, he mentions not only the performance of the devices but also pre-filters, device size, and integration into daily practice. His pointed concluding statement is: “What good is the best Michelin-starred chef if your restaurant reeks of grease? No paying guest would accept that and would eventually stop coming.” Conclusion Dr. Hahn’s statements clearly highlight three points: Extraction is part of the treatment concept for laser procedures, the filter system must be suited to the application, and the solution must be reliable for use in daily practice.

But what does the 6th CMRD revision actually mean for employers and employees?", "fulltext": "Why should companies in the US, Canada and Australia care about an EU directive on welding fumes? Because the core issue is not European. It is occupational exposure. The EU’s proposed update matters directly to companies operating in Europe. But even for manufacturers, distributors and production sites outside the EU, the underlying message is the same: welding fumes are a well-established health risk, and regulators across major industrial markets already expect employers to assess exposure and control it properly. In the United States, OSHA requires local exhaust or general ventilation to keep toxic fumes, gases and dust below permissible levels. In Canada, CCOHS and federal guidance clearly describe welding fumes as a complex and potentially carcinogenic mixture and emphasize local exhaust ventilation close to the source. In Australia, Safe Work Australia has already moved to a significantly lower workplace exposure standard for total welding fumes, reducing it from 5 mg/m3 to 1 mg/m3 in jurisdictions that have implemented the change. What exactly is changing in the EU? The short version: welding fumes are being brought more explicitly into the scope of the EU’s Carcinogens, Mutagens and Reprotoxic Substances Directive, the CMRD. On July 18, 2025, the European Commission presented its proposal for the 6th revision of the CMRD. The proposal explicitly addresses welding fumes. The Council of the European Union adopted its position on December 1, 2025, and the relevant European Parliament committee adopted its position on April 15, 2026. As of April 29, 2026, the revision has not yet been finally adopted, but the direction is already clear. Once formally adopted, member states are expected to have two years to transpose the changes into national law. Why is the EU making this change? Because the health risks have been known for years, and regulators are moving toward clearer, more enforceable protection. Welding fumes are not a single substance. They are a complex mixture that can include hazardous components such as chromium, nickel, cadmium and manganese, depending on the material and process. That is one reason they have long been difficult to handle consistently in practice. The scientific and regulatory direction is clear. The UK HSE (Health, Safety and Environment) states it very plainly: all welding fume can cause lung cancer. OSHA points to hazards including lung cancer, metal fume fever and neurological concerns related to manganese exposure. Canadian guidance describes welding fumes as very fine particles, often below 1 µm, capable of reaching deep into the lungs. How many workers are affected? More than many companies assume. According to the European Commission’s staff working document, around 1.2 million workers in the EU are exposed to welding fumes. About three quarters of them work in four sectors: specialized construction activities, building construction, manufacture of metal products, and motor vehicle trade and repair. The wider context is just as important. The European Parliament states that around 120,000 workers in the EU are diagnosed with occupational cancer each year following exposure to carcinogens at work, and around 80,000 die annually from those cancers. How many people could be better protected by the new rules? The EU does not present that as a single headcount. Instead, it describes the expected long-term health benefit of the package. According to the European Commission and the European Parliament, the 6th CMRD revision could prevent around 1,700 lung cancer cases and around 19,000 other diseases over a 40-year period. It is also expected to reduce healthcare costs by up to EUR 1.16 billion. These figures refer to the overall package, not welding fumes alone. Still, welding fumes are clearly part of that protection agenda. What does this change mean for employers in practical terms? It means welding fume exposure will become even harder to treat as a secondary issue. For EU employers, the upcoming change points toward stronger expectations around risk assessment, exposure reduction and technical control measures. For companies outside the EU, the practical message is very similar, because regulators in other regions already expect this kind of action. OSHA requires ventilation to control exposure. Canadian guidance says local exhaust ventilation should be positioned close to the plume source and makes clear that respirators should not replace mechanical ventilation. Safe Work Australia says exposure standards are not a safe target in themselves and that employers must take all reasonably practicable steps to eliminate or minimize risk, not merely stay below the numerical limit. When is the new EU rule expected to take effect? As of April 29, 2026, the revision has not yet completed the legislative process. The next steps include Parliament’s plenary stage and negotiations with the Council on the final legal text. Only after formal adoption will the transposition period begin. The important point is this: the legislative process is still moving, but the compliance direction is already visible. And once adopted, EU member states are expected to have two years to implement it in national legislation. Why should employers and workers act now instead of waiting? Because the health risk already exists. The regulation is simply making it harder to ignore. Risk assessments, workplace measurements, equipment upgrades and properly designed extraction solutions take time. Companies that wait for the final legal deadline may leave themselves with too little room to plan, budget and implement effective controls. The more complex the production environment, the more important early action becomes. And there is another reason. This is not a new hazard. It is an already recognized hazard that is receiving stronger regulatory attention. Acting now is not only about compliance readiness. It is about protecting people under current operating conditions. What happens if companies do not invest in effective fume extraction? Then they continue to carry a health, operational and compliance risk that is increasingly difficult to justify. Health effects linked to welding fume exposure include acute irritation, metal fume fever, asthma, chronic lung disease and an increased risk of cancer. OSHA also points to hazards from toxic metals and gases, while Canadian and Australian guidance emphasize the need to identify hazardous components, monitor exposure where necessary and control the plume before it reaches the worker’s breathing zone. In short: not investing does not remove the risk. It simply leaves the exposure in place. What does all of this have to do with our extraction systems? Everything. If regulators in Europe, the US, Canada and Australia all point in the same direction, the practical takeaway is straightforward: welding fumes need to be captured as close as possible to the source, filtered effectively and managed through a solution that fits the real process. That is exactly where professional extraction and filtration systems come in. Conclusion The EU revision is not final yet. But the message is already clear. Welding fumes are receiving stronger regulatory attention in Europe, and the same issue is already highly relevant in North America and Australia. The science is established. The risk is real. And the expectation is moving in one direction: assess exposure properly, control it effectively and do not treat extraction as an optional add-on. For employers, that means now is the right time to review current welding applications and existing controls. For workers, it means better recognition of a risk that has too often been normalized. And for extraction technology, it means a more visible role in what it should always be: a core part of occupational health protection.

Nevertheless, laser processing can generate very fine and ultrafine particles that are relevant to occupational safety, filter selection, and plant design. Among other things, the particle size of laser fumes influences how long particles remain in the air, how deep they can penetrate the respiratory tract, and what requirements arise for collection, airflow, and filtration technology. Why Particle Size in Laser Fumes Is Important Laser processes can generate particles in the µm and nm ranges. The smaller these particles are, the longer they can remain suspended in the air and the more difficult they are to assess with the naked eye. Visible fumes therefore reveal only a portion of the exposure. Fine and ultrafine particles can still be a concern even when the workplace appears visually clean. For operators, this means that a laser smoke extraction system should not be evaluated solely based on whether smoke is visible. What is more important is whether the process air is captured directly at the source, directed in a controlled manner to the filtration and extraction system, and properly filtered there. The article “Properly Detecting Laser Smoke” explains how this capture process works from a technical perspective. The Process Determines the Pollution Level Material, coating, laser power, pulsing, processing speed, cutting depth, and workpiece geometry all influence which particles are generated and in what quantities they are released. The process environment also plays a role. Open-air processing distributes emissions differently than a closed enclosure. Changing materials lead to different requirements than a stable production run with consistent parameters. For this reason, it is not possible to make reliable generalizations about particle load and filter service life. Two laser applications may appear similar on paper, but in practice they can produce different emission levels, particle sizes, and gaseous components. Anyone selecting a filtration and extraction system should therefore describe the process not only in terms of the machine, but also in terms of the material, emission source, airflow, and duration of use. Implications for the Exhaust System The particle size of laser fumes influences how an exhaust system should be designed. Fine particles must be reliably captured, directed to the filtration system, and separated there using appropriate filter stages. If vapors, odors, or gaseous components are also present, a different filter combination may be required than for pure particle emissions. The article \"Which filters are suitable for laser fume extraction?\". categorizes which filters are suitable for this purpose. A well-founded design therefore begins with the process itself. Visual inspection alone is not sufficient if fine or ultrafine particles can be generated. When selecting a filtration and extraction system, TBH considers factors such as material, particle generation, capture efficiency, airflow path, filter configuration, and maintenance concept.

In the video, he explains why workers’ compensation insurance associations require the use of extraction systems to protect against airborne particles generated during procedures. Themes Hazards in Dermatology Clinics Why is smoke evacuation essential during laser treatment? Whether you use ablative, vaporizing, or Q-switched lasers, human particles are released into the air via nano- or picosecond pulses. Even when you use conventional methods such as an Erbotome or a soldering iron to burn tissue, smoke is produced, and human tissue—often contaminated with viral genomes—is atomized into the air, where it can be inhaled. How harmful is surgical smoke? Surgical smoke is just as harmful as cigarette smoke. The ablation of 1 gram of tissue produces smoke whose mutagenicity is equivalent to that of 6 unfiltered cigarettes. When using monopolar diathermy in a plastic surgery room, the daily smoke production is equivalent to that of approximately 27–30 cigarettes. Therefore, the Control of Substances Hazardous to Health Regulations (COSHH) in the UK, the Berufsgenossenschaft für Gesundheitsdienst und Wohlfahrtspflege in Germany, and the Occupational Safety and Health Administration in the US recommend the use of smoke evacuators.

In this matter, you have a dual obligation, including a duty to your patients. Consumer protection laws require that you ensure the highest possible level of patient safety to guarantee that the patient does not suffer any harm as a result of your treatment. Harm can result not only from medical malpractice, such as improper laser treatment, but also if the patient inhales or absorbs substances that may be carcinogenic or infectious. Therefore, it is of the utmost importance that you exercise the utmost care. What are the requirements of the workers' compensation association? The workers’ compensation association is showing increased interest in ensuring workplace safety and health protection. As the practice operator, you are obligated to protect both your employees and yourself by preventing the inhalation of HPV viruses, which can lead to laryngeal papillomas or laryngeal cancer over the long term. Therefore, it is now essential to use a suction device. BG Guidance on Risk Assessment in Medical Practices As a doctor, the safety of patients and staff is essential. The risk assessment required by the Occupational Safety and Health Act helps identify risks and implement protective measures to prevent health hazards and accidents. This boosts staff motivation and performance, as well as the quality of your practice. Documentation provides legal certainty. For guidance and support, visit Risk Assessment in Medical Practices (bgw-online.de) An excerpt from the BG Risk Assessment brochure states: “High-Frequency SURGERY or Lasers: During HF or laser surgery, there may be increased contamination of the indoor air due to vaporized or burned body tissue as well as evaporating disinfectants. The fumes may contain infectious pathogens. Protection goal: Avoid inhaling fumes and vapors generated during the use of HF surgical devices and lasers. T-O-P Measures (Selection) Technical: • Procure and set up equipment that complies with safety standards • Use equipment with fume extraction • Have equipment maintained by experts every two years Organizational: • Ensure adequate ventilation Personal: • Train employees • Wear appropriate protective equipment: – Insulating gloves – Safety goggles – Type P2 respirator Occupational HPV Exposure: Case Studies Highlight Risks for Healthcare Workers A 44-year-old surgeon who had treated anogenital condylomas and cancerous lesions with an Nd:YAG laser for many years was diagnosed with laryngeal papillomatosis caused by HPV types 6 and 11, with no other known sources of HPV exposure aside from his occupational exposure. A 28-year-old surgical nurse developed recurrent laryngeal papillomatosis due to an HPV infection, recognized as an occupational disease, after repeatedly assisting in CO2 laser and electrocautery surgeries for anogenital condylomas. A 62-year-old gynecologist with HPV-16-positive oropharyngeal carcinoma had over 30 years of experience in the removal of cervical and vulvar lesions using CO2 laser and LEEP and had no other risk factors. The same study described a 53-year-old gynecologist with HPV-16-positive tonsillar carcinoma who had performed laser ablations and LEEPs for over 20 years without adequate ventilation or protective measures, with no other risk factors identified. HPV DNA has been detected multiple times in laser smoke during the removal of papillomas and condylomas; however, its infectivity has not yet been conclusively proven. The exposure risk for medical personnel is low when protective measures are followed; however, in the gynecological field, it is significantly higher than in the ENT field due to the larger volume of tissue to be removed.

All occupational safety guidelines, such as TRBA 250, DGUV Rule 109-002, and those issued by the professional associations, primarily require an exhaust system and, as a supplement, PPE (personal protective equipment).Only an exhaust system with HEPA filters certified to meet the filtration efficiency standards of EN 1822 guarantees optimal protection for patients, medical staff, and physicians. Why is proper suction important during laser treatments? Laser treatment of virus-infected tissue can lead to the release of respirable aerosols containing infectious particles such as viruses or their genomes. Temperatures are lower at the edge of the ablation crater; a sterilizing effect is achieved only at high temperatures. If large fragments of virus-infected cells are torn from the tissue, intact viruses may be present in the aerosol, e.g., HPV in warts, condylomas, and papillomas, or adenoviruses in tear fluid during ophthalmic surgeries.To minimize risk, thermal vaporization techniques, e.g., using an Nd:YAG laser, should be preferred for such treatments. Plastics used during treatment can catch fire. PVC produces hazardous gases such as HCl. If these come into contact with mucous membranes, the resulting hydrochloric acid can cause tissue burns, and if inhaled, can lead to alveolar collapse. Technical safety measures, such as standard-compliant laser equipment, proper extraction of combustion products, the use of activated carbon or HEPA filters, and the safe handling of chemicals, are essential to protect staff and ensure safety.Source: FA Info_005_Lasers in Medicine_151109 (bgetem.de) What particles or emissions are produced during laser hair removal? Exposure during laser treatment involves a mixture of biological, cellular particles, which may also be in gaseous or vapor form. In addition to papillomaviruses and multidrug-resistant pathogens, researchers have also detected benzene, toluene, and xylene, hydrogen cyanide (prussic acid), formaldehyde, acetaldehyde, acrolein, cresols, and phenol in laser smoke. Depending on the energy input, the particles can be larger than 200 micrometers or smaller than 10 nanometers. The combustion of the cooling agent sprayed onto the skin during laser hair removal produces highly toxic vapors. The patented InLine filter, a pre-filter in the collection element, ensures high protection against these dangerous particles.Source: Eickmann U, Falcy M, Fokuhl I, Rüegger M, Bloch M, Merz B. Surgical Fumes: Hazards and Protective Measures. Edited by: International Section of the ISSA for the Prevention of Occupational Accidents and Diseases in the Health Sector. 2011 What is important for accurate data entry? The collection component of a filtration and extraction system must be tailored to the process. An InLine filter located within the collection system acts as a pre-filter, capturing the coarsest particles directly at the source, thereby preventing them from entering the extraction arm and reaching the filters in the system. This minimizes the cleaning effort. The effectiveness of the TBH hygiene concept for the residue-free removal of contaminants in the system has been tested and confirmed by the accredited testing laboratory CleanControlling Medical GmbH & Co. KG in Emmingen-Liptingen. The system, including all accessories, can be effectively cleaned in just a few simple steps. The InLine filter should be replaced daily depending on usage, but at least once a week. Video: TBH Health Series – Cleaning Instructions on YouTube Applications For a safe extraction Aerosol/ Dental Any treatment in a dental practice creates high aerosol concentrations. Oral suction only eliminates coarse particles. A valuable device for reducing the aerosol risk in the practice is the professional, filtering extraction system by TBH. Removing lesions with a laser To prevent the inhalation of potentially infectious particles during the laser removal of benign, melanocytic dermatological lesions, these particles must be suctioned away. Gynecology In addition to water vapor, surgical smoke contains harmful substances. When coloring agents such as acetic acid or iodine are used to prepare the surgical site during gynecological procedures, carcinogenic acetamide can form, which can accumulate in the pulmonary alveoli. Stories by two customers Prof. Nikolai AttardBChD., MSc. (Prosthodontics), PhD (TO) (Head, Department of Oral Rehabilitation and Community Care Faculty of Dental Surgery, University of Malta) “The COVID-19 pandemic has brought many changes to our daily operations at the Faculty of Dental Surgery, University of Malta. From the onset of the pandemic in March 2020, the Faculty administration embarked on reorganizing our clinic protocols in preparation when we would start clinical sessions with our students. One of our main concerns was how to reduce potential exposure risks for our students, who are at various levels of training. Following discussions and guidance from Health authorities, the faculty introduced the TBH extra-oral extraction systems to be used for all aerosol-generating procedures. The aim was to capture at source any residual aerosol emanating from dental procedures. We have found the units to be very effective on various levels- the units are very powerful, yet without generating excessive noise. Indeed a high-speed hand piece generates more noise than the TBH units do. They are also very simple to operate. Another benefit we observed in clinics was that the unit has helped students maintain proper posture during the dental procedures since the TBH unit precludes them from engaging in bad posture. Patients, of all ages do not mind the unit on them and some have actually remarked that it made them feel more secure. The dental nurses feel that the units do not just offer safety to the students and patients but also to themselves, as extended members to the dental team. The units require little maintenance, and are easy to clean after every patient. Weekly, the filters in the unit get replaced to ensure maximum efficiency. To conclude we are very happy with the TBH units and highly recommend them in the dental clinic“. Dr. Marco DegidiDentist \"I believe the pandemic has made us realize how important it is to use all possible tools to improve air quality in dental offices, in order to protect ourselves, our staff and our patients. The use of TBH extraction systems is a key step in this direction and we are successfully using them in all seven of our operating rooms.\" Dr. med. Helmut Hahn Dermatologist, partner at the Berchtesgaden Skin & Laser Center, and conference chair of the DDL Congress As an experienced specialist in laser medicine, I always recommend purchasing high-quality laser equipment, an efficient cooling system, and, in particular, a modern fume extraction system to meet current safety standards. People often try to cut costs, especially when it comes to exhaust systems—a serious mistake, since the fumes released during laser operation are not only unpleasant but also harmful to health. They contain carcinogenic and infectious particles, including HPV viruses, which, if inhaled, can cause laryngeal papilloma or laryngeal carcinoma. The use of an adequate extraction system with HEPA H-14 filters is therefore essential to protect both patients and staff from these risks. In my practice, this investment has not only significantly improved air quality but has also led to a noticeably lower rate of sick leave among the team, underscoring the necessity of effective protective measures.

