Key Fume Capture Strategies & Equipment

Source capture is essential, utilizing movable extraction arms, fume hoods, or integrated MIG gun extraction to pull contaminants away from the operator's breathing zone.

TC

Laser and Thermal Cut Smoke Capture

Laser processing generates a complex mixture of fumes

Robotic laser systems require fully enclosed, ventilated, and fire-resistant filtration to handle high-volume fumes and hazardous metal  Laser cutting and welding produce a large number of gas and particulate contaminants that are difficult to manage. Having ample filtration and a well-designed fan system is crucial. Clogged filters can cause significant downtime, so selecting the right equipment is essential. Providing clean, safe extraction of these fumes is a safety and health concern. Applying proper source capture techniques and airflow calculations ensures a properly functioning extraction system with no downtime.

Types of Capture for Heavy Smoke

  • Source Capture Systems: Capture smoke directly at the source using extraction arms or hoods, preventing it from reaching the operator's breathing zone.
  • Integrated Fume Extraction MIG Guns: These systems are highly effective for manual welding, as they pull fumes directly from the torch, preventing dispersion.
  • Cartridge Dust Collectors: Recommended for laser applications due to their efficiency in handling submicron particulate; these can be portable or centralized.
  • Enclosed Systems (Robotic): Robotic laser welding should occur inside a sealed, ventilated enclosure to capture the high-volume fumes generated, which also keeps the optics free of debris

    Key aspects of welding and thermal cutting filtration

    To mitigate these risks, filtration systems are used to capture and remove these contaminants from the air.

    Hex-Chrome

    Why is filtration important?

    Worker Health:

    Welding and thermal cutting processes release various metal fumes and gases, some of which are toxic and can cause respiratory problems, skin irritation, and long-term health issues

    Environmental Compliance:

    Regulations often require businesses to control emissions of dust and fumes to protect the environment.

    Equipment Protection:

    Uncontrolled fumes can accumulate on machinery, electrical components, and other equipment, leading to damage and downtime.

    Productivity:

    A healthy and safe working environment can boost productivity by reducing worker stress and absenteeism.

    How do filtration systems work?

    Extraction:

    Welding fume extractors use fans or suction to draw in the air containing fumes and dust.

    Filtration:

    The captured air then passes through a filter, which removes the contaminants.

    Recycling or Exhaust:

    The clean air is either recycled back into the workplace or expelled outside, depending on the specific filtration system.

    Types of Filtration Systems:

    Dust and Fume Collection Systems:

    These systems are designed to capture and filter welding fumes and dust from processing areas or entire facilities.

    HEPA Filtered Welding Fume Extractors with AUTO-Pulse

    HEPA Filters:

    These filters are highly efficient in capturing fine particles, including those found in welding fumes.

    Active Carbon Filters:

    Carbon Filtration
    Dust Collector Exhaust Plenum - Contains 50 lbs. of 4mm activated carbon pellets

    These filters are used to remove paint mists and other gaseous contaminants from welding fumes. 

    A custom blend of activated carbon pellets and potassium permanganate pellets is used to eliminate odors. Having the right amount of “dwell time” for the VOC within the carbon is essential to the success of the unit.

    Different contaminants call for different kinds of filtration

    Horizontal Media Collector
    Horizontal Media Collector

    Different contaminants call for different kinds of filtration. HEPA won't eliminate VOC and Carbon won't filter particulate all that well. 

    Sometimes a combination of filtration is called for. What order they go in is crucial also.

    NEMA Ratings for Industrial Vacuums Explained

    These ratings help ensure that the chosen enclosure is suitable for the specific application and environment.

    NEMA

    NEMA Explained

    NEMA ratings are a standard system developed by the National Electrical Manufacturers Association (NEMA) to classify electrical enclosures based on their ability to protect internal components and personnel from external environmental conditions and hazards. 

    Key Aspects of NEMA Ratings and Protection Levels:

    NEMA ratings indicate the level of protection an enclosure provides against various environmental factors like dust, water, and corrosion.

    Application Specific:

    The ratings help engineers and manufacturers select the appropriate enclosure for their specific needs, ensuring that the enclosure can withstand the intended operating conditions.

    NEMA ratings also consider protection against personnel access to hazardous parts within the enclosure. 

    Common NEMA Ratings:

    NEMA 1 (General Purpose): 

    Designed for indoor use and provides protection against light dust and indirect splashing, but it is not dust-tight. 

    NEMA 3R (Weatherproof): 

    Primarily for outdoor use, offering protection against rain, ice, and snow. 

    NEMA 4 (Watertight): 

    Designed for both indoor and outdoor use, offering protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water. 

    NEMA 4X (Corrosion-Resistant): 

    Similar to NEMA 4, but with additional corrosion resistance for use in harsh environments. 

    NEMA 12 (Industrial): 

    Suitable for indoor use and provides protection against falling dirt, circulating dust, and lint. 

    NEMA 4X (Corrosion-Resistant): 

    Similar to NEMA 4 but with added corrosion resistance for use in harsh environments. 

    Type 5 Enclosures constructed for indoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and settling airborne dust, lint, fibers, and flyings); and to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (dripping and light splashing).

    Type 6 Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (hose directed water and the entry of water during occasional temporary submersion at a limited depth); and that will be undamaged by the external formation of ice on the enclosure.

    Type 6P Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (hose directed water and the entry of water during prolonged submersion at a limited depth); that provides an additional level of protection against corrosion and that will be undamaged by the external formation of ice on the enclosure.

    A dusty floor comes with health risks

    Respiratory Irritation:

    Dust particles can irritate the nose, throat, and lungs, causing symptoms such as coughing, sneezing, and difficulty breathing. 

    Allergies:

    Some individuals may develop allergic reactions to specific dust components, resulting in symptoms like skin rashes, nasal congestion, and breathing difficulties. 

    Asthma:

    For those with asthma, dust exposure can exacerbate symptoms, leading to increased wheezing, chest tightness, and difficulty breathing.

    Chronic Lung Diseases:

    Prolonged exposure to dust, especially certain types like silica dust, may lead to chronic lung diseases such as silicosis, which can impair lung function and increase the risk of tuberculosis and lung cancer. 

    Known carcinogens are generated from various industrial processes

    Cement dust contains silica, stainless steel dust contains hexavalent chromium. Both are known carcinogens. Having a layer of dust on a floor is a hazard every time that dust is kicked by human traffic, equipment, HVAC, and a variety of means.

    OSHA Approved HEPA Vacuums for Silica and Hex-Chrome

    In 2017, OSHA updated its silica dust regulations, reducing the permissible exposure limit (PEL) to 50 micrograms per cubic meter of air (µg/m3) averaged over an 8-hour workday. This standard also established an action level (AL) of 25 µg/m3. The updated rules, first enforced in September 2017 for the construction industry, require employers to ensure that worker exposure to silica dust remains below the PEL. 

    