Fine dust filters, also known as HEPA filters (High Efficiency Particulate Air), are highly efficient air purification systems. They play an important role in improving air quality by removing tiny particles, aerosols and toxic dusts from the air. In addition, particulate filters provide important health protection. Classification and standards of particulate air filters Particulate air filters are classified according to ISO 16890-1:2016, based on particle size. The following categories are distinguished: - ISO Coarse: Retention capacity against ISO A2 dust - ISO PM10: Particles ≤ 10 μm - ISO PM2.5: Particles ≤ 2.5 μm - ISO PM1: Particles ≤ 1 μm In addition, HEPA Class H13 and H14 filters are the highest HEPA class and are used to collect industrial particulate matter. Effective separation with particulate air filters High-quality particulate filters, especially HEPA filters, consist of a complex network of fibers. They have the following characteristics: Over 1000 layers of cellulose and synthetic materials Filtration efficiency of > 99.9% for particles between 0.1 and 0.3 µm Fewer than 3 particles in 10,000 pass through the filter However, regular replacement of particulate filters is essential for optimal performance and hygiene. The EN 1822-1:2009 standard classifies particulate filters into EPA (E10-E12), HEPA (H13-H14), and ULPA (U15-U17). As a result, regular change intervals prevent the formation of germs and bacteria that can occur when high concentrations of pollutants are present in saturated filters. In the USA, on the other hand, HEPA has a fixed filtration efficiency and is comparable to filter class H13 according to EN 1822-1. Protective measures and use of particulate air filters In dusty environments, particulate filters are part of a comprehensive approach to protection: This includes: Dust avoidance at the source Direct extraction at the point of emission Use of efficient ventilation systems with fine dust filters Use of personal protective equipment In addition, modern dust collection systems with particulate filters have warning systems that sound an alarm when filter performance drops, thus ensuring continuous protection of workers.

Working on machines and systems involves different potential risks, depending on the processing material and the process itself. These risks should be kept as low as possible. Certain standards and guidelines define safety precautions, which have to be adhered to in order to work without hesitation. This text provides an overview of the directives and guidelines mentioned on our site, each with a brief explanation. It merely serves as information about the most relevant standards for clean air and safety at work. In order to be able to assess the hazard potential, the RL 2014/34/EU and TRGS 720 - TRGS 724 categorize hazardous areas correctly. Labels ensure that products in potentially explosive atmospheres are conform to the conditions for a safe workplace. Equipment and components cannot contain any material, which could cause explosions or release contaminants directly into the environment. Release or processing of individual particles can trigger a dangerous reaction. DIN EN 1127-1:2011-10 defines suitable planning and production measures to achieve the required safety. The RL2006/42/EC (2023/1230, starting January 20, 2027) and DIN EN 60204-1:2026-06 (VDE 0113-1:2026-06) define appropriate measures to protect the workers from electric shock by electrically powered devices. In this context, DIN EN 61340-5-1 specifies the basic requirements for handling ESD. Depending on the work environment, e.g. the work shoes have to be antistatic with a heat or cold resistant sole. The legal examinations prescribed by law for repeat tests for measuring and control devices in laboratories are carried out after repair and modifications according to DIN VDE 0701-0702 with rated voltages up to AC voltage 1000V/DC voltage 1500V. What ist the best protection against electric shock caused by a powered device? The DIN EN 60335-2-69:2015-07 (VDE 0700-69:2015-07) is used for safety of electrical devices for domestic use and similar purposes. It is also valid for special requirements for power and water vacuum cleaners for commercial use. In particular, the insulation is an essential factor, because electric shocks are extremely dangerous and can cause serious damage. Therefore, this is necessary to prevent. The directive 2008/50/EC addresses air quality with regard to health. Clean air is essential at work. For this reason, certain measures ensure the reduction of emissions. Any output is to eliminate directly at the blowout point. The DIN EN ISO 16890 \"Air filters for general room air technology\" summarizes important characteristics of air filters. Testing and classification procedures enable a suitable filter selection according to the desired separation efficiency. In welding and related processes, DIN EN ISO 21904-1 / -2 (until 2020 DIN EN ISO 15012-1 / -2) describes a method for testing equipment for detecting and separating welding fumes. Good air quality at the workplace is necessary EN 1822-1: 2009 defines filtration performance of high-performance particulate filters (EPA); particulate matter filters (HEPA) and high-performance particulate matter filters (ULPA). The standard is the basis for, among other things, the identification and testing of the filter medium. The EU Chemicals Regulation (EC) No.1272/2008 (CLP) regulates the classification, labeling and packing of substances or mixtures that may be dangerous to people or the environment. After the risk assessment according to §6 the necessary protective measures have to be taken. Occupational Exposure Limits (TRGS 900) show the time-weighted average concentration of a substance in the workplace. The limit value indicates the concentration at which harmful effects of a substance are to be expected. Do you have any further questions?

Its ability to efficiently bind pollutants makes it particularly valuable for many industrial applications. But what exactly is activated carbon and how does physical adsorption work? What is activated carbon? Activated carbon has a highly porous structure with a large internal surface area. These properties enable it to adsorb a wide range of pollutants. During adsorption, molecules bind to the surface of a solid. This process is based on physical forces and takes place without chemical reactions. How does physical adsorption work? Physical adsorption is based on the Van der Waals forces that act between the molecules of the pollutants and the surface of the activated carbon. These forces are weak, but sufficient to hold molecules such as gases and vapors on the surface of the activated carbon. Since no chemical change takes place, the structure of the pollutants remains intact, which means that the activated carbon can often be regenerated after it has become saturated. When do you need an activated carbon filter? Activated carbon filters are particularly effective at removing the following pollutants: Organic vapors: These often occur in paint shops and when cleaning parts. Odors: Activated carbon removes unpleasant odors in food processing and waste treatment. Chemical vapors: Gases such as chlorine, benzene and ammonia are efficiently bound by activated carbon. Smoke: In metal processing, activated carbon helps to keep the air clean. Advantages of using activated carbon filters Using activated carbon filters in your extraction systems offers several advantages: Effective pollutant removal: Activated carbon can efficiently remove a wide range of pollutants. Improved air quality: Air quality is significantly improved by removing odors and hazardous vapors. Health protection: Reducing pollutants in the air protects the health of employees. Activated carbon filters are therefore an excellent solution for many industrial applications where clean air is a must.

An effective extraction system filters these contaminants from the air, ensuring a safe working environment and saving money in the long run by reducing sickness absence.   Learn more about how extraction systems can make your work environment safer and more productive:   Contaminated air in industrial processes poses a serious threat. Hazardous particles generated by welding and other activities can enter the bloodstream and cause serious illnesses such as lung cancer. Humans can only survive without air for a maximum of five minutes, and we breathe 12-18 times per minute. This underscores the importance of clean air.   Underestimated invisible dangers   Air is invisible, odorless and intangible, but it is essential to life. While we make conscious decisions about what we eat, we breathe unconsciously. We often do not think about what we are putting into our bodies. The concentration of pollutants increases greatly, especially in manufacturing processes. Natural filters such as cilia in the respiratory tract can only break down organic substances. However, industrial processes produce inorganic dusts, such as metal dust, that these natural filters cannot handle. These tiny particles are invisible to the eye and are often underestimated, even though they can have serious health consequences.   Limit values and the need for filtration   When a room is ventilated, air is exchanged between the room and the outside. In industrial environments, contaminant levels are often close to the acceptable limit of 50 micrograms per cubic meter. This means that additional contaminants enter the room when it is ventilated. An efficient filtration and extraction system is required to draw in the polluted air and bind the particles in integrated filters. After filtration, only clean air is released back into the room, protecting the health of employees.   Long-term benefits of a clean working environment   Employees are more productive and effective when they are less susceptible to illnesses caused by dusts in manufacturing processes. Health and safety are critical to business success. Today's high-tech systems require specialized personnel who need a healthy environment to work efficiently. Investing in the health of your employees pays off in the long run.   Economic effects of respiratory diseases   According to the German Federal Institute for Occupational Safety and Health (BAuA), respiratory diseases caused significant production losses in 2022. The average number of days lost per employee was 21.3, resulting in a total of 888.9 million days lost. The resulting economic output loss was estimated at 118 billion euros. *   Contact us today to schedule a consultation.   Our experts will analyze your specific needs and provide you with a customized quote for an extraction system that will protect your employees and optimize your production.

Precoating protects the filter cartridge from clogging and makes cleaning easier. The coating is applied prior to filtration. The precoat is metered to create an even layer for optimal protection. The cleaning process takes place after each filtration cycle. Compressed air pulses cause the particles to fall into the system's dust container. The precoating agent is added again to form a new layer on the filter. To ensure effective filtration, this process must be repeated at regular intervals, which significantly extends the functionality and service life of the filter cartridges, even with large amounts of dust or wet, sticky dust.

Especially in industry, employees are often exposed to the cumulative noise of many machines at the same time. In Germany, there are certain limits and regulations for noise levels in the workplace that must be adhered to. Legal basics: According to DIN EN ISO 11690 Part 1, operators/employers must ensure that noise exposure at workplaces does not exceed certain levels: Industrial workplaces: <80dB(A) Hearing protection is required from 85dB(A)! Office work: <55dB(A) Activities requiring special concentration: <45dB(A) The “Ordinance on the Protection of Employees from Risks Arising from Noise and Vibration” (LärmVibrationsArbSchV) and the “Ordinance on Occupational Health Prevention” (ArbMedVV) provide information on risk assessment and measurement. Noise is measured close to the worker's ear, often using a sound dosimeter. According to the Machinery Directive (MD), machine manufacturers are obliged to measure the sound pressure level of their system using a measurement method (e.g. EN ISO 3746) and to state this in their documentation. From a measured value of >85dB(A), both the sound pressure level (Lpa) and the sound power level (Lwa) must be stated. 2006/42/EC of June 9, 2006, section 1.7.4.2.u, valid from January 1, 2010: Workplace-related emission level   Workplace-related emissions level Spl  Required data 98/37/EG from June  22, 1998 2006/42/EG from June 9, 2006 (valid from 1.1.2010) < 70 dB(A) < 70 dB(A) Lpa < 70 dB(A) or Lpa = … dB(A) 71 – 85 dB(A) 71 – 80 dB(A) Lpa = … dB(A) > 85 dB(A) > 80 dB(A) Lpa = … dB(A) and Lwa = … dB(A) 1)   Table 1: Sound emission values according to EG machine guideline. Extraneous noises and the room itself (reflexing parts) are not calculated in the workplace-related emission level SPL. However, it contains susceptible supplements for measuring accuracy. 1) Lwa: Sound power level If a machine is not part of exactly one workplace (e.g. a filter and extraction system), the measuring of noise emissions will be those of the system itself. The data does not evaluate the noise emissions within the room.         Sound level basics The sound power level (LW) indicates the sound power W radiated by a sound source and is measured logarithmically. LW=10logW/W0 W0 is defined as 10-12 W (or 1 pW, reference sound power). If the total sound power is distributed over an area of 1m2 (e.g. a hemisphere with a radius of r = 0.4 m), the sound power level and the sound pressure level at this distance are numerically the same. If the sound power level is given in dB(A), the following two notations are permissible: LWA in dB or LW in dB(A).     Sound emission measurements on machines, Suvapro, Lucerne It is not technically possible to measure the noise emission of a single system in a workplace using normal measuring instruments, since the environmental factors cannot be excluded from the measurement. These measurements will therefore never match the machine manufacturer's specifications. Important: In a room in which several machines are operated, the higher the sum of all sound power levels, the louder it will be. However, sound levels cannot be calculated in the same way as normal numbers – there is a logarithmic relationship. For example: Machine 1: 80db(A) + Machine 2: 80dB(A) = 83dB(A) Note: An increase in sound level of 10dB(A) is perceived as a doubling of the noise. People find low frequencies less annoying than high frequencies. The machines should always be arranged so that the sound radiation is not directed towards the worker. Soundproof walls and special soundproof ceilings provide additional insulation. Sources: BGHM – DGUV Information 209-023, Machinery Directive 2016/42/EC Optimizing noise levels at the workplace Place the extraction system at least 2 meters away from the operator. Set up the system behind other machines or walls. Reduce the suction power to reduce noise levels and energy consumption. Often a 10% reduction in suction power will have a positive effect on noise levels and save a lot of energy. Sharp edges, high flow velocities, and turbulence create unpleasant noise and greatly reduce extraction efficiency. Use pipes, hoses, or silencers to direct exhaust away from workstations. Switch off the extraction system during breaks or reduce the suction power. Let the TBH team advise you. Practice – two different worlds: Machine manufacturers test their machines individually. In practice, however, they are used in rooms of different sizes and in combination with other machines. Machine operators need to take into account all environmental conditions in their measurements to ensure the health of their employees. Machine manufacturers are not required to include ambient conditions in their sound level measurements. This is the responsibility of the operator, who is responsible for the entire workplace. Machine manufacturer: Noise emitted by individual equipment Operators: Noise immission on the employee Conclusion The sound pressure level specified by the machine manufacturer cannot be used 1:1 to assess the noise exposure at the workplace. All sound sources and spatial influences must be taken into account to determine the actual noise exposure and to take appropriate measures to protect employees.

These include, firstly, the Product Directive 2014/34/EU and, in addition, the Operational Directive 1999/92/EC, which has been in force since April 2016. As a result, these directives set standards for equipment and protective systems in potentially explosive atmospheres that must be transposed into national law by EU member states. Fundamentals of the ATEX directives The main purpose of the ATEX directives is to protect people in potentially explosive atmospheres. Accordingly, manufacturers must comply with essential health and safety requirements and demonstrate this through conformity assessment procedures. In addition, the ATEX directive applies to explosion-protected electrical and mechanical systems, components and protective systems. Since July 1, 2003, only these may be used in potentially explosive atmospheres. In Germany, the EU Directive was implemented into national law by the Explosion Protection Products Regulation (11th ProdSV). Explosion Hazard in the Workplace When handling substances that react with oxygen, there is a risk of explosion if: Oxygen is present in a space volume with a certain partial pressure Oxygen is suspended in the air as a fine-grained dust The proportion of flammable gas is between the lower and upper explosion limit = explosive gas-air mixture Furthermore, an explosive atmosphere can be created by the dispersion of combustible substances in the air. The explosion triangle makes it clear: flammable substance + oxygen + ignition source = explosion Primary explosion protection: Avoid explosive atmospheres Secondary explosion protection: Avoid effective sources of ignition Tertiary explosion protection: Constructive explosion protection ATEX equipment group classification Since the introduction of EN 60079-0:2009, systems have been divided into three groups: Group I Group II Group III Mines at risk of firedamp - depending on explosive substance - Hazard increases from A to C Explosive gases, which are divided into the following subgroups for some types of ignition protection (EX i, EX d, Ex n): IIA IIB IIC Dusts are subdivided into Fiber IIIA Non-conductive dusts IIIB Conductive dusts IIIC Ex d = Flameproof enclosure Ex i = intrinsic safety Ex n = depending on the type, Ex nA or Ex nL or Ex ic Subgroup A: gasoline, diesel, ethane Subgroup B: town gas, ethylene, hydrogen sulfide Subgroup C: hydrogen, carbon disulfide TBH extraction systems for explosion-proof areas TBH offers extraction systems for explosion-proof areas that comply with the ATEX Product Directive 2014/34/EU and the DIN EN 1127-1:2007 standard. Here, systems in a category may only be used for certain zones; for example, category 2 systems are only permitted for zone 1 (for gases and vapors) or for zone 21 (for dusts). The following factors must be considered when selecting an extraction system: Type and quantity of the material to be extracted Possibility of reducing the released quantity Contaminated air collection method Existing ATEX zones and regulations Necessity of an ignition hazard analysis Based on these findings, the operator defines the ATEX zones in their production. For this, an ATEX consulting service provider can also be used. They can also create an explosion protection document. After evaluating the risk posed by the released substances and classifying the zones, the appropriate extraction system can finally be selected. TBH employees check the process parameters (amount of dust or gas, capture, required air volume flow, etc.) and the customer's zone classification. How is an ATEX system monitored? When a system is operated in accordance with 137, it must be regularly inspected by approved inspection bodies in accordance with the Industrial Safety Regulation. To have the necessary expertise, qualified inspectors have professional training and experience and have recently carried out the activity. Systems must completely prevent the ignition of explosive atmospheres or at least reduce the effects to a sufficiently safe level. The inspection is carried out by TÜV Süd. The CE mark is used for products whose manufacture must be supervised by a notified body. It applies to systems with an EC type examination certificate from a notified body (electrical equipment 0, 20, 1, 21 including combustion engines) and mechanical equipment for zones 0, 20. Finally, systems and protective devices covered by the directive require a CE marking, an EC declaration of conformity (confirmation of compliance with the essential health and safety requirements) and a conformity assessment procedure. Only then can products be made available on the EU market, whether for a fee or free of charge.

Lasers produce fine particle emissions with size distributions of 0.1 μm when processing different materials. These nanoparticles are especially harmful to humans because of their small particle sizes, as they can deeply penetrate into lungs and bloodstream. It is even more relevant knowing what defines a hazardous substance and which protective measurements exist. Hazardous substances are chemical or artificial, and naturally produced substances or mixtures. Some are harmful to humans only after reactions with other substances and have characteristics such as toxic, irritating or corrosive. Nonetheless, dusts of harmless substances can be dangerous as well. They consist of tiny particles that can be inhaled or absorbed through skin contact. For example, welding technology releases hazardous substances that appear in particulate or gaseous forms. The chemical composition and concentration of emissions such as welding fumes are free from the materials and the methods used. Particles released may be A-dust and thus respirable or E-dust which may pollute the upper airways. The limit values are 1.25 mg / m³ for a dust and 10 mg / m³ for E dust. Airborne swirling can cause explosive dust-air mixtures with a very low explosive limit of 15 mg / m³, even if the dust is deposited at a height of 1 mm. Hazardous substances in welding work Examples of hazardous substances are complex mineral oil, coal and natural gas derivatives (former EC Directive 67/548 / EEC, since June 2015 Globally harmonized system for classification and labeling of chemicals (short GHS)), so-called CMR substances according to the Institute for Occupational Safety and Health (IFA = German “Institut für Arbeitsschutz”)) and explosive or highly flammable substances. According to GefStoffV §10 par. 5 (German Ordinance on Hazardous Substances), extracted air with CMR substances of category 1A and 1B are not allowed to be released into the air. The IARC, a specialized department of the WHO, classifies substances with regard to the hazard potential to humans. In Group 1 are carcinogenic substances such as welding fume, tobacco, UV radiation and chromium IV components. CMR particles = Carcinogenic, mutagenic, toxic to reproduction Effect on people Category 1A Is proven Category 1B Is very likely because it is proven on animals Category 2 Is to assume Safety is the top priority The employer must respect the safety of his employees at work and point out any potential danger to them. Regular cleaning and ventilation is essential, especially when dealing with CMR substances. Most technical rules and standards assign the following technical protection measures in such processes: Avoiding extract directly at point of emission measuring ventilation having personal protective equipment Therefore, one of the most important protective measurements for the employees is effective detection from dusts at the point of origin. The employer must provide his workforce with special protection in case the employees work with explosive substances. In general, a risk analysis of the target process provides information about the requirements of a suction concept and clarifies the actual hazard potential. Tested air filtration system When separating non-explosive hazardous substances in circulation operation, the operator has to carry out the extraction system's separation degree while commissioning by means of an officially tested procedure. If no separation degree has been adequately proven, the filtered air must be discharged to the outside. The emission rate has to be tested once a year, as well as before commissioning and when major changes are made to the system. In addition, the systems must be maintained once a year according to the manufacturer's instructions. Alternatively to the separation rate determination at commissioning, the operator can use a type-tested filter and extraction system with a confirmed separation rate, e.g. according to DIN 60335-2-69 AA, or a confirmed separation rate according to W3. The W3 welding smoke approval is an officially tested degree of separation of the filter classes and is necessary when depositing hazardous substances. A certification of the entire system is not mandatory, but merely serves as a supplement to the legal guidelines. TBH filtration and extraction systems have a degree of filtration according to W3 confirmed by the IFA and they can be used to extract CMR substances as well. The systems are suitable for automation technology because they are equipped with an H13 filter, a signal on the display, a volume flow meter, a signal unit and an interface that evaluates errors. When dealing with hazardous substances, employees have to observe the following rules: Observe safety regulations (§ 7 par. 4 German Ordinance on Hazardous Substances) Do not eat if there are hazardous substances in the room. Wash hands and, if necessary, change clothes after leaving the work area. Do not fill hazardous substances in food containers. Do not try to identify a hazardous substance on your own. Train employees concerning potential risks. Pay attention to the correct labeling of containers with hazardous substances. Use substitutions for hazardous substances if possible. Comply with occupational exposure limits Detection of the emissions as complete as possible, directly at the point of origin with a suitable extraction and filter device Failure of the ventilation device must be recognizable to all (TRGS 500) Use emission-free or low-hazardous processes and additional materials (§ 7 par. 4 German Ordinance on Hazardous Substances) Clean transition zones and working areas with officially recognized vacuum cleaners of dust class H (DIN EN 60335-2-69 [15], TRGS 517) Connect lead-resistant workstations to stationary extraction systems and provide mobile suction systems (TRGS 505)   Since December 2010, a globally uniform classification and labeling of chemicals has become valid and has to be observed.

The dust particles are only a few micrometers in size and therefore invisible to the human eye. The suspended matter is subdivided into the so-called PM categories, which differentiate particles according to their sizes. The term \"Particulate Matter\" is derived from the current definition by the US Environmental Protection Agency (EPA), which sets the \"national air quality standard\". Why is particulate matter dangerous? The particles in particulate matter are very small and carcinogenic. The smaller the particles, the deeper they can penetrate the lungs when inhaled and remain there. When measuring particle sizes, the focus is on the respirable levels of immissions. The smaller the particles, the deeper they can get into the lungs and cause irreparable damage, which can lead to lung cancer. Suspended dust includes all airborne particles. These are subdivided into PM10, of which half of the particles have a diameter of 10 μm. The other half consists of PM2.5 with a particle diameter of 2.5 mm and smaller.  For example, modern laser processes emit particles in the range of nanometers, which is only one millionth of a millimeter. The concentration of the smallest particles is increasing steadily nowadays, while the number of greater particles is decreasing. This results to a rising danger to humans. The simulation of the internal airways allows the measurement of the particle concentration in the deposition process. Particles with an aerodynamic diameter of 10 micrometer are fully sucked into the inner airways to the bronchi. The evaluation of the larger particles is based on their percentage, which decreases with advancing size and reaches 0% at approximately 15 μm. Since 1997, the directive 2008/50/EG has been supplemented by PM2.5. It measures respirable particulate matter and defines ultrafine particles with a thermodynamic diameter of less than 0.1 mm. In addition to the particle sizes, dusts can also be classified according to their nature, formation, physical properties, chemical compositions, shape or color. For example, other models determine the material’s structural toxicity or perpetrator. However, a full consideration is only possible with the inclusion of multiple models. Which guidelines apply to particulate matter regarding to the used filters? Previously, particulate matter was assessed according to the DIN EN779. However, this only referred to the particle size 0.4 µm and evaluated the efficiency of an air filter as an average over a load of synthetic laboratory dust. Due to its limited informative value, it has been replaced by the DIN EN ISO 16890. It came into force in January 2017 and has been valid since mid-2018. The ISO is also used by the WHO and divides the filters into four groups. The degree of separation determines the affiliation. A filter must deposit at least 50% of the respective particle size. For example, an ISO ePM1 filter deposits at least 50% of the PM1 particles. If a filter separates less than 50% PM10, it falls into the category coarse dust filter (= ISO coarse). The e stands for efficiency. The respective percentages indicate the percentage of the corresponding particles that the filter deposits. What are the causes and consequences of particulate matter? Particulate matter can cause respiratory diseases, asthma, allergies or cardiovascular diseases. Fine dusts from inorganic substances such as metal dusts are particularly critical. The body cannot break them down. Permanent exposure to high dust concentrations leads to an overload of the lungs' cleaning mechanism in the long term. The dust particles then demonstrably stay in the lungs. As a result, chronic bronchitis can develop. 1 Only an air filter and extraction system can provide adequate protection. 1 Source: https://www.dguv.de/staub-info/erkrankungen/reinigungsmechanismus-der-lunge/index.jsp (DE) Do you have any further questions?

Which are the advantages of modular design for filter and extraction systems? The modular design, or modular principle, describes a division of an entity into parts, which are referred to as units, components, elements or modules. They have uniform interfaces, which make it easy to combine them. The air filtration system can be adapted individually to each customer's requirements. The dependencies between the components are kept low. At TBH, filter and extraction units with a modular design have one unit for the engine, one for the lid and at least one for the filter. Several filter units can be installed into a system one by one, or be supplemented with other units such as spark extinguishers. Depending on pollutants and particle concentration in the air, the filters complement each other in order to be geared to fitting the required processes even better. Another advantage is, when changing the filter, only the respective saturated filter has to be replaced without completely dismantling the system. Visually, the systems look similar, but their units are differently composed, which make them suitable for various processes. Each system is therefore versatile. The units are manufactured individually and can be easily assembled / integrated on demand into an ordered system as desired. This enables a flexible and fast manufacturing process and thus shorter production cycles. Simply exchanging and upgrading units of an air purification system Due to the simplified structure, the functionality of the system is always given. Individual parts are easily and without the use of tools interchangeable like toy bricks without disassembling the whole system. There is no screwing and finishing work required. No difference is recognizable after the installation of the replaced units, and therefore it is instantly fully functioning again. Complex systems also appear easier to understand, because they are simple in design. Upgrading with an activated carbon module is also readily possible. Work processes are fast-paced. The modular design makes it possible to adapt the system to changing requirements directly, quickly and cost-effectively. The customer has a short waiting time after ordering, as the units are simply put together. This saves much time, because in contrast to the integral structure the system has not to be completely rebuilt. In addition, systems can be more easily adapted to the respective processes. The flexible structure allows us to meet the customer’s requirements even more. Building individual units, instead of entire systems in one part, also reduces storage and production costs. The design simplifies error analysis as well, because each unit can be checked individually. In identical series, the repair is inexpensive, because of the uniform units, which are identical in all systems. In a modularized design, systems are components assembled along defined interfaces. The opposite construction form is an integral structure, which is also called monolithic (Greek: monólithos - the Einstein). This may refer to real or intangible objects.

W3 is a certification by the IFA (Institute for Occupational Safety of the German Social Accident Insurance) and is required for safe extraction of welding fumes. Since 2018, the WHO has classified welding fumes as definitely carcinogenic to humans (IARC 118,2018), making almost no distinction between processing low-alloy and high-alloy steel. In Germany, welding fumes from processing high-alloy steels must be extracted and filtered using W3-certified equipment (TRGS 560). The degree of separation indicates a filter's performance. Welding fumes are classified into so-called W classes. The limit values for harmful particles depend on the processed materials and the used welding process. Particles in welding fumes have a size of less than 1 µm. From a size of less than 10 µm, the particles are respirable, while below 0.1 µm they are considered nanoparticles. The concentration of pollutants produced during welding is carcinogenic according to the Technical Rules for Hazardous Substances (TRGS). Natural human filters, such as cilia or nose hairs, cannot catch them. The recirculation of air into the work area during welding is generally prohibited according to the Ordinance on Hazardous Substances. Unless it is done with a filter extraction system that is certified in accordance with DIN EN ISO 15012-1 \"Occupational safety and health in welding and allied processes\" Class W3. In this case, the air can also be recirculated after extracting carcinogenic pollutants such as chromium or nickel. W3 filters certified by IFA separate fumes and dust from high-alloy steels with a separation efficiency of 99%. The air filtered by the certified equipment can be returned to the ambient air. The filter system has to be tested at least once a year to ensure effective operation. Class Separation efficiency Usable for W1 > 95 % Unalloyed or low alloy steel W2 > 98 % Alloy steel with 5 – 30 % nickel and chrome parts W3 > 99 % High-alloy steel with > 30 % nickel and chrome parts TRGS560 and TRGS528 are not only used for the evaluation of classic welding, but also for all thermal processes in which high-alloy steels are processed, such as welding, cutting and laser marking. The tests by the internationally recognized Institute for Occupational Safety confirm the degree of separation and thus the safety and performance of welding fume separators. TBH fume extraction systems have a W3 marking. DIN EN 15012-4 evaluates the machine and filter change. Our air filtration systems are labeled 'DGUV tested' and are included in the positive list of the IFA as tested devices. Up to a particle size of 100µm, the limit value for respirable dust determines the required filter performance. If the limit value is above 10 milligrams per cubic meter, the maximum value, based on a particle size of 10µm, is 1.25 mg/m³. Systems with H13 filters have a sufficiently high degree of separation even without the W3 test. The systems must be checked at least once a year for the effectiveness of the filters to protect the employees. Due to their high degree of separation, TBH filter and extraction systems of the H class and with W3 labeling of hazardous substances can be used if the discharged air is to be returned to the working area.

ESD (Electrostatic sensitive devices) is an exchange of static electricity between two bodies. The electric charge can be generated by friction between two different materials, e.g. on synthetic clothing or when moving plastic containers. ESD is caused by a lack or excess of electrons on a body's surface. These bodies have an ESD potential on their surface and can affect neighboring and/or adjacent bodies due to the created electrostatic field, posing a significant risk in various production processes. Electrostatic charging can occur in almost any body. The electronic energy that can accumulate in the human body is about 10-30 milli-joules. The strength of the electrostatic field can be up to 20 kV. With a current flow of up to 100 A/ns, short-term discharge currents of up to 30 A can be achieved. Due to the charge generated by friction, e.g. when walking on carpeted floors, contact with sensitive components can damage them. Electrostatic discharges generate voltages of several 10,000 V due to frictional electricity. So-called Electrostatic Protected Areas (EPA) can be set up at the workstations for protecting ESD-sensitive components. The workplaces have conductive and grounded table and floor coverings, so-called ground potential reference surfaces, as well as grounded tools. The workers' clothes and shoes are made of antistatic material. The Screen Equipment Regulation includes measurements to reduce electrostatic discharges and protect health. There are the static discharge as well as the inductively induced interference, the electromagnetic interference (EMI). ESD classes Voltages that cause damages ESD class 1 Sensitive against ESD voltages between 0 V and 1.9 kV ESD class 2 Sensitive against ESD voltages between 2 kV and 3.9 kV ESD class 3 Sensitive against ESD voltages between 4 kV and 15.9 kV ESD class insensitive Sensitive against ESD voltages above 16.0 kV ESD safety shoes are designed to protect against electrostatic discharge. ESD discharges in workplaces can be the cause of serious accidents (e.g. start a fire near flammable materials), as well as damage machines and their sensitive components. ESD labeled footwear differs from normal safety footwear, which only has an antistatic marking (A), i.e. it constantly discharges the static electricity accumulated by the human body to the ground. Their use is regulated in accordance with EN ISO 20345:2011. Whereas an antistatic shoe has an electrical resistance of 100 kiloohm to 100 megohm, an ESD shoe has an electrical resistance in the range of 100 kiloohm to 35 megohm. An ESD shoe is always antistatic, but an antistatic shoe does not necessarily fit into the ESD category. A yellow marking makes it immediately recognizable. The marking is separate from the CE marking, as this is a standard in the product protection industry. If the shoes or clothing meet the standard, they are marked ESD. A marking with SI indicates antistatic. ESD in TBH filter and extraction systems All TBH filter and extraction systems are made of high-quality sheet steel and are accordingly conductive. For this reason, all TBH systems are classified in the protection class I for electrical equipment. Devices of the protection class I must always be earthed with low resistance in order to prevent damage from the operator / maintenance personnel in the event of a fault. In the test field, earthing is ensured by a 100% initial test in accordance with DIN EN 61010 (thereafter repeat test in accordance with DIN VDE701 / 702). The limit value is <0.3 ohm (with cable lengths <5m). Equipotential bonding between the system parts ensures that the system cannot charge in the airflow. This provides additional security. The demand from ESD environments for a discharge of electrostatic discharges is based on a high-resistance resistor according to IEC 61340-5-1 <35 megaohm, in order to keep the leakage currents low. This protects sensitive electronic components from overvoltage. The protection of humans has the highest priority. Therefore, the user must not come in contact with the extraction system. Capture elements can be grounded using their ground connection with high resistance to the system. Thus, a touch is not a problem. The system should be placed under a worktable so as not to be in the normal working environment. During maintenance work, attention must be drawn to any critical electronic components in the environment or to remove the system from the ESD area during maintenance.

Consider the preferred degree of separation, which has to be achieved, and the type of dusts, which has to be removed. Filters of class H are particularly effective and work for very small particles like hazardous dusts. The dust classes are divided into three groups, which are L, M and H. For the filter dust classes, L defines coarse-grained, M slightly finer and H the finest dust, while the dust classes regulate the use of the systems.   Dust classes overview   Dust classes of filter and extraction systems Usable for Fielding L – slightly hazardous dusts Common house dust, sand, gypsum, lime, as well as allergenic substances such as mite and pollen Household M – medium hazardous dusts Wood dust, paint particles and various metal dusts Small companies, for more control and transparency H – highly hazardous dusts Suitable for highly dangerous and carcinogenic substances such as mold spores, lead dust, mineral fibers Companies with hazardous substances, extremely well filtration, highest security Systems of dust class H must be maintained and checked regularly once a year by the operator in order to not exceed the legally prescribed occupational exposure limits (German Arbeitsplatzgrenzwerte = AGW). In case of additional hazardous dusts, the protection of the employees is based on the measurement of the air velocity in detection elements, hoses and pipes as well as a dust-reduced (Class M) or dust-free (Class H) filter disposal. Safety vacuum cleaners that comply with dust class H can only draw in asbestos dusts. In Germany, these cleaners must additionally fulfill the requirements of TRGS 519 No. 7.2 par. 6. Special vacuum cleaners are used, which have been particularly approved for explosive and flammable dusts, in accordance with the ATEX directives. Classes L and M may be used for non-carcinogenic dusts with AGW values > 1.0 mg / m³ or flammable dusts for applications in ATEX zone 22. Generally note:  In general, it should be noted that a large part of the risk of unrecognized particles originates at the point of origin. If only 80% are captured at the point of origin, the regulation of the degree of separation is not expedient. It is important to ensure the correct lead of supply air and exhaust air with the aid of indoor air measures in order to ensure a sufficient supply of fresh air. Turbulences may occur. Since 1998, the international standard DIN EN 60335-2-69 has been used as the base of evaluation for dust-removing machines (SBM) in industrial uses. It defines the intended suitability of the devices and classifies them according to the different testing basics. With the new Hazardous Substances Ordinance, the values of the \"Maximum Workplace Concentration\" (MAK) were replaced by the AGW limits. DIN EN 60335-2-69 differentiates between dry, unhealthy and flammable dusts and assesses their classifications. The guidelines for ventilation and air conditioning systems (RLT) of July 2011 apply to a system certification. The dust class H according to DIN EN 60335-2-69 as a filter class is not comparable with the generally known filter classes according to DIN EN1822. The guidelines mentioned are based on various measurement and test regulations that work with different test aerosols, measuring methods and particle sizes. It is thus possible for a filter according to DIN EN1822-E10 to meet the requirements of a dust class H deposition in measurements. This is due to the fact that the specified permeability of 0.005% has nothing to do with the filtration efficiency of 99.995% of the filter class H14 (according to EN1822). Test aerosols with particle distributions of 0.1-0.3μm are used in EN1822, 99.95% for filter class H13 and 99.995% for H14. Filters are 100% tested. Currently, no test standard with particle measurements smaller than 0.1μm is available. It is to assume that smaller particles do not simply migrate through the filter material, but are attracted to the mass attraction of the filter grid. The particle filters used by TBH according to EN1822 with a separation efficiency of H13 are the best protection against particles of any kind and even exceed the requirements of DIN EN ISO 21904-1 / -2 (until 2020 DIN EN ISO 15012-1 / -2).

Together, we talk about laser marking, laser cleaning, and laser safety in industrial practice. On March 9, 2026, TBH was a guest at Laser Lounge in Chemnitz. Three podcast episodes were recorded there. You can watch the trailer for the first episode here (the video is in German with automatically translated subtitles) and the full first episode on the Laser Lounge YouTube-Kanal. Two more episodes on laser cleaning and safety and best practices will follow in May and June.   Why laser smoke and extraction are important Laser applications are precise and efficient. At the same time, they produce emissions such as fine dust, particles, and vapors. That is why suitable extraction for laser applications is important. It protects employees, machines, and the environment. TBH focuses on solutions to protect humans, the environment, and machines. What is the podcast about? The podcast highlights three key topics from practical experience. Laser marking and extraction The first episode is about laser marking. TBH and Laser Lounge talk about materials, system differences, and the right extraction system. This is because different materials produce different emissions. That's why the filter and extraction concept must also be suitable for the application. Laser cleaning and safe detection The second episode deals with laser cleaning, especially for injection molds. Here, it becomes clear how important it is to detect emissions directly at the source. This is because cleaning does not simply make the contamination disappear. It is transferred into the air and must be safely subjected to extraction. Laser safety in practice The third episode deals with laser safety, standards, and occupational safety. The focus is on practical questions. What do companies need to consider? Which protective measures are sensible? And how can a safe solution be implemented in everyday life? Who might find the podcast interesting? The podcast is aimed at companies that work with laser applications. These include production, occupational safety, EHS, and metal and plastics processing. The series is particularly relevant for anyone who wants to learn more about laser smoke, extraction, and safe processes. Conclusion The new podcast on laser smoke and extraction shows why laser processes should be viewed holistically. Good results are not only achieved by the laser itself, but also by suitable extraction and filter technology.

While this is true, in practice it doesn’t tell the whole story. That’s because laser-based processes are not just about removing emissions from the work area. They’re also about stable operations, clean machine environments, and reliable production conditions. Depending on the method, material, and process control, laser cutting generates smoke, fine dust, and very small airborne particles. Some of these are so fine that they cannot be seen with the naked eye. This is precisely what makes the issue so challenging. What is invisible is quickly underestimated in everyday life. Why extracting laser smoke is more than just occupational safety In many companies, extraction technology is still primarily viewed as a protective measure for employees. This perspective is understandable, but it is not the whole picture. Those who wish to extract laser smoke often influence far more than just the air in the immediate work area. Fine particles can spread throughout the environment, settle on sensitive components, and compromise overall cleanliness in the process. This can have implications for maintenance, equipment availability, and the consistency of manufacturing conditions. In short: Clean air is not just a health issue. It is also a process issue. How small particles from laser processes can be The issue becomes particularly relevant due to the particle sizes described in scientific studies. In a study on the cutting of 10 to 30 mm thick austenitic 304L stainless steel plates with a high-power fiber laser, a count median aerodynamic diameter of approximately 0.12 µm was measured for the resulting aerosols, or about 120 nm [1]. In the same paper, the authors also describe that the aerosol concentration decreased by nearly 30% as the cutting speed increased, depending on the conditions [1]. This clearly demonstrates that emissions from laser processes do not depend solely on the material. Process parameters also play a significant role. Even smaller particles were observed in a study on laser-based additive manufacturing of metal components. There, the vast majority of the primary particles formed were in the range of 4 to 16 nm. The reported median values were 8.0 nm, 9.4 nm, and 11.2 nm for the processes investigated [2]. Three laser-based additive manufacturing processes using stainless steel powders were examined. These values cannot be generalized to every laser process. However, they make it clear that particles in the nanometer range can be generated in metal-based laser processes [2]. What these orders of magnitude mean in technical terms This is precisely where context is needed. Not every small particle size automatically equates to a specific level of exposure. Nevertheless, such size ranges help to assess the issue more realistically. According to NIOSH, particles up to roughly 100 µm are considered inhalable. Particles in the PM10 range are considered thoracic, and particles in the PM4 range are considered respirable [3]. This means: They can penetrate as far as the alveoli of the lungs. The WHO also points out that fine particles such as PM2.5 penetrate deep into the lungs and can in some cases travel further into the body [4]. This makes it clear why laser smoke extraction should not be viewed solely from the perspective of “smoke must be removed.” When studies describe aerosols of around 120 nm or primary particles in the range of 4 to 16 nm [1][2], it is clear that very fine emissions can play a role here. This is precisely why technically appropriate collection and filtration are essential. Not every laser process generates the same emissions Equally important is the technically sound caveat: Not every laser process generates the same emissions, and not every measured particle size can be easily applied to other applications. That would be too sweeping a generalization. The decisive factors are always the material being processed, the specific process, the power, the process control, the airflow, and the specific design of the collection system. Laser cutting, laser marking, laser cleaning, and laser-based additive manufacturing are not the same. Even within a single process, changes in material or process parameters can influence emission behavior. This is precisely why a good solution requires not blanket promises, but a sound technical design. What effective extraction must achieve in practice Anyone seeking to extract laser fumes needs more than just general air movement in the room. It is crucial that emissions are captured as early as possible and as close as possible to the source. The better this is achieved, the lower the likelihood that particles will spread uncontrollably into the surrounding area. A well-designed extraction and filtration solution can help to reduce exposure in the work environment, remove fine emissions directly from the process, keep sensitive areas of the facility cleaner, reduce deposits in the surrounding area, lower maintenance costs, and support more stable conditions in production.   That sounds technical, but in practice it is very concrete. Where fewer emissions remain in the environment, operational safety often increases as well. And where processes run more cleanly, quality and availability are frequently enhanced at the same time. Extracting laser smoke as part of stable manufacturing Ultimately, it is not just about a single protective measure. Those who need to extract laser smoke are simultaneously determining part of the process quality. Clean air at the source can help protect people, keep machines cleaner, and make production conditions more reliable. That is precisely where the real added value lies. Extraction is not a peripheral issue that begins only after the process. It is a technical component of a well-designed manufacturing process.

In many industrial and sensitive applications, emissions are generated during machining, cutting, welding, soldering, grinding, or laser cutting—emissions that can harm employees, disrupt processes, and contaminate machinery. These include dust, smoke, aerosols, vapors, gases, and odors. It is therefore crucial not only that air is filtered, but also where and how: as close as possible to the source, tailored to the process, material, and environment. Why is air filtration in the workplace important in industry and sensitive applications? In many processes, airborne pollutants enter the work area directly. Without proper capture, they can spread throughout the room and enter the breathing zone of employees. Depending on the substance, particle size, concentration, and duration of exposure, this can increase health risks while simultaneously tightening requirements for occupational safety, risk assessment, and exposure control. Air filtration therefore serves not only to protect employees but also to ensure process stability, maintain a clean work environment, and prevent deposits in equipment, enclosures, and technical components. What pollutants are generated during laser cutting, welding, soldering, grinding, or transfer processes? The type of emissions depends on the process and the material being processed. Welding produces fumes and particulate matter; laser cutting typically produces very fine and ultrafine particles, as well as gaseous decomposition products depending on the material. Soldering produces gaseous components in addition to particles. Grinding, dry processing, or transfer operations can release respirable and alveolar dust. In sensitive medical applications, smoke or a plume is additionally generated. Depending on the application, this may contain chemical and biological components. Therefore, the selection of a filtration and extraction solution should always be process-specific. There is no one-size-fits-all solution for all emissions. Why is capture at the source usually more effective than general ventilation? Contaminants should be captured wherever possible at the point of origin. This prevents them from spreading throughout the room in the first place and significantly reduces their entry into the breathing zone. It is precisely this principle that occupational safety and technical sources in Europe and the U.S. describe as a key measure for reducing exposure. Local capture at the source is therefore more effective in many applications than simply general ventilation of the room. This is especially true when emissions occur at specific points and continuously. The closer the capture system is to the source, the better the spread in the work environment can be limited. Why are general ventilation or room air purification alone often insufficient? General ventilation and supplementary room air measures can be useful. In many applications, however, they are only a supplement and not a substitute for source capture. The reason is simple. If a contaminant is first diluted in the room, it may have already spread throughout the work area beforehand. This is a significant difference, especially in emission-intensive processes. Local capture acts sooner and reduces exposure where it originates. How does air filtration protect not only employees but also processes and machinery? Filtered process air not only reduces the burden on employees. It can also help keep work areas cleaner and protect technical components from deposits. Less dust and smoke in the environment often means less cleaning effort. Enclosures, surfaces, and sensitive components can also be better protected this way. This is particularly relevant in integrated systems, in electronics manufacturing, and in sensitive production environments. There, air quality often has a direct impact on stability, cleanliness, and maintenance requirements. Air filtration protects These initial insights show why air filtration at TBH is not viewed in isolation, but always takes people, the environment, and machinery into account. Air filtration helps effectively capture emissions at the source, protect employees, keep work environments clean, and maintain stable processes. What limits and regulations apply to air filtration in the workplace? The specific legal situation depends on the country, the substance, and the process. Within the EU, Directive 98/24/EC on chemical agents and Directive 2004/37/EC on carcinogenic, mutagenic, or reprotoxic substances, among others, form important foundations. They are implemented at the national level and supplemented by country-specific requirements, guidelines, and limit values. In Germany, the TRGS and workplace limit values, among others, are relevant. TRGS 900 specifies a general dust limit value of 1.25 mg/m³ for respirable dust and 10 mg/m³ for inhalable dust. TRGS 528 describes requirements for welding operations. These regulations apply nationally in Germany. When is recirculation possible, and when is exhaust air the better solution? There is no one-size-fits-all answer to this question. Whether purified air can be recirculated into the room always depends on the specific application. Relevant factors include material properties, potential gas content, the hazard potential, and nationally applicable requirements. The filter configuration, the actual process control, and the required documentation also play an important role. In some applications, recirculation is technically and regulatory feasible. In other cases, exhaust air is the safer or mandated solution. Therefore, this decision should never be made in isolation. The risk assessment and the applicable national regulations are always decisive. How do you find the right filter and extraction solution for your specific process? The right solution is not determined by a filter class alone. The decisive factor is the interplay of application, material, capture conditions, and operational requirements. Important questions include, for example: What emissions are generated? How fine are the particles? Are there additional gaseous components? How high must the air flow rate be? How can the solution be integrated into the existing process? In addition, there are requirements regarding maintenance, disposal, noise levels, and installation location. The question of whether a system should be mobile, integrated, modular, or suitable for sensitive environments is also often decisive. A modular design makes particular sense when requirements change or grow. This allows the solution to be better tailored to the specific process and adapted as needed. For which applications is process-integrated air filtration particularly relevant? Process-integrated air filtration is particularly relevant wherever emissions are generated directly within the process. This includes, for example, laser fumes, welding fumes, soldering fumes, dry dusts, transfer processes, plastics processing, as well as cleanroom and controlled environment applications. Capturing emissions at the source also plays a crucial role in sensitive medical or aesthetic applications. In these settings, it is not only about the filtering effect but also about airflow management, integration, and suitability for the specific environment. In the medical field, a clear classification also applies. TBH systems are not sold there as medical devices, but as accessories for extracting air directly during laser treatment on the patient, without patient contact. Why should air filtration be incorporated early in the process planning? The earlier air filtration is incorporated into the process planning, the better the capture, integration, and effectiveness can be tailored to the application. This allows for the sensible planning of airflow, installation space, enclosure, maintenance, filter replacement, noise, and interfaces at an early stage. If extraction is only considered at the end, it often has to adapt to conditions that have already been established. This makes effective capture at the source difficult and can unnecessarily complicate later integration. Air filtration is therefore not just a matter of occupational safety. It is also a matter of process reliability and technical planning. Key Takeaway Air filtration is most effective when it is considered early on, tailored to the specific process, and implemented as close as possible to the source. In this way, it helps protect employees, keep work environments clean, and reliably support processes. Find the right solution for your process.

Why effective extraction directly at the source is important—and what matters most in laser processes used in manufacturing and toolmaking.", "fulltext": "Extraction Systems for Laser Cleaning: Why They Are Important Extraction systems for laser cleaning are a critical component of industrial laser processes. Laser cleaning selectively removes rust, paint residues, or metal oxides from metal surfaces—for example, as a pretreatment in toolmaking, manufacturing, or surface preparation. The process is highly precise. At the same time, however, it generates smoke, fine particles, and, depending on the application, sparks. For this reason, extraction should not be considered as an afterthought but should be part of the process planning from the very beginning. Video on the application: https://youtube.com/shorts/UWRYhdcqdDw?feature=share What happens during laser cleaning? In laser cleaning, concentrated energy strikes the surface. The laser dissolves, vaporizes, or removes unwanted layers such as rust, oxides, deposits, or paint residues. The emissions produced are primarily determined by the material, coating, process parameters, and laser source. Therefore, each application must be considered individually. Stainless steel, tool steel, aluminum, painted components, or oxidized surfaces can generate different particle and gas loads. TBH describes laser processes in material processing as applications in which ultrafine particles in the µm and nm range can be generated. This is precisely why efficient extraction and filtration systems are important for occupational safety. Extraction for laser cleaning begins with process planning Extraction for laser cleaning should be considered right from the start when planning the laser process. This is because as soon as the laser removes residues from the metal surface, emissions are generated directly in the processing area. Depending on the process, these include smoke, fine particles, ultrafine particles, and in some cases sparks. Furthermore, these emissions can spread throughout the work area or settle on machines, components, and surfaces if they are not captured early on. That is why it is not just the filter and extraction system itself that matters. The capture element, the air flow rate, the filter configuration, the airflow path, and any accessories must also be suited to the application. Extraction in laser cleaning: Why capture at the source matters The most important factor in the extraction of laser emissions is proximity to the source. The sooner the extraction system captures smoke and particles, the lower the likelihood that they will spread throughout the work area. The DGUV also points out in its guidance document on cleaning and stripping with laser radiation that hazards from hazardous substances generated during these activities may arise. The guidance document specifies a functional, efficient extraction system and recommends capturing ablation products as close as possible to the source. This applies particularly to open or partially open applications. An extraction hood, a suitable capture element, or an application-specific enclosure can capture the emissions where they are generated. What role do smoke, fine particles, and sparks play? The video clearly shows that visible smoke is produced when removing residues from metal surfaces. At the same time, fine and ultrafine particles can be generated that are not reliably detectable to the naked eye. When it comes to dust and particle emissions, therefore, it is not just the visible cloud of smoke that matters. Particle size, composition, concentration, and duration of exposure are also critical. The BGHM recommends that for activities involving hazardous substances, information about the hazardous substances generated should be obtained, limit values should be taken into account, and, if extraction is necessary, the hazardous substance should be captured as directly as possible at the point of generation. When a spark arrester may be useful Additionally, sparks can be generated during laser cleaning. This depends, among other things, on the surface, energy input, and process control. For the application shown, we therefore recommend a spark arrester as well. TBH offers suitable spark arresters as accessories for the TFS series. However, the appropriate model depends on the specific air flow rate and the particular application. Therefore, the spark arrester should always be considered in conjunction with the filter and extraction system. Why a standard vacuum cleaner is not a suitable solution A simple vacuum cleaner is not sufficient for professional laser processes. Laser cleaning does not produce ordinary contamination such as chips on the floor. Instead, airborne emissions are generated directly during the process. These emissions must be specifically captured, routed, and filtered. This is why a coordinated extraction concept is required. This includes, among other things: appropriate capture directly at the source suitable airflow appropriate filter equipment for particles and, if necessary, gaseous components safe routing of process air assessment of sparks, hot particles, and fire risks maintenance and filter replacement concept This is precisely why the extraction system for laser cleaning should always be designed to suit the material, the surface, and the process. TBH Filter and Extraction Systems for Laser Processes TBH develops and manufactures modular filter and extraction systems for industrial applications. For laser processes, TBH designs systems and accessories based on the specific process. Several factors come into play here: material, emission volume, capture conditions, air flow rate, filter equipment, and potential spark generation. Therefore, it is not sufficient to consider just a single component. You can find more information on laser fume extraction here: Laser fumes - TBH GmbH Filter- und Absauganlagen Example: TFS 250 with suitable capture For applications such as laser cleaning on metal surfaces, a TFS filtration and extraction system with a suitable extraction hood can be a practical solution. The key factor here is the interaction between capture, airflow, filter technology, and accessories. The system must not only move air but also capture the resulting emissions as directly as possible at the source and filter them reliably. You can find more information about the TFS 250 here: https://www.tbh.eu/produkt/tfs-250/ In this application, we also recommend the use of a spark arrester. We will work with you to determine which model is best suited based on the specific process. Conclusion: Laser cleaning and extraction go hand in hand Laser cleaning can offer many advantages in manufacturing, toolmaking, and surface pretreatment. At the same time, the process generates emissions that should not be allowed to enter the work area uncontrolled. Anyone using laser cleaning professionally should therefore plan for extraction early on. A well-planned extraction system for laser cleaning helps capture smoke, fine particles, and process-related sparks directly at the source. How do you handle extraction during laser cleaning? Talk to us about your specific application. Together, we’ll determine which filtration and extraction solution is right for your process. FAQs on Extraction for Laser Cleaning What emissions are generated during laser cleaning? Laser cleaning can produce smoke, fine particles, and, depending on the material or coating, gaseous components. Under certain process conditions, sparks may also occur. Why is capturing emissions directly at the source important? The closer the extraction system captures emissions at the source, the less smoke and particles can spread throughout the work area. This provides better protection for employees, machines, and the surrounding environment. Is a spark arrester required for laser cleaning? That depends on the specific process. If sparks or hot particles may be generated, the operator should consider using a spark arrester.   In the application shown here, we recommend a spark arrester. Which extraction system is suitable for laser cleaning? There is no one-size-fits-all answer. Key factors include the material, surface residues, laser parameters, emission volume, capture conditions, and desired airflow.

The company cleans used IT equipment before testing it, refurbishing it, and putting it back on the market. A custom-built TBH DT150 extraction cabinet captures dust and gaseous emissions directly at the workstation. AfB social & green IT combines IT refurbishment with social impact. The company professionally refurbishes end-of-life business IT and mobile devices while simultaneously creating skilled jobs for people with disabilities. The process follows a clear cycle: AfB performs certified data destruction, refurbishes the hardware, performs technical testing, and then returns it to the usage cycle. Cleaning used IT devices as a key process step A central step in refurbishment is cleaning the devices. Dust, abrasion, and other residues often accumulate in used laptops, PCs, and peripherals. Depending on the level of contamination and the cleaning agent used, vapors or gases may also be generated. AfB uses a TBH DT150 extraction cabinet for this step. TBH manufactured the system as a custom version with a larger cabinet to ensure it fits the cleaning process perfectly. Direct capture of dust and gases at the workplace The extraction cabinet in IT refurbishment creates a clearly defined cleaning zone. Employees clean the devices directly inside the cabinet. The system captures dust and gaseous particles immediately within the work area before they enter the room air. This is precisely what makes the process effective. Cleaning remains controllable, the workplace stays cleaner, and the burden on employees is reduced. TBH developed the DT series for laboratory and workshop processes. It features an adjustable protective screen, various attachments, and application-specific filter configurations. Depending on the process, particle filters and activated carbon filters are used. Filter technology for particles and gaseous substances The individual filter stages perform different tasks. The particle filter reduces fine dust particles. The activated carbon filter adsorbs gaseous substances and odors. In this way, the system supports a clean and stable cleaning process. For the DT100/DT150 series, TBH specifies, among other things, an effective air flow rate of 1,000 m³/h, a maximum static pressure of 1,500 Pa, an H13 particle filter, and 65 liters of activated carbon filter volume. For custom configurations, the technical specifications may vary depending on the project. In addition, a differential pressure gauge indicates the condition of the filters. If the differential pressure rises, the team can detect increasing filter saturation early on and better plan for filter replacement. Technical protective measures over personal protective equipment For AfB, this means: The company integrates cleaning technically into the overall process rather than merely ensuring it organizationally. According to customer experience, this allows work to be performed in this application without additional respirators. However, the operational risk assessment always remains decisive. From a technical standpoint, this approach aligns with the STOP principle. Technical protective measures take precedence if they sufficiently reduce the hazard. The extraction cabinet in IT refurbishment supports precisely this approach. Clean processes for the reuse of IT devices At AfB, cleaning is followed by technical testing, any necessary repairs, and upgrades. Only then are the devices returned to sale to private and business customers. In this way, the extraction technology supports a clearly defined refurbishment process. It improves working conditions in the cleaning area, protects employees, and stabilizes the process chain for the reuse of used IT equipment.

Anything that remains in the air is inhaled, spreads throughout the work area, and settles on machines and components. Clean air is therefore not just a matter of occupational safety: it is a factor in productivity and quality. Clean air has a triple effect: human beings, processes, products Protecting health: Less polluted air means better working conditions – especially where emissions occur on a permanent basis. Stabilizing processes: Less deposits and contamination, less cleaning effort, fewer disruptions. Reducing costs: When pollution levels fall, in the best case scenario the proportion of absenteeism-related complaints also falls – and with it direct and indirect costs. Absenteeism costs money – and respiratory diseases are a major factor The BAuA estimates a total of 881.5 million days of incapacity to work for 2024. This results in an economic loss of €134 billion in lost production and €227 billion in lost gross value added. Within the diagnosis groups, “diseases of the respiratory system” (ICD J00–J99) account for 159.2 million days of incapacity to work (18.1%) €24.3 billion in lost production €41.0 billion in lost gross value added Important for classification: These BAuA figures show the magnitude of incapacity for work and costs – they do not say that respiratory diseases are caused by poor workplace air to this extent. However, they illustrate why prevention and effective air technology are economically relevant. Where emissions typically occur Depending on the industry and process, emissions occur, for example, during: Grinding, cutting, milling (fine dust) Welding, soldering (smoke/particles) Laser and thermal processes (aerosols) Chemical/adhesive processes (vapors/VOCs) Additive/powder handling (dust, particles) The source is crucial: extraction before everything spreads The earlier emissions are captured, the more effective the overall system is. In practice, this means: 1) Capture at the source Source extraction or enclosure instead of “cleaning the air afterwards.” 2) Appropriate filtration Particles, smoke, vapors/aerosols require different filter and safety concepts. 3) Maintain long-term effectiveness Air flow rate, filter condition, and maintenance logic determine the real effect in everyday use. Quick check: 5 questions that provide immediate clarity Where do the emissions originate – and how far do they “travel”? Are they captured at the source or only in the room?

The TBH TFS series provides reliable protection with W3 and HEPA H14 SafeLine filters.", "fulltext": "Laser cleaning often appears to be a clean process. In occupational safety, however, appearance is not the deciding factor. The relevant question is what the process releases into the air. Published research shows that laser cleaning can generate airborne aerosols, including fine and submicron particles. That matters because exposure control has to address not only the laser beam itself, but also the contaminants created during material removal. What the research shows The core takeaway is straightforward: laser cleaning should not be treated as an emission-free process. Aerosol formation depends on the substrate, the layer being removed, and the process setup. As a result, the hazard profile can vary significantly from one application to another, even when the same laser technology is used. For occupational safety practice, that is highly relevant. Fine and ultrafine particles are exactly the kind of emissions that should be captured as close as possible to the point of origin. Why the topic should be viewed internationally For an English-language audience, the topic should not be framed only through one national rule set. A more useful structure is to begin with internationally recognized machine-safety and process-safety standards, then add the regional legal frameworks that shape employer obligations in practice. That approach is more relevant for readers in Europe, North America, and third countries that work with ISO-based safety concepts or follow comparable risk-assessment logic. Which international guidance matters At international level, the ISO 11553 series is a key reference for laser processing machines. ISO 11553-1 addresses hazards generated by laser processing machines, including radiation hazards and hazards generated by materials and substances. ISO 11553-2 specifically addresses hand-held or hand-operated laser processing devices and focuses on hazard analysis, risk assessment, and protective measures. For laser cleaning, that framing is important because the safety question is not limited to beam exposure. It also includes what the process generates in the air. This makes an international standards-based reading more useful than a narrow country-by-country view. Why source capture matters For laser cleaning, general room ventilation alone is not a robust control strategy. The more reliable approach is source capture combined with filtration matched to the actual emission profile. In practice, that means the extraction concept should be designed around the real process rather than around the assumption that laser cleaning is “clean.” Relevant factors include the base material, any coating or residue being removed, the expected particle load, possible gaseous emissions, the capture position, airflow, duct routing, and whether cleaned air will be recirculated or discharged. Which U.S. guidance matters For U.S. readers, the relevant framework is typically a combination of OSHA exposure-control requirements, OSHA ventilation guidance, and laser-processing safety standards recognized by OSHA. OSHA points to ISO 11553-2 for hand-held laser processing devices, which makes it a useful bridge between international machine-safety logic and U.S. workplace practice. That is important because hand-held systems used for cleaning and decoating need to be assessed not only for beam hazards, but for the full operating context. In other words, safe use depends on both radiation safety and control of the airborne contaminants generated during the process. Which European guidance matters For European readers, the topic is shaped by several layers. Directive 2006/25/EC covers worker exposure to artificial optical radiation. Directive 98/24/EC covers risks related to chemical agents at work. Where carcinogenic or mutagenic substances are relevant, Directive 2004/37/EC adds another layer of worker protection. For laser cleaning, that means the European reading is also dual: employers have to consider both the optical-radiation hazard and the hazardous substances generated during processing. Safe operation is therefore not only about laser class and shielding. It also requires suitable engineering controls, including capture and filtration where airborne contaminants are generated. A brief Germany note For Germany, DGUV FBHM-139 is the more direct practical reference for hand-held Class 4 laser cleaning and decoating systems. TRGS 528 can still serve as a benchmark for source-capture logic in metal-emission contexts, but in an English-language article it should remain a short Germany-specific note rather than the main framing. Why W3 still matters internationally W3 is not the global legal baseline for laser cleaning, but it remains an important technical reference, especially for readers in Europe and in export markets that compare filtration concepts internationally. According to DGUV, the IFA tests and certifies welding fume extraction devices in accordance with DIN EN ISO 21904-1 and -2, and certified devices may be marked W3. For laser cleaning, W3 should therefore be presented carefully: not as an automatic approval for every process, but as a relevant reference where metallic particulate emissions, recirculated air, or neighboring welding and thermal-processing applications are part of the environment. Its value lies mainly in the filtration and recirculation context, while final suitability still depends on the actual process and risk assessment. Which extraction system is suitable? For laser-related smoke and fume applications, TBH positions the TFS series as an industrial extraction system certified according to DIN ISO 21904 (W3) for laser marking, laser engraving, and automated welding processes. Which configuration is suitable always depends on the specific process. Decisive factors include the material, the surface condition, the emission profile, the required airflow, the duct length, the capture geometry at the source, and whether odors or gaseous components must also be considered. This is especially important in laser cleaning because emissions are influenced not only by the laser, but also by coatings, residues, and the removal mechanism itself. Conclusion The key occupational safety message is simple: laser cleaning is not automatically a low-emission process. A more internationally useful reading combines ISO-based machine safety, source-capture principles, U.S. ventilation guidance, European optical-radiation and chemical-agent requirements, and a process-specific risk assessment. A defensible safety concept therefore starts with the actual process: what is being removed, which contaminants are created, how they are captured, how they are filtered, and whether the selected extraction system is appropriate for that application. FAQ Is laser cleaning an emission-free process? No. Published research shows that laser cleaning can generate airborne aerosols, including fine and submicron particles. Is general shop ventilation enough on its own? No. Source capture is the more robust approach. Which guidance is most relevant internationally? For an international English-language audience, the most useful starting point is ISO 11553-1 and -2, then the applicable regional framework such as OSHA in the U.S. or the EU directives on artificial optical radiation and chemical agents. What does W3 mean? W3 identifies welding fume extraction devices that the IFA of the DGUV tests and certifies in accordance with DIN EN ISO 21904-1 and -2. Does a published study replace a site-specific risk assessment? No. A study is an important technical indication, but it does not replace a process-specific occupational risk assessment for the actual workplace, materials, and extraction concept.

In many processes, particle filtration alone is not sufficient. This is precisely where activated carbon complements the filter system – for clean process air and greater protection in the working environment. At TBH, the focus is always on the goal: triple protection for human beings, the environment, and machines. What does adsorption with activated carbon mean? In adsorption (with a “d”), molecules accumulate on a surface. This is the key difference to absorption (with a “b”), in which substances “penetrate” a material. In short: Adsorption with activated carbon = molecules adhere to the surface of the activated carbon. Why can activated carbon bind so many substances? Activated carbon is extremely porous. These pores create a very large internal surface area. And the larger the surface area, the more molecules can be adsorbed. In practice, this means: Many pores → large surface area Large surface area → extensive contact with air More contact → better binding of gaseous substances This makes activated carbon particularly suitable for dealing with odors, vapors, and VOCs. Physical adsorption: No chemistry, pure physics In many applications, activated carbon works via physical adsorption. In this process, molecules adhere to the activated carbon surface through weak attractive forces (Van der Waals forces). Important for classification: There is no chemical reaction. The bond is physical. The effect depends on the type of substance, concentration, temperature, humidity, and contact time. Where is adsorption with activated carbon used? Adsorption with activated carbon is used wherever gaseous emissions are relevant—for example: Gases & vapors from cleaning and dissolving processes VOCs during gluing, coating, or in plastic-related processes Odors that are disruptive in the work area or cause complaints Smoke components when the gas phase plays a role Typical industries: Paint shop / coating Laboratory / chemical-related processes Metal processing (e.g., cleaning vapors) Food industry (depending on the process) This is what a sensible filter chain looks like In extraction technology, activated carbon is often an additional filter stage – usually after particle filtration. This makes sense because dust can contaminate the activated carbon. Typical structure: Prefilter (protection of subsequent stages) Particle filter (e.g., fine dust/HEPA – depending on the process) Activated carbon filter (gas phase: VOCs, vapors, odors) This keeps the activated carbon effective for longer and improves its service life. Advantages of adsorption with activated carbon When activated carbon is designed to suit the application, you often benefit from: ✅ Broad spectrum of pollutants (especially organic vapors/VOCs) ✅ Noticeably better air quality in the working environment ✅ Greater occupational safety when the gas phase is relevant ✅ More stable processes, e.g. in applications where odors or measured values are critical What influences the performance of an activated carbon filter? The following points are crucial for adsorption to work reliably: Type of substance (not every substance adsorbs equally well) Concentration (high load = faster saturation) Volume flow (amount of air per time) Contact time (how long the air flows through the medium) Temperature & humidity (can influence adsorption) Pre-filtration (dust reduces service life) Practical tip: If you want to evaluate the activated carbon stage, the substance/process, type of emission, volume flow, and your target (odor, VOC, measured value) are often sufficient. When should you change the activated carbon filter? An activated carbon filter does not “fill up” visibly like a dust filter. Therefore, a clear maintenance approach is important. Typical signs are: Odor despite the system being in operation Rising measured values (internal/external) Maintenance interval reached (TBH recommends at least once a year – shorter depending on the application) Important: Many systems do not monitor activated carbon separately on the display. That is why activated carbon replacement should be included in your maintenance plan – including documentation. Quick check: Is adsorption with activated carbon suitable for your application? Adsorption with activated carbon is particularly useful if at least one of the following points applies: Are VOCs or solvent vapors produced? Is there odor pollution that causes annoyance or complaints? Do measurement values have to be kept stable? Is the gas phase relevant (not just particles)?

An additional layer on the filter surface facilitates cleaning, stabilizes the extraction performance, and significantly extends the service life.", "fulltext": "When filtering sticky, moist, or very fine dusts, conventional filter cartridges quickly reach their limits. Precoating protects the filter surface with an additional layer, facilitates cleaning, and significantly extends the filter’s service life. What is precoating? In precoating, an additional protective layer is applied to the filter cartridge before the actual filtration process. This layer consists of a suitable precoating agent (e.g., a finely metered powder) that distributes evenly across the filter surface. Dust particles first settle on this precoating layer and do not penetrate directly into the pores of the filter material. This keeps the filter protected. The accumulated particles can be removed from the filter surface with bursts of compressed air, ensuring that the filter itself remains clear and functional for longer. In short: Precoating = a protective layer for the filter cartridge that reduces wear and simplifies cleaning. Why do filter cartridges clog so quickly—especially with sticky dusts? Many applications generate critical dust emissions, for example: sticky dusts from resins, adhesives, or coatings moist dusts, such as in processes involving coolants or lubricants very fine dusts that penetrate deep into the filter pores Without precoating, the following happens: The particles become lodged directly in the filter material. Sticky or moist components clog the pores. The filter cartridge becomes saturated quickly, and the differential pressure rises. Extraction performance decreases, posing a risk of process disruptions and downtime. Result: frequent filter changes, increased maintenance effort, and rising operating costs. How does precoating work in practice? The precoat process typically involves several steps: Application of the precoat layer Before the process starts, the precoat agent is metered into the intake air. This forms an uniform protective layer on the filter cartridge. Filtration through the precoat layer During filtration, the particles collide with this layer and deposit there instead of penetrating directly into the filter material. Cleaning via compressed air pulses After a defined filtration cycle, a cleaning process begins, for example using compressed air pulses. The precoat layer detaches along with the adhering particles. The fine dust falls into the system’s dust container. Application of a new layer Subsequently, a precoat agent is added again, so that a new protective layer forms on the filter cartridge. This cycle is repeated at regular intervals. This ensures that the filter cartridge remains functional significantly longer, even with high dust volumes or when dealing with wet or sticky dust. What are the benefits of precoating? Operators of filter and extraction systems benefit from several advantages: significantly longer filter service life Since the actual filter cartridge is protected from direct contact with critical dusts, the filter material ages more slowly. → Fewer filter changes, less downtime. More stable extraction performance Due to the regular cleaning of the pre-coating layer, the pressure drop across the filter stage remains constant for longer. → The system can be operated at constant performance for a longer period of time. Better cleaning for sticky dusts Many sticky dusts adhere very strongly to filter media and are difficult to remove. With precoating, it is not the filter itself that is cleaned, but the precoat layer. → Cleaning is more efficient and gentler on the filter cartridge. Resource Conservation & Sustainability Fewer filter changes mean: lower material consumption less disposal effort less downtime, more efficient use of the system This aligns with the triple protection of human beings, the environment, and machinery that TBH stands for. When is the use of pre-coating particularly beneficial? Pre-coating is especially worthwhile in applications where: sticky or resinous dusts are generated (e.g., resins, adhesives, coatings) moist or clinging dusts occur (e.g., during mixing or transfer processes) very high dust loads with fine particles are present a long, stable filter service life is required, e.g., in automated production lines In combination with cleanable filter cartridges, even difficult-to-handle dusts, such as sticky or moist particles, can be reliably captured. Precoating in conjunction with TBH filter and extraction systems TBH relies on modular filter and extraction systems that can be combined with suitable filter modules and, if necessary, with precoating, depending on the process. The benefits for you: Adaptability to different processes and dust types Reliable separation even with critical dusts Predictable maintenance intervals instead of unplanned downtime Especially in industrial applications where high-quality machinery, sensitive products, and employee health must be protected, the combination of proper filter technology and precoating is a key component for stable and safe processes. Conclusion: Small layer, big impact Pre-coating is a seemingly small measure with a big impact: It protects the filter cartridge from clogging. It facilitates cleaning. It ensures longer service life and stable extraction performance—especially with difficult dusts. In this way, precoating makes a decisive contribution to making workplaces safer, protecting machinery, and reducing emissions—in line with the TBH slogan: Triple protection for human beings, the environment, and machinery.

Starting in March 2020, the faculty administration reorganized clinical procedures to prepare for the resumption of clinical instruction with students. A key objective was to reduce potential exposure risks. This applied particularly to students at various stages of their training. Extraoral suction during aerosol-generating procedures Following discussions and based on regulatory guidelines, the faculty introduced extraoral suction devices from TBH. The devices are used during aerosol-generating procedures. The goal was clear: to capture aerosol residues directly at the source. TBH clearly defines the use of these devices in a medical setting. The systems are not sold there as medical devices, but as accessories for extracting air directly during laser procedures on patients; there is no patient contact. What stood out in everyday use The customer testimonial highlights several points that are important in daily clinical practice. The devices are powerful. At the same time, they remain comparatively quiet. Operation is also simple. This helped the team and the students in their daily work. Another positive aspect was that the devices support workflow at the treatment station. According to feedback, they helped the students maintain better posture. Cleaning after each patient could also be easily integrated into the workflow. Maintenance requirements remained low. The TBH documentation on the medical environment also emphasizes that spot-specific cleaning can reduce the cleaning effort and that a structured filter change is part of the hygiene concept. Customer Testimonial from the University of Malta “The COVID-19 pandemic has brought about many changes in our daily operations at the Faculty of Dentistry at the University of Malta. Since the start of the pandemic in March 2020, the faculty administration has begun reorganizing our clinical protocols to be prepared for the resumption of clinical courses with our students. One of our main concerns was to reduce potential exposure risks for our students, who are at various stages of their training. Following discussions and on the recommendation of health authorities, the faculty introduced TBH’s extraoral suction devices, which are to be used during all aerosol-generating procedures. The goal was to capture all aerosol residues generated during dental procedures directly at the source. We have found the devices to be very effective in many ways—they are very powerful without generating excessive noise. In fact, a high-speed handpiece makes more noise than the TBH devices. They are also very easy to use. Another benefit we observed in the clinics was that the device helped students maintain proper posture during dental treatments, as the TBH device prevents poor posture. Patients of all ages have no objections to the device, and some have even noted that it made them feel safer. The dental assistants believe that the devices not only provide safety for students and patients but also for themselves as part of the dental team. They require minimal maintenance and are easy to clean after each patient. The filters are replaced weekly to ensure maximum efficiency. In summary, we are very satisfied with the TBH devices and highly recommend them for dental practices.” The statement is from Prof. Nikolai Attard, Head, Department of Oral Rehabilitation and Community Care, Faculty of Dental Surgery, University of Malta. Conclusion The feedback from Malta highlights what matters in sensitive environments. Key factors include ease of use, seamless integration into daily practice, and precise capture during aerosol-generating procedures.

This produces surgical smoke gases (“laser plume”), which can consist of a mixture of fine and ultrafine, respirable particles and biological components as well as gaseous substances. Scientific studies show that a significant proportion of the particles contained in laser smoke are respirable (e.g., JCAD overview of laser-generated airborne contaminants 2024). In individual studies, viral DNA—such as HPV in HPV-associated lesions—has also been detected in laser plume or surgical smoke (including Palma et al., studies from Germany and other European centers on LEEP procedures, and a recent review in GMS Hygiene and Infection Control 2024). This results in potential, recurring exposure for doctors and medical professionals in their daily practice. Occupational safety and health framework in Germany The following apply in particular to medical facilities: TRBA 250 – Biological agents in healthcare and social welfare Hazardous Substances Ordinance (GefStoffV) DGUV Rule 109-002 – Activities involving exposure to surgical smoke These regulations focus on technical protective measures to minimize potential exposure. The central principle is to capture emissions as close as possible to the source. The practice operator remains responsible for carrying out a risk assessment. Why technical extraction measures are useful for compliance with occupational safety in everyday dermatological practice Surgical smoke consists mainly of fine and ultrafine particles that can spread throughout the room. Depending on their design, positioning, and maintenance, local extraction systems can help to reduce the particle concentration in the immediate working environment. The following factors are crucial: Capture directly at the point of application Suitable filter technology Regular maintenance Professional integration into the treatment process The TBH Health series – developed for medical applications The TBH Health series was developed specifically for use in dermatological and aesthetic treatment rooms. It enables: Targeted capture of laser smoke at the point of origin Integration into existing practice structures Support in the implementation of technical occupational safety measures As a German manufacturer with over 30 years of experience in filter and extraction technology, we develop solutions that are tailored to the requirements of medical facilities. Why is occupational safety important in everyday dermatological practice? Ablative CO₂ laser therapies are an established procedure in dermatology. The surgical smoke produced is classified as relevant to occupational safety in German regulations. Technical extraction measures can help minimize potential exposure, depending on the individual application.

Fine dust particles pose a particular danger, as they are generated in many industrial processes—such as laser cutting, welding, or the processing of metals and plastics. While fine dust from road traffic primarily concerns cities and municipalities, the situation in industrial production is fundamentally different: here, fine dust is generated directly at the workplace, affecting employees, machines, and the production environment.This is exactly where modern extraction and filtration systems come into play. They reduce particle exposure in a targeted manner and thus make an important contribution to protecting people, the environment, and machinery. Tumors: Benign or Malignant? The term tumor simply means “swelling” or “growth.” It describes a tissue change in which cells grow where they normally should not. In general, two types are distinguished: Benign Tumors Benign tumors grow slowly, displace surrounding tissue, and remain clearly defined. They do not invade healthy tissue and do not form metastases. Malignant Tumors Malignant tumors, by contrast, grow rapidly and aggressively. They destroy surrounding tissue and can spread throughout the body.Particularly dangerous are metastases: tumor cells travel via the bloodstream or lymphatic system and form new growths in other parts of the body. What Is Cancer? Cancer is always a malignant tumor. It develops when faulty cell divisions are no longer recognized or eliminated by the immune system. Common forms include so-called carcinomas, which originate from epithelial tissue—for example, lung cancer. Cancer is especially dangerous because it: destroys healthy tissue, can spread throughout the body via metastases, and is often detected only at a late stage. How Does Cancer Develop in the Body? The human body renews millions of cells every day. Old cells die off and new ones form through cell division. DNA and its genes control this process. About 20% of our genes serve a control function. These so-called guardian genes monitor cell division and prevent errors. If mutations—changes in genetic material—occur and no repair mechanism intervenes, cancer can develop. The situation becomes particularly critical when the guardian genes themselves are affected. In this case, the body loses control over cell division.As people age, the risk of cancer increases because more genetic alterations accumulate over time. Causes and Risk Factors for Cancer Cancer rarely results from a single cause. In most cases, several factors interact. In addition to genetic influences, environmental and occupational conditions play a decisive role—especially in industrial production: Ionizing radiation, for example from certain laser processes Mutagenic chemicals released during material processing or cleaning Fine dust from production processes such as welding, laser cutting, or grinding—one of the most critical risk factors Smoking and external environmental factors, which also contribute but are independent of the industrial context Industrial fine dust poses a particularly high risk because its particles are extremely small and can penetrate deep into the respiratory system. Conclusion: Effectively Reducing Cancer Risks from Fine Dust in Production Not every tumor is cancer—but every cancer is a malignant tumor. Cancer develops when faulty cell divisions remain uncontrolled over time. Industrial fine dust significantly increases this risk, as it penetrates deep into the lungs and can cause long-term health damage. If fine dust is generated as a by-product in your production processes, early action is essential. Modern extraction and filtration systems protect employees from carcinogenic particles, reduce environmental impact, and help preserve machinery. ➡️ Contact our experts for individual consultation—together, we will find the right solution for clean and safe air in your production environment.

They occur both naturally and as a result of human activity (anthropogenic). Anthropogenic dust is particularly critical, as its chemical composition can be more harmful to health and the particles can penetrate deep into the respiratory tract. In order to better classify the health risks of airborne dust and particulate matter, airborne dust is classified according to its size. Since the particles do not have a uniform shape, the so-called aerodynamic diameter is used. This describes how large a particle would be if it had a standardized density and spherical shape. Classification of airborne dust according to particle size Designation Aerodynamic diameter Special feature/effect Ultrafine particles < 100 nm Can pass through cell membranes and enter the bloodstream PM2.5 (fine dust) < 2,5 µm Penetrates deep into the lungs, increases the risk of cardiovascular and respiratory diseases Coarse particles > 2,5 µm Tend to settle in the upper respiratory tract PM10 < 10 µm Cause irritation of the respiratory tract, but are partially intercepted Anthropogenic vs. natural – where does the dust come from? Natural airborne dust: pollen, sand, sea salt, or volcanic ash. Anthropogenic airborne dust: Produced by traffic, industry, combustion processes, or production technologies such as laser processing or welding. Industrial processes in particular produce particles that contain not only airborne dust but also substances that are hazardous to health. This is why a suitable filter and extraction system is crucial here. Conclusion: Not all airborne dust is the same While natural dust usually only occurs locally, particles generated by humans can have long-term effects on health and the environment. Classification according to particle size – from ultrafine to PM10 – helps to better assess the risk and take appropriate protective measures. With an optimally adapted extraction system, airborne dust can be reliably captured and exposure in the workplace significantly reduced.

Many production processes generate dust, particles, and aerosols that must be reliably filtered out of the air. However, not every dust filter is suitable for every application. Knowing the differences allows you to select the right filter solution and thus optimally protect employees, the environment, and machines. This article provides an overview of the most common types of dust filters and explains what they are best suited for. Aluminum filter (G3) The aluminum filter consists of aluminum wire mesh and serves as a coarse dirt filter. ✅ Typical areas of application: Hair Lint Coarse dust With the G3 filter standard, it offers robust basic separation and is often used as the first filter stage. Pre-filter mat (F5) The pre-filter mat is a fine dust filter with very low capacity. It is suitable for simple applications and is often used as a cost-effective alternative to bag filters. Filter standard: F5 Application: Separation of small amounts of fine dust Advantage: Inexpensive and easy to replace Bag filter (F5–F6) The bag filter is a saturation filter and can also serve as a pre-filter. Its large filter area makes it significantly more efficient than the pre-filter mat. ✅ Advantages: Long service life Suitable for high dust loads Flexible application options With filter standards F5 to F6, the bag filter is a reliable choice for applications with increased dust exposure. Z-line filter (F6–F7) The Z-line filter owes its name to its jagged shape. This gives it a high capacity and means it saturates less quickly. Filter standard: F6–F7 Application: Separation of fine dust Advantage: Longer service life and lower maintenance requirements Particle filters (HEPA/ULPA range) Particle filters are used for particularly demanding applications. They can reliably separate extremely fine particles such as smoke, oil mist, or nanoparticles. Typical application: Laser processes, welding fumes, chemical emissions Highest filter performance (e.g., HEPA H13/H14 or ULPA) Guarantee virtually particle-free air Conclusion: Selecting the right filter The choice of the right dust filter always depends on the type and quantity of particles. While aluminum filters reliably separate coarse dirt, particle filters are indispensable for the finest emissions. Tip: Often, a combination of several filter stages is the most efficient solution – starting with a coarse filter, through fine dust filters, to particle filters for the highest requirements. This not only ensures the health of your employees, but also the service life of your machines and contributes to environmental protection." }, { "title": "Laser Cleaning in Practice: When Extraction Becomes a Critical Success Factor", "url": "https://www.tbh.eu/en/blog/laser-cleaning-in-practice-when-extraction-becomes-a-critical-success-factor/", "type": "blog", "last_modified": "2026-04-21", "summary": "Laser cleaning is considered a clean process—but this article explains what emissions are generated during the process and why exhaust extraction is crucial for occupational safety, process reliability, and clear approvals.", "fulltext": "You are using Laser Cleaning – or planning to.The process works, the results are convincing, and the technology is considered clean, efficient, and economical. Precisely for this reason, one aspect is often addressed too late: the emissions generated during the process. No matter how established Laser Cleaning is in your company: the process is not emission-free. And this is exactly where the real challenge begins for production, EHS, and process owners. A Clean Process – with Real Emissions Laser Cleaning removes material thermally. What disappears from the surface does not simply vanish, but enters the surrounding air – often in the form of: ultrafine particles metal oxides residues from coatings material-specific decomposition products In practice, it becomes clear:Depending on material, coating, and process parameters, emissions arise that are neither visible nor clearly noticeable, yet still relevant. What cannot be seen is often underestimated. Why Laser Cleaning Without Extraction Becomes an Issue Many users encounter the same situation:The process runs smoothly, but questions arise – from EHS, occupational health, or management: What are our employees actually breathing in? Have the emissions been assessed? Is general ventilation sufficient? What happens with coated or unknown materials? At this point, it becomes evident: without extraction, there is no solid answer. Not because Laser Cleaning is unsafe –but because emissions without technical capture cannot be controlled. Occupational Safety and Responsibility: Expectations Are Clear Regardless of the technology, one principle always applies: Emissions must be captured directly at the source. Laser Cleaning is no exception. Even if: no chemicals are used no blasting media are required the process is considered modern and “clean” As soon as fine dust, metal oxides, or process residues are generated, the following apply: risk assessment requirements workplace exposure limits technical measures take priority over organisational ones Without extraction, the process remains difficult to justify. With extraction, it becomes manageable. Extraction in Laser Cleaning: Not an Add-On, but Safeguarding In practice, extraction is often discussed only when: processes are scaled up multiple workstations are involved EHS or management raises concerns Time and again, the same conclusion emerges: Extraction does not only ensure clean air – it provides certainty in internal discussions. It delivers: controlled emissions reproducible conditions clear responsibilities acceptance from EHS and management In short: extraction makes the process defensible within the organisation. Typical Real-World Scenarios Many companies face similar challenges: Laser Cleaning is used in mobile applications materials change frequently coatings are not always clearly defined processes take place in existing production environments In these cases, extraction determines whether Laser Cleaning is: professionally integrated or perceived as an “uncertain special process” Conclusion: Anyone Responsible for Laser Cleaning Should Plan Extraction There is no doubt that Laser Cleaning works.The decisive question is how safely, sustainably, and transparently the process is implemented. A suitable extraction solution: protects employees stabilises processes facilitates internal approvals and supports sound investment decisions Put simply:extraction provides the arguments needed to justify Laser Cleaning internally. ➡️ If you use Laser Cleaning and want to assess extraction properly, speak with our experts.

For us, this underscores our commitment to clear processes, reliable procedures, and a systematically structured quality management system. For our customers and partners, the extended certification provides up-to-date and verifiable proof that TÜV SÜD Management Service GmbH has re-audited our quality management system. What does DIN EN ISO 9001:2015 actually say? ISO 9001 defines the requirements for a quality management system. It describes how a company systematically organizes, monitors, and develops quality. It is not about the certification of a single product, but about the processes and structures within the company. ISO itself also states that the standard creates a framework for reliability, clarity, and continuous improvement without prescribing in detail how a company must operate. (iso.org) Who audits ISO 9001 certification? ISO itself does not issue certificates. This task is performed by external certification bodies. In the case of TBH, this is done by TÜV SÜD Management Service. TÜV SÜD lists both the certification of management systems and the associated DAkkS accreditations on its official website. DAkkS, the German Accreditation Body, acts as the national accreditation authority in Germany and assesses the competence of such bodies. (iso.org, tuvsud.com) Why does ISO 9001 certification have to be renewed regularly? Quality management is not a one-time project. Companies continue to develop processes, requirements change, and evidence must remain up to date. This is precisely why certifications work with terms and recurring audits. ISO explicitly describes certification as external evidence that an organization meets the requirements of ISO 9001. This proof only retains its value if companies renew it regularly, thereby demonstrating that their quality management system continues to meet the requirements. (ISO 9001 explained) Key Takeaways TBH GmbH has extended its certification according to DIN EN ISO 9001:2015 until 2029 TÜV SÜD Management Service GmbH has re-audited the quality management system of TBH GmbH ISO 9001 evaluates a company's quality management system, not an individual product The extended certification confirms that TBH GmbH continues to have regulated processes and structured quality management" }, { "title": "Outside Germany", "url": "https://www.tbh.eu/en/outside-germany/", "type": "page", "last_modified": "2026-04-10", "summary": "To view the contact addresses, please select your country: USA, Canada, Mexico TBH North America, Inc.Daniel Galyean81 County Road 423USA – Killen, AL 35645 Telephone: +1 (256)667-0730E-mail: daniel.galyean@tbh.eu Australia OPIRA Pty Ltd.Opira QueenslandBrisbane Office (Headquarter)32 Dividend StMansfield, Qld 4122 Opira VictoriaMelbourne Office25 Graham RdClayton South, Vic 3169 Opira Western AustraliaPerth Office1/194 Canning HighwayEast Fremantle WA […]", "fulltext": "To view the contact addresses, please select your country: USA, Canada, Mexico TBH North America, Inc.Daniel Galyean81 County Road 423USA – Killen, AL 35645Telephone: +1 (256)667-0730E-mail: daniel.galyean@tbh.eu Australia OPIRA Pty Ltd.Opira QueenslandBrisbane Office (Headquarter)32 Dividend StMansfield, Qld 4122Opira VictoriaMelbourne Office25 Graham RdClayton South, Vic 3169Opira Western AustraliaPerth Office1/194 Canning HighwayEast Fremantle WA 6158Telephone: +617 3414 5514E-mail: solutions@opira.com.auWeb: opira.com.au Switzerland ClevairEine Marke der TECHNOROBOT AGBischofszellerstrasse 77CH-9200 GossauTel. +41 (0)71 505 15 15Fax +41 (0)71 505 15 16E-Mail: office@clevair.chWeb: www.clevair.ch Austria Kappa Filter Systems GmbHIm Stadtgut A1A – 4407 Steyr-GleinkTel.: +43 7252 21 111E-Mail: office@kappa-fs.comWeb: www.kappa-fs.com Italy TBH ITALIA S.r.l.Matteo Luberto (Area Sales Manager Italia)Tel.: +39 375 6855485E-Mail: matteo.luberto@tbh.eu Belgium/Netherlands/ Luxembourg Omco Air Treatment N.V/S.A.Business Park ‘La Corbeille’Corbeillestraat 102B – 2235 WestmeerbeekTelephone: +32 3 449 58 33E-mail: omco@omco.beWeb: www.omco.be Poland TBH-Polska sp. z o.o.ul.

The TFS series from TBH ensures greater safety, less downtime, and efficient filter performance.", "fulltext": "Extraction technology for laser cleaning and laser welding The TFS series from TBH offers state-of-the-art extraction technology for laser cleaning and laser welding. It ensures greater safety, less downtime, and easy maintenance in industrial processes. Laser cleaning, laser welding, and automated manufacturing processes generate smoke, particles, and other emissions. These must be reliably captured and filtered. The TFS series was developed precisely for this purpose. Why good extraction technology is important A powerful extraction system not only improves air quality. It also increases work safety, stabilizes processes, and helps to avoid downtime. Without a suitable solution, maintenance costs and the risk of downtime increase. Companies therefore need systems that work reliably and are easy to maintain. The TFS series at a glance The TFS series combines reliable filter technology, easy handling, and intelligent monitoring. This makes it an economical solution for industrial applications.

Find out why used filters do not belong in household waste and what companies should bear in mind when disposing of them properly.", "fulltext": "Disposing of used filters is one of those issues in industry and production that is often underestimated. As long as a filter and extraction system is working reliably, the focus is usually on performance, service life, and maintenance. But when it comes to changing the filter, a crucial question arises: How are used filters disposed of correctly? First, the most important basic rule: Used filters do not belong in household waste. This is because when you dispose of a filter, you are not only disposing of a component, but also, under certain circumstances, the pollutants bound within it. Why the disposal of used filters is so important Filters in extraction and filter systems absorb particles, dust, aerosols and, depending on the design, also gaseous pollutants from the process air. What the system removes from the air remains in the filter. This quickly turns a seemingly harmless consumable into a waste material with a particular hazard potential. Whether laser processing, welding, grinding, soldering, decanting processes, or other industrial applications: the composition of the substances bound in the filter always depends on the specific process. This is precisely why caution is required when disposing of filters. Disposing of used filters: Why household waste is taboo Many companies are looking for a simple answer to the question of how to dispose of used filters. The simple answer is: not in the household waste. The reason is understandable. Filters can be contaminated with substances that are hazardous to health or even carcinogenic. In practice, this means that not only the ongoing operation of the extraction system is relevant to safety, but also the moment when the filter is changed and subsequently disposed of. What role does waste code 15 02 02 play in Germany? When companies dispose of used filters, waste code 15 02 02 often appears. It is used to classify contaminated absorption and filter materials and provides guidance on proper disposal. It is important for companies to note that the specific application, i.e., what the filter is actually contaminated with, is always the decisive factor. The classification should therefore always match the respective process and the separated substances. What determines the correct filter disposal? When disposing of used filters, it is important to consider not only the filter type, but above all the process behind it. Among other things, the following factors are decisive: which materials were processed which dusts, fumes, or gases were produced whether the filter is contaminated with hazardous substances which local and operational regulations apply how the filter change was carried out This is precisely why a blanket statement is often not sufficient in individual cases. Typical mistakes when disposing of used filters The filter is treated as normal residual waste This is particularly risky if it is not clear which substances have accumulated in the filter. Contamination is underestimated A filter often looks unspectacular from the outside. However, this says nothing about the danger of the substances it contains. The filter is replaced without a suitable disposal concept Safe operation does not end when the system is shut down. Removal, packaging, and handover to the disposal company must also be considered. Waste classification is not clearly documented If there is no clear internal classification, this creates uncertainty for occupational safety, disposal, and auditability. How companies can proceed safely when disposing of filters Check the pollutant profile of the process Which substances were subjected to extraction? Which materials were processed? This determines how critical the filter contamination may be. Do not store filters in the open Removed filters should be handled in such a way that no unnecessary dust is released. Determine the disposal route in advance A certified waste disposal company should be involved at an early stage, not only once the used filters have already been removed. Document the waste code The classification must match the actual waste and be traceable internally. Consider occupational safety Filter disposal is not only waste management, but also protection of employees, the environment, and process safety. Why filter replacement and disposal must be considered together A common misconception is to view filter replacement solely as a maintenance task. In fact, it is also a safety-related process step. If filters have absorbed high concentrations of pollutants, it is not only the filter technology that determines safety, but also the proper handling of the saturated filter after removal. Conclusion: Disposing of used filters means taking responsibility Disposing of used filters is more than just an organizational obligation. It is about occupational safety, secure processes, and the responsible handling of contaminated filter materials. The most important guidelines for companies are: Do not dispose of used filters in household waste Realistically assess contamination Organize disposal through a certified waste disposal company Clearly document the appropriate waste code Incorporating filter disposal into your safety and disposal concept at an early stage reduces risks and creates clarity for all involved. Would you like to dispose of used filters safely or check the appropriate disposal method for your process?

Why filtering air? Learn more What are reasons to filter air? Clean air is a fundamental prerequisite for occupational safety, process stability, and equipment availability. In many industrial and sensitive applications, emissions are generated during machining, cutting, welding, soldering, grinding, or laser cutting—emissions that can harm employees, disrupt processes, and contaminate machinery. These include dust, smoke, aerosols, vapors, gases, and odors. It is therefore crucial not only that the air is filtered, but also where and how: as close as possible to the source, tailored to the process, material, and environment. Why is air filtration important in industrial workplaces and sensitive applications? In many processes, airborne contaminants enter the work area directly. Without proper capture, they can spread throughout the room and enter the breathing zone of employees. Depending on the substance, particle size, concentration, and duration of exposure, this can increase health risks while simultaneously tightening requirements for occupational safety, risk assessment, and exposure control. Air filtration therefore serves not only to protect employees but also to ensure process stability, maintain a clean work environment, and prevent deposits in equipment, enclosures, and technical components. What pollutants are generated during laser cutting, welding, soldering, grinding, or transfer processes? The type of emissions depends on the process and the material being processed. Welding produces fumes and particulate matter; laser cutting typically produces very fine and ultrafine particles, as well as gaseous decomposition products depending on the material. Soldering produces gaseous components in addition to particles. Grinding, dry processing, or transfer operations can release respirable and alveolar dust. In sensitive medical applications, smoke or a plume is additionally generated. Depending on the application, this may contain chemical and biological components. Therefore, the selection of a filtration and extraction solution should always be process-specific. There is no one-size-fits-all solution for all emissions. Why is capture at the source usually more effective than general ventilation? Contaminants should be captured wherever possible at the point of origin. This prevents them from spreading throughout the room in the first place and significantly reduces their entry into the breathing zone. It is precisely this principle that occupational safety and technical sources in Europe and the U.S. describe as a key measure for reducing exposure. Local capture at the source is therefore more effective in many applications than simply general ventilation of the room. This is especially true when emissions occur at specific points and continuously. The closer the capture system is to the source, the better the spread in the work environment can be limited. Why are general ventilation or room air purification alone often insufficient? General ventilation and supplementary room air measures can be useful. In many applications, however, they are only a supplement and not a substitute for source capture. The reason is simple. If a contaminant is first diluted in the room, it may have already spread throughout the work area beforehand. This is a significant difference, especially in emission-intensive processes. Local capture acts sooner and reduces exposure where it originates. How does air filtration protect not only employees but also processes and machinery? Filtered process air not only reduces the burden on employees. It can also help keep work areas cleaner and protect technical components from deposits. Less dust and smoke in the environment often means less cleaning effort. Enclosures, surfaces, and sensitive components can also be better protected this way. This is particularly relevant in integrated systems, in electronics manufacturing, and in sensitive production environments. There, air quality often has a direct impact on stability, cleanliness, and maintenance requirements. What are reasons to filter air? Invest in the future Air filtration provides protection The initial responses demonstrate why TBH does not view air filtration in isolation, but always takes people, the environment, and machinery into account. Air filtration helps effectively capture emissions at the source, protect employees, keep work environments clean, and ensure stable processes. What limits and regulations apply to air filtration in the workplace? The specific legal situation depends on the country, the substance, and the process. Within the EU, Directive 98/24/EC on chemical agents and Directive 2004/37/EC on carcinogenic, mutagenic, or reprotoxic substances, among others, form important legal foundations. They are implemented at the national level and supplemented by country-specific requirements, guidelines, and limit values. In the United States, depending on the substance and application, OSHA regulations, recognized engineering controls, and NIOSH recommendations apply. Specifically regarding fumes from laser or electrosurgical procedures, OSHA and NIOSH explicitly recommend local exhaust ventilation or a combination of general ventilation and local exhaust ventilation. When is air recirculation possible, and when is exhaust air the better solution? There is no one-size-fits-all answer to this question. Whether cleaned air can be recirculated into the room always depends on the specific application. Relevant factors include material properties, potential gas concentrations, the hazard potential, and nationally applicable requirements. The filter configuration, actual process control, and required documentation also play an important role. In some applications, recirculation is technically and regulatory feasible. In other cases, exhaust air is the safer or mandated solution. Therefore, this decision should never be made in isolation. The risk assessment and the applicable national regulations are always decisive. How do you find the right filter and extraction solution for your specific process? The right solution is not determined by filter class alone. The decisive factor is the interplay of application, material, capture conditions, and operational requirements. Important questions include, for example: What emissions are generated? How fine are the particles? Are there additional gaseous components? How high must the air flow rate be? How can the solution be integrated into the existing process? Added to this are requirements regarding maintenance, disposal, noise levels, and installation location. The question of whether a system should be mobile, integrated, modular, or suitable for sensitive environments is also often decisive. A modular design makes particular sense when requirements are changing or growing. This allows the solution to be better tailored to the specific process and adapted as needed. For which applications is process-integrated air filtration particularly relevant? Process-integrated air filtration is particularly relevant wherever emissions are generated directly within the process. This includes, for example, laser fumes, welding fumes, soldering fumes, dry dusts, transfer processes, plastics processing, as well as cleanroom and controlled environment applications. Capturing emissions at the source also plays a crucial role in sensitive medical or aesthetic applications. In these cases, it is not only about the filtering effect, but also about airflow, integration, and suitability for the respective environment. In the medical field, a clear classification also applies. TBH systems are not sold there as medical devices, but as accessories for extracting air directly during laser treatment on the patient, without patient contact. Why should air filtration be incorporated early in the process planning? The earlier air filtration is incorporated into the process planning, the better the capture, integration, and effectiveness can be tailored to the application. Then airflow, installation space, enclosure, maintenance, filter replacement, noise, and interfaces can be planned sensibly at an early stage. If extraction is only considered at the end, it often has to adapt to conditions that have already been established. This makes effective capture at the source difficult and can unnecessarily complicate later integration. Air filtration is therefore not just a matter of occupational safety. It is also a matter of process safety and technical planning. Key Takeaway Air filtration is most effective when it is planned early on, tailored to the specific process, and implemented as close as possible to the source of the air pollution. In this way, it helps protect employees, keep work environments clean, and reliably support processes. Find the right solution for your process.

Überblick zu Umluft vs. Abluft, W3-Zulassung bei Partikeln sowie Abluftführung oder Sensorüberwachung bei gasförmigen KMR-Stoffen.", "fulltext": "What applies to CMR substances in the workplace? CMR substances (also known as CMRs) are an issue in occupational health and safety where there can be no “gray areas.” This is because as soon as substances are classified as carcinogenic, mutagenic, or toxic to reproduction, the requirements for protective measures, documentation, and operation increase significantly. This article serves as a guide for HSE officers, production managers, and technical purchasing. 1) CMR/CMR explained briefly: What does it stand for? CMR stands for: C: carcinogenic M: mutagenic R: toxic to reproduction (toxic to reproduction) Important for your practice: It is not a question of “a lot or a little,” but rather a substance- and process-related assessment that you, as the operator, must document clearly. 2) Recirculated air or exhaust air? The basic logic behind KMR As a general rule, if process emissions do not pose any particular hazards, recirculated air operation is often possible. However, in the case of CMR substances, guidelines and technical rules generally recommend or require the operator to use exhaust air. In addition, the documentation explicitly states that extracted air containing CMR substances of categories 1A and 1B must not be allowed to enter the breathing air. Practical conclusion: Two questions are central to your decision: Are the emissions particulate or gaseous? Has a sufficient separation efficiency been proven for recirculation mode? 3) Particulate CMR substances: Recirculation only with confirmed separation efficiency (e.g., W3) The following applies to particulate CMR substances: Recirculating air operation only with W3-approved system – otherwise exhaust air. In addition, the following describes how verification is intended to work in practice: In recirculating air operation, the separation efficiency during commissioning must be verified by the operator using a tested procedure. If the verification is insufficient, the filtered air must be discharged to the outside. Alternatively, a type-tested extraction and filter system with a confirmed separation efficiency (e.g., according to DIN EN 60335-2-69 Annex AA or W3) can be used. 4) Gaseous CMR substances: Exhaust air or sensor technology with alarm The following applies to gaseous CMR substances: Exhaust air ducting or monitoring of the filtered air with measuring sensors and signaling when limit values are exceeded. If it is not possible to vent to the outside, the operator must monitorthe AGW at the outlet. Important: Gaseous substances require different filter concepts than pure particles, including the adsorption of gaseous substances with activated carbon granulate and molecular sieves against gaseous pollutants. 5) What does W3 mean – and why is it relevant for CMR? TBH systems are tested in accordance with DIN ISO 21904 (W3) and the IFA confirms the systems (including in the IFA positive list). If you have CMR processes in operation, W3 (or a confirmed separation efficiency in accordance with the relevant standard) is relevant because it concerns verifiable protection during recirculation operation. 6) Checklist for HSE & production: How to structure your assessment To help you reach a reliable decision more quickly internally, follow this sequence: Identify substances & check classification (safety data sheet, internal hazardous substances list, CMR classification). Clarify emission type: particulate or gaseous (or both). Define the operating concept: Exhaust air vs. Recirculating air (if recirculating air: consider verification/standard requirements). Prioritize capture at the point of origin (technical protective measures generally follow the logic: avoid → extraction → ventilation measures → PPE). Plan verification & operating obligations (e.g., testing/maintenance logic, measurement concept) . Update documentation (risk assessment, operating instructions, training). 7) How TBH supports – without unnecessary complexity TBH describes that filter and extraction systems have a separation efficiency according to W3 confirmed by the IFA and can also be used for the extraction of CMR substances. In addition, equipment features are mentioned that are particularly relevant for sensitive processes (e.g., HEPA H13-H14 filters, signaling on the display, volume flow meter, signal module, interface with error evaluation, filter principles such as activated carbon adsorption and molecular sieve). Note: This article is a practice-oriented summary and does not replace a site-specific risk assessment.

This is precisely why explosion protection is not a “nice-to-have,” but a central component of safe process design. At TBH, we understand explosion protection for what it is: consistent protection of human beings, the environment, and machinery. ATEX in practice: Assessing risks, implementing measures As an operator, you are required to assess the risk and define the ATEX zones. In the case of dust, this typically refers to zones 20 to 22, depending on how often and for how long an explosive atmosphere can occur. To turn this obligation into a clean process, you need: a clear assessment of the dust (material data, process conditions), a suitable technical solution, and documentation that describes the entire system in a comprehensible manner. TBH FP 200 ATEX: developed for Zone 21 and higher dust quantities If your process generates large quantities of dry, combustible dust, a robust extraction system tailored to the application is crucial. The TBH FP 200 ATEX systems are designed for this purpose and support stable operation – even in demanding dust situations. Key features: Complies with the requirements of the ATEX Directive (RL 2014/34/EU) Suitable for extraction from Zone 21 – the system must be installed outside the zone Suitable for non-metallic dusts with a minimum ignition energy greater than 3 mJ Important: Whether the system is suitable for your specific application depends on the substance to be extracted and must be assessed individually by you as the operator. Documentation that really helps you: Sample explosion protection document Explosion protection does not end with the system – the interaction between the extraction system and the customer's environment is crucial. That is why you receive a special sample explosion protection document that enables you to assess the entire system in a structured manner and to document the necessary steps in a comprehensible way. In summary If you work with non-metallic, combustible dusts and Zone 21 issues are relevant, a clear three-step approach has proven effective: Assess zones & risks (substance + process) Design suitable ATEX extraction (e.g., FP 200 ATEX) Document the entire system clearly (using the sample explosion protection document as a basis) Would you like to check whether the FP 200 ATEX systems are suitable for your dust and process?

Learn how the two concepts differ and which factors are decisive in practice: material profile, process peaks, ventilation situation, maintenance, and operational safety. Includes checklist.", "fulltext": "Whether laser cutting, welding, soldering, grinding, or decanting: many industrial processes generate particles, dust, aerosols, gases, and vapors. The key question is then: Should the purified air be returned to the room (recirculated air) or discharged to the outside or into a central ventilation system (exhaust air)? This article provides a clear overview—technically understandable, practical, and with a checklist to help you make your decision. As always, the goal is to protect human beings, the environment, and machinery. Recirculated air and exhaust air explained briefly Recirculated air mode means: The extracted process air is filtered and then returned to the room. Exhaust air mode means: The filtered process air is discharged to the outside or fed into a central ventilation system. Both concepts have their merits – the decisive factors are the type of substance, concentration, process risk, standards/specifications, and the overall concept of your ventilation system. When recirculation can be useful Recirculation can offer advantages in practice if the following points are met: Energy efficiency: Heat remains in the building (relevant, for example, during the heating season). Simpler building integration: No additional exhaust air ducting to the outside required (depending on location/planning). Stable room air flow: In some production areas, a constant room air balance is important. It is important to note that recirculated air is only a good solution if the filtration is suitable for the risk assessment and substance profile and if operation (including maintenance/monitoring) is implemented safely on a permanent basis. When exhaust air is often the better choice Exhaust air is often preferred when: Health-hazardous substances are produced or cannot be reliably excluded, Odors/gases/vapors remain relevant even after particle filtration (e.g., solvents), Process peaks occur (short-term high emission rates), or conservative, clearly defined air flow is required. Hazardous substances: What you should consider in your decision The following applies to hazardous substances: The risk assessment is the starting point – and thus also the question of whether recirculation is permissible and sensible at all. A practical example: Particularly strict requirements apply to carcinogenic, mutagenic, or reprotoxic substances (CMR). In this context, it is specified, among other things, that extracted air containing CMR substances of certain categories must not enter the breathing air. Accordingly, depending on the process, exhaust air ducting may be the obvious measure – or a clearly proven separation efficiency and a suitable safety concept may be required. Note: The more critical the substance, the more important it is to have verifiable filter performance, monitoring (e.g., volume flow/filter condition), and a clearly defined approach to maintenance and filter replacement. Technical check: 6 questions you should ask yourself 1) Which substances are actually produced? Particles (dust/smoke), aerosols, gases/vapors – often it is a mixture. In the case of vapors/gases, additional stages (e.g., activated carbon) are often relevant. 2) How high are the emissions – continuously and at peak times? Continuous, cyclical, or with peaks? Peak loads influence dimensioning and operational safety. 3) What is your ventilation situation? Is there central ventilation? What are the supply/exhaust air flows in the room? Recirculated air must not cause the entire system to “run out of sync.” 4) Which standards/specifications are relevant for your process? Depending on the application, requirements for welding fume/laser fume extraction (W3, DIN EN ISO 21904) or dust classes may play a role, for example. 5) How do you ensure operational safety in everyday use? Filter loading, maintenance intervals, condition monitoring, documented procedures – without a reliable routine, even the best technology becomes vulnerable. 6) How important are energy and operating costs in the overall picture? Recirculated air can have energy advantages – exhaust air can offer safety reserves. The overall picture is decisive. Practical examples: typical trends Welding/laser smoke: often high occupational safety requirements; depending on the process, W3-compliant solutions may be relevant. Adhesive, cleaning, decanting, or injection molding processes: vapors/gases may dominate here – exhaust air or multi-stage filtration (including gas phase) is often useful. Dry dust (grinding, deburring, milling): depending on the dust class and quantity, recirculated air may be possible – provided that the filter concept, separation efficiency, and monitoring are suitable. Checklist to take with you If you want to make a quick preliminary decision internally, this short checklist will help: Recirculated air is more suitable if ... the substance profile and limit values have been clearly evaluated, The filter performance is demonstrably suitable for the application, Monitoring/maintenance is reliably organized, And energy efficiency is a key objective. Exhaust air is preferable if ... Hazardous substances/CMR/critical emissions are involved, Vapors/gases play a role, Process peaks occur, Or maximum robustness in occupational safety is prioritized. Conclusion Recirculating air or exhaust air is not a matter of taste, but a decision based on substances, risk, standards, ventilation concept, and suitability for everyday use. If you evaluate these points in a structured manner, you will quickly find the right system—and create sustainably clean process air for humans, the environment, and machines.

Learn how fires start, why spark arrestors are effective, and what is important when it comes to selection, installation position, and maintenance.", "fulltext": "Preventing fires in filter systems: Using spark extinguishers correctly Glowing particles are part of everyday life in metalworking—during welding, grinding, or thermal cutting. What many people underestimate is that these particles can be carried away by the air flow and end up in hose systems, pipelines, and filter systems. In the worst case, a single ember is enough to ignite deposits or filter media. In this article, we show how fires typically start – and why a spark extinguisher can be a simple, effective preventive measure. Why filter systems can catch fire in the first place Fires in extraction systems rarely start “out of nowhere.” Usually, several factors come together: Ignition source: Sparks, glowing chips, hot particles from the process Transport route: Hose/pipe carries the particles further (often faster than expected) Combustible material: Dust deposits, filter cake, possibly oil/emulsion components or fine particle mixtures Oxygen & energy: The air flow provides both – and keeps the reaction going The drier and finer the dust, the more critical the situation can become – especially with longer hose lengths, high flow velocities, or irregular maintenance. Typical risk processes in metalworking Critical particles occur particularly frequently in these applications: Welding (welding spatter, flying sparks depending on the process/material) Grinding/deburring (glowing particles at high energy) Plasma/flame cutting (hot particles and slag components) Dry machining (dust without “cooling” liquid) If these particles travel unchecked toward the filter, the filter system may become a “final storage site” for ignition sources. Spark extinguishers: Preventive fire protection in the air stream A spark extinguisher is designed to cool or “defuse” sparks and glowing particles before they reach the filter. The principle: targeted air flow or deflection causes particles to lose temperature and energy, significantly reducing the risk of something igniting in the system. Important: a spark extinguisher is no substitute for a risk assessment, but it is often a very effective, pragmatic component of a safety concept. The key point: install as close to the source as possible In practice, the position makes all the difference. Recommendation: Install the spark extinguisher as close as possible to the point of capture. Why? Because this prevents sparks from traveling long distances in the hose system in the first place – exactly where deposits can form and fires can “migrate.” Mnemonic: The shorter the distance to the “defusing” point, the lower the fire risk in pipes and filters. Selection & installation: What matters in practice To ensure that a spark extinguisher really helps in everyday use, you should pay attention to the following points: Design to suit the air volume flow (too small = high losses/poor effect, too large = unnecessary) Choose the type of installation to suit the system or workplace (e.g., in the pipeline or as a module) Ensure accessibility for visual inspection (even if it is often low-maintenance mechanically) Check the overall concept: This includes hose lengths, bends, pre-separation, filter concept, and maintenance intervals If you frequently work with flying sparks, it is worth considering this issue not as an “accessory” but as an integral part of system planning. Additional measures that have proven effective A spark extinguisher is powerful – but it is even better if you take a holistic view of the system: 1) Pre-separation for high particle volumes If there is a lot of coarse dust or chips, pre-separation (e.g., according to the principle of gravity) can relieve the load on the filter and system – and at the same time reduce combustible material in the filter area. 2) Monitoring instead of surprises For processes involving flying sparks, filter/system monitoring can be useful for detecting mechanical or thermal damage at an early stage and reacting in good time. 3) Maintenance Avoid deposits in pipes (cleaning intervals) Empty containers regularly Change filters according to schedule (and handle contaminated dust safely) Minimize ignition sources in the workplace (spark direction, shielding, process parameters) Mini checklist for HSE & maintenance Quick check in the workplace: Are there visible flying sparks or glowing particles in the process? How long is the distance to the system (hose/pipe)? Where do dust deposits accumulate (bends, reducers, horizontal sections)? Is pre-separation or spark extinguishing provided for? Are maintenance, emptying, and filter changes documented and adhered to? If you hesitate on 2–3 points: This is usually the moment when it is worth taking a look at the safety concept. Conclusion: Safety is not a coincidence – it's a system Fires in filter systems are not inevitable. If you understand the chain of events that leads to a fire, you can interrupt it: defuse ignition sources, shorten transport routes, reduce deposits, and monitor the system cleanly. A spark extinguisher is one of the most effective measures for this – especially if it is located close to the emission source and fits into the overall concept.

A HEPA particle filter is the heart of many extraction systems—especially where fine particles must be captured safely. But when is the right time to change it? In practice, there are two clear signals: decreasing suction power and a filter change indicator on the display. As soon as one of these occurs, the following applies: Change the filter – correctly, safely, and with documentation. How can I tell when the HEPA filter needs to be changed? During operation, the filter load increases – often faster than you might think, depending on the application. Typical signs are: The suction power noticeably decreases The system display indicates that the filter needs to be changed These indications are deliberately practical: if the system signals that the filter needs to be changed, the change should be carried out promptly. This ensures that the system remains efficient and workplace protection remains reliable. Why does the replacement interval vary? There is no universal time frame, as the replacement interval depends heavily on usage. Among other things, the following factors are decisive: Material and process (e.g., dry dust, abrasive particles, mixing processes) Particle load (quantity and fineness of the particles) Duration of use (shift operation, running time per day, peak loads) In short: The more intensive the application, the more frequently the filter must be checked and replaced. Safe filter replacement: How to do it right When it's time to replace the filter, safety comes first – especially when working with hazardous substances. 1) Only with personal protective equipment (PPE) When working with hazardous substances, the filter may only be replaced with suitable PPE. This reduces the risk of coming into contact with contaminated filter material during removal. 2) Check, replace, and safely dispose of filters The procedure is clear: Check the condition of the filter Replace the filter properly Dispose of the filter safely and in accordance with the specifications Safe disposal is essential, especially for contaminated filters – for health protection, the environment, and compliance. 3) Document filter replacement An often underestimated step that is very useful in everyday life: documentation. It ensures: Traceable maintenance (e.g., for audits/EHS) Plannable service intervals Consistently stable system performance The result: The system is running optimally again – and you are working with reliable extraction performance. Conclusion: The right time is when the system indicates it – or when performance declines When the extraction performance declines or the display indicates that the filter needs to be changed, the time has come. Then it's time to change it – safely, correctly, and with documentation. This keeps your TBH extraction system performing at its best and workplace safety at a high level.

Replacement interval: usage is decisive How often the activated carbon filter should be replaced depends heavily on the application – for example, on: Type and concentration of pollutants Operating times and utilization Environmental influences (temperature, humidity) Pre-filter condition (dust exposure affects service life) TBH recommends at least one change per year – in intensive applications, a shorter cycle may be advisable. Important: Activated carbon filter is not shown on the display In many systems, the activated carbon filter is not monitored separately on the display. This means that the replacement must be actively included in the maintenance schedule and organized accordingly – e.g., via inspection intervals, maintenance lists, or internal QM specifications. Safety first: Only replace with PPE when handling hazardous substances If your system separates hazardous substances, the following applies: Only change filters with personal protective equipment (PPE) and in accordance with internal safety specifications (e.g., operating instructions, risk assessment). We recommend following this procedure: Check – replace – pack securely – dispose of properly. Disposal & documentation: Please remove cleanly Activated carbon filters may be contaminated depending on the application and must be treated accordingly. Dispose of filters properly via your environmental officer or the responsible department in your company – including documentation (e.g., disposal certificate, internal log, maintenance log). This ensures safety, transparency, and compliance. Conclusion A fresh activated carbon filter ensures reliable protection of air quality, reduces odors, and helps to keep measurement results stable.

At the same time, legal requirements for the protection of employees and compliance with national regulations are increasing. This is exactly where we come in. At Global Industrie, we will be showcasing several of our filter and extraction systems live at our booth. Visitors will gain direct insight into how our systems work and can discuss specific applications with us. The focus will be on initial discussions about real processes, individual questions, and how legal requirements in France can be met in a technically sensible manner. You can find us at booth 6T114. We look forward to meeting you in person and to discussions that go beyond theoretical solutions." }, { "title": "What are fine dust filters?", "url": "https://www.tbh.eu/en/blog/what-are-fine-dust-filters/", "type": "blog", "last_modified": "2026-02-13", "summary": "Fine dust is invisible—and can penetrate deep into the respiratory tract. Read here to find out how fine dust filters and HEPA H13/H14 remove ultrafine particles, aerosols, and toxic dust from the air.", "fulltext": "Fine dust is tiny, often invisible—and can penetrate deep into the respiratory tract. Fine dust filters (e.g., HEPA H13/H14) reliably remove ultrafine particles, toxic dusts, and aerosols from the air. This protects employees, processes, and the environment. Fine dust: small, invisible, risky Many industrial processes produce particles that are barely visible – but can be inhaled. The smaller the particles, the deeper they can penetrate into the respiratory tract. This is exactly where fine dust filters come into play: they remove suspended matter (particles and aerosols) from the air, thereby making a decisive contribution to cleaner process air and better occupational safety. What exactly are fine dust filters? Fine dust filters (also known as suspended particle filters) are highly efficient air filters that separate very small particles from the air. HEPA filters (High Efficiency Particulate Air) are particularly well known. They are used wherever maximum filtration is required – e.g., for industrial fine dust, toxic dusts, or aerosols. Classification: ISO 16890, EN 1822 – and what that means Standards and classes exist to clarify how good a filter is. In practice, you will mainly encounter: 1) ISO 16890 (particle sizes in ambient air) ISO Coarse: Retention capacity against ISO A2 dust ISO PM10: Particles ≤ 10 µm ISO PM2.5: Particles ≤ 2.5 µm ISO PM1: Particles ≤ 1 µm 2) EN 1822-1:2009 (Particulate filters – EPA/HEPA/ULPA) This standard divides high-performance filters into: EPA (E10–E12) HEPA (H13–H14) ULPA (U15–U17) HEPA H13/H14 in particular stand for very high separation efficiency and are therefore frequently used in demanding applications. How do HEPA filters achieve this high level of separation? High-quality fine dust filters consist of a dense fiber network (e.g., made of cellulose and synthetic materials) – often in many layers. Typical characteristics that are often cited for HEPA applications: > 1000 layers of filter medium Separation efficiency > 99.9% for particles in the range 0.1–0.3 µm Only a very small residual amount passes through the filter Important: Performance depends not only on the filter medium, but also on the overall system (air flow, tightness, maintenance, replacement intervals). The most common mistake: changing filters too late As powerful as fine dust filters are, they are wear parts. When filters are saturated, air performance decreases and hygiene can suffer. In certain environments, changing filters too late can also increase the risk of undesirable microbiological contamination developing in contaminated filters. Modern extraction systems therefore often work with filter monitoring/warning indicators that signal in good time when the filter needs to be changed (e.g., via filter saturation indicators and early warning stages). Fine dust filters are part of a protection concept Especially in dust-intensive work areas, filters are only one component. The following combination has proven effective: Dust prevention   (where possible) Direct capture at the source (extraction at emission points) Efficient filtering (appropriate filter classes depending on the risk) Ventilation concept (sensible planning of supply/exhaust air) Personal protective equipment (as a supplement) This creates effective protection – for employees, processes, and the environment. Short & sweet (for those in a hurry) Fine dust is often invisible, but can penetrate deep into the lungs. HEPA H13/H14 filters ultra-fine particles particularly efficiently. Standards such as ISO 16890 and EN 1822 help with classification. Change regularly! Otherwise, performance will decline and the risk will increase. Conclusion: Clean air is not a “nice-to-have.” Fine dust filters are a key lever for better air quality in industry – and thus for health, process safety, and sustainable operation.

Read on to find out what this means for businesses and what rules apply in the workplace.", "fulltext": "Clean air is a fundamental prerequisite for health, well-being, and sustainable economic activity. At the same time, however, the question arises how it is determined which levels of air pollutants are still acceptable – and from which point onward health is at risk. Especially against the backdrop of increasing industrial processes and urban pollution, clearly defined limit values play a crucial role. In Europe, these regulations form the framework for uniform public health protection. European Regulations on Air Quality The EU Air Quality Directive 2024/2881 With Directive (EU) 2024/2881, the European Union has established binding limit values for air quality. This directive was adopted by the European Parliament on 23 October 2024 and replaces earlier regulations with updated and more stringent standards. In doing so, the EU creates a uniform basis for limiting and harmonising air pollutant exposure across Europe. Objectives of the Directive The directive pursues several key objectives that are closely interconnected: Ensuring sustainable and environmentally sound development in Europe Reducing concentrations of pollutants in the air we breathe Protecting the population from health damage caused by toxic substances Thus, the focus is not only on environmental protection but, above all, on long-term preventive health care. Defined Limit Values for Air Pollutants To achieve these objectives, the directive defines binding limit values for various air pollutants. These include, among others: Sulphur dioxide (SO₂) Nitrogen dioxide (NO₂) and nitrogen oxides (NOₓ) Particulate matter (PM2.5 and PM10) Lead (Pb) Particular attention is paid to anthropogenic particulate matter, i.e. particles generated by human activities. Compared to natural dust, it is considered significantly more harmful to health and must therefore not exceed defined limit values. Protection of Particularly Vulnerable Groups In addition, the directive takes into account particularly vulnerable groups. For children, older people, or hospital patients, additional and more stringent requirements may be defined in order to protect health as effectively as possible. Air Quality in the Workplace: National Regulations Supplementary Regulations in Germany In addition to European requirements, there are binding national regulations in Germany that specifically govern the protection of employees in the workplace. These national provisions specify concrete requirements for occupational environments and are mandatory for employers. These include, among others: Workplaces Ordinance (ArbStättV): Protection of employees against health hazards ASR A3.6 “Ventilation”: Definition of requirements for ventilation and air quality in workspaces Hazardous Substances Ordinance (GefStoffV) in conjunction with TRGS 900: Binding occupational exposure limits for hazardous substances Organisational and technical measures: Regular ventilation, use of ventilation systems and air filters, and the implementation of risk assessments This ensures that air quality is not only monitored and improved in public spaces, but also directly at the workplace. Overview of Key Regulations Regulation / Directive Content / Objective Source Directive (EU) 2024/2881 Air quality limit values in Europe (SO₂, NO₂, NOₓ, PM2.5, PM10, lead) EUR-Lex ArbStättV Basic protection of employees Federal Ministry of Labour and Social Affairs ASR A3.6 “Ventilation” Requirements for ventilation and air quality in workspaces BAuA GefStoffV / TRGS 900 Occupational exposure limits for hazardous substances BAuA VDI 2262 Part 1 Air quality in the workplace, measures to reduce exposure VDI Guideline Conclusion: Air Quality Is Clearly Regulated In summary, air quality is strictly regulated and monitored at both European and national levels. While the EU directive defines the overarching framework, national occupational safety regulations ensure that employees are effectively protected from harmful exposure in the workplace. For companies, this means: Proactive measures such as the use of extraction and filtration systems are not only sensible, but in many cases legally required. In this way, companies protect their employees and the environment while simultaneously complying with applicable regulations." }, { "title": "Finding an extraction system: How to choose the right solution for your process", "url": "https://www.tbh.eu/en/blog/finding-an-extraction-system-how-to-choose-the-right-solution-for-your-process/", "type": "blog", "last_modified": "2026-02-05", "summary": "Choosing the right filter system is crucial for clean air, healthy workplaces, and long-lasting machines. Find out which factors really matter when making a purchase.", "fulltext": "Clean air in the workplace is not a luxury, but a prerequisite for health, environmental protection, and plant safety. Anyone looking for an extraction system for air filtration is faced with the key question: Which solution is right for my manufacturing process? The choice is vast—but not every system is suitable for every application. This guide outlines the most important criteria. 1) Process analysis: What emissions are produced? The basis for every decision is the production process. Different applications generate different emissions: Coarse dust (e.g., grinding) Fine dust (e.g., laser cutting, welding) Smoke/fumes (e.g., chemical processes) The more precisely the type and quantity of particles are known, the more accurately the extraction system that is technically and economically suitable can be found. 2) Selecting the right filter technology The filter stage is the heart of every system. The decisive factor is adaptation to particle size and quantity: Coarse dust → Pre-filter or cartridge filter with high capacity for infrequent replacement and low operating costs. Fine dust → Fine or HEPA filters (e.g., H13/H14) for reliable separation of even the smallest particles. The right combination reduces health risks and prevents downtime due to contaminated machines. 3) Correctly dimension air volume flow & motor power The air volume flow must be appropriate for the process and collection (hoods, nozzles, hoses), otherwise particles will not be collected effectively. The motor power depends on the amount of dust and the operating time: High load/long-term operation → powerful drive Smaller applications → compact, energy-efficient solution 4) Ergonomics & practicality In addition to separation performance, everyday use is also important: Space requirements: compact design for confined production areas Mobility: casters/modular design for flexible use Noise: low noise level increases acceptance Accessories: easy-to-handle hoses/tubes, suitable collection elements Conclusion The right extraction solution is the result of a balance between process requirements, filter technology, and practicality. Taking these factors into account ensures clean air, safe working conditions, and a longer machine service life. Tip: Expert advice helps to avoid incorrect dimensioning and follow-up costs – this is the most efficient way to find the right extraction system." }, { "title": "Clean room", "url": "https://www.tbh.eu/en/extraction-solution/particulate-matter/clean-room/", "type": "page", "last_modified": "2026-01-08", "summary": "Clean room Cleanrooms are microbiologically controlled.

The focus is on dust sizes and health risks: particle size determines dispersion, filterability, and health hazards. The smaller the particles, the deeper they penetrate the respiratory tract and the more difficult they are to remove. In industry, medicine, and everyday life, particles range from coarse dust to ultrafine aerosols—each class poses its own risks. Metal processing and medical laser procedures in particular produce very different size fractions, which should be specifically identified and evaluated. The following overview shows typical size ranges, examples, and health relevance.   Particle size range Typical particle examples Comparison from everyday life Notes on frequency & health 10–27 μm Larger lumpy particles (rare, outliers) Fine grain of sand (approx. 25 μm) Rare, especially in extremely high-energy laser operation 1–10 μm Coarse fine dust particles (few larger splashes) Human hair: 60–100 μm (1–10 μm = 1/10 to 1/6 as thick as a hair) Can settle, especially in the upper respiratory tract 0,3–1 μm Main mass of smoke particles (material cut) Red blood cell: ~7–8 μm; pollen: 10–100 μm Visible smoke, penetrates deep into the lungs 0,1–0,3 μm Largest proportion (fine/ultrafine) Bacteria: ~1 μm; these particles are 1/10 to 1/3 as large Penetrates into the alveoli, high health risk 10–100 nm (0,01–0,1 μm) Ultrafine particles (most numerous) Coronavirus: ~0.1 μm Extremely respirable, difficult to filter with masks Important comparisons for scale Human hair: 60–80 μm thick. Even the largest particles in laser smoke are usually only 1/10 to 1/1000 as wide. Pollen grain: 5–200 μm. The largest laser smoke particles just reach the lower end of this size range. Red blood cell: ~7–8 μm. Most laser smoke particles are significantly smaller. Typical bacteria: ~1 μm. The fine and ultrafine components of laser smoke are often even smaller. Viruses (e.g., coronavirus): ~0.1 μm. Many ultrafine smoke particles are comparably small. Coarse dust: greater than 10 µm Fine dust: less than 10 µm Ultrafine particles: less than 0.1 µm Particle distribution in laser smoke Most common: Fine and ultrafine particles (0.1–1 μm) dominate in terms of number and mass, depending on the process. Smallest particles: Reach sizes around 10 nm (0.01 μm) – far below the filtration limit of normal masks. Largest particles: Approx. 27 μm, but very rare; more common in uncontrolled processes.

Current research shows that ultrafine particles increase the risk of cancer and promote inflammation. For metalworking, this means robust occupational safety concepts with modular filter and extraction systems—so that particulate matter does not become an operational risk.", "fulltext": "Health and occupational safety risks in metalworking Particulate matter is not only an invisible environmental problem that poses a serious health risk—it can also be carcinogenic. Scientific studies increasingly show that ultrafine particles (PM2.5) that penetrate deep into the lungs can have carcinogenic effects. Here is an overview of what studies and research findings show. Evidence of carcinogenic effects Animal experiments have clearly confirmed the carcinogenic potential of particulate matter: a study by the Federal Institute for Occupational Safety and Health (BAuA) showed that rats developed lung tumors significantly more often than expected even at realistic levels of particulate matter exposure. Researchers assume that the mechanisms are similar in humans. Two possible mechanisms of action are being discussed: The fine dust particles can directly damage cells and have a carcinogenic effect (direct genotoxicity). Alternatively, phagocytes of the immune system produce carcinogenic substances after absorbing the particles, which represents indirect, mediary genotoxicity. Epidemiological evidence from human studies Long-term studies on humans support these findings. Analyses from large cohorts show that increased fine dust exposure significantly increases the risk of lung cancer. For example, according to a study in Hong Kong, the risk of cancer mortality increased by up to 22 percent with each increase in fine dust concentration. The studies also point to links with other types of cancer, such as tumors in the digestive tract or breast cancer. Particulate matter as a tumor promoter Particulate matter triggers inflammatory reactions in the body that can promote tumor development. This has also been confirmed by studies with genetically modified mice, in which particulate matter promoted the development of lung tumors without directly altering the genetic material. Particulate matter thus acts as a “booster” for cancer growth. Significance for metal processing and occupational safety Exposure to particulate matter in the workplace is a serious cancer risk for employees.

Particulate matter is an invisible risk in metalworking. It poses a daily threat to the health of many skilled workers. This presents companies with considerable challenges. Anyone who underestimates the danger risks damage to people and machines. A customizable filter and extraction solution specifically reduces the risk. Invisible danger: particulate matter in everyday working life Grinding, cutting, or welding produces very fine particles. These particles originate from metal and other materials. They disperse almost weightlessly in the air. Particulate matter remains invisible and is therefore particularly treacherous. It penetrates deep into the respiratory tract and irritates the tissue. Ultra-fine particles can pass through the alveoli. They enter the bloodstream and affect the entire body. Health consequences of fine dust exposure Even small amounts can have serious consequences. Typical symptoms include coughing, shortness of breath, and inflammatory reactions. In the long term, there is a risk of chronic bronchitis, asthma, and COPD. Metals also enter the body with the dust. These include nickel, lead, and cadmium. These substances damage the kidneys and cardiovascular system. They increase the risk of cancer. Studies show systemic inflammation caused by ultrafine dust. Neurodegenerative risks such as Parkinson's and Alzheimer's also increase. What companies should do Legislation sets strict limits for particulate matter. In practice, these limits are often exceeded. Effective filter and extraction systems provide reliable protection for employees. They prevent disruptions and breakdowns in processes and machines. Modular systems can be adapted to fit any workplace perfectly. “Made in Germany” stands for quality and safety. Emotional security and responsibility Responsible employers ensure healthy air in the workplace. This creates trust and retains skilled workers.

Put it into an envelope and attach it clearly visible on the system, that our employees can see it immediately.) Shipping instructions for returned systems It is very important for us at TBH to protect our customers from hazardous pollutants by using our extraction systems. The health and safety of our employees is equally important to us. Therefore, we ask for your understanding to consider the following instructions for returned systems: Used filters or filters that are contaminated with harmful substances must be removed from the systems before sending them back! Generally, the filters are not required for inspecting and repairing a system and are a potential health risk. Our employees could inhale released pollutants while unpacking and subsequently handling the systems after they arrived at our site. We would like to avoid that. In general, please do not send us any used or contaminated filters. They are hazardous waste. You must dispose of them in accordance with local regulations, at your local disposal company.  ATTENTION: If we receive a shipment with used filters, our staff is instructed to dispose of them immediately at your expense. In this case we will be charging you a disposal fee. The amount depends on various factors such as the type and size of the filter(s). If the systems or single units show external soiling, we ask you to clean them at least roughly if possible. Especially if the deposited particles could be hazardous pollutants. Please ensure proper packaging to avoid transport damage. Systems and single units should be shipped upright and not lying down, must be secured, and well-wrapped on a pallet and shipped by a forwarding agent! If you want to return unused, larger replacement filters, e. g. from a TFS or LN600 series, or heavy activated carbon filters, you must secure them on a pallet and ship them by a forwarding agent as well. Ideally you can use the same pallet on / packaging in which you got the filters.  " }, { "title": "Service", "url": "https://www.tbh.eu/en/service/", "type": "page", "last_modified": "2022-10-19", "summary": "Service We provide many different services such as taking time talking to you.
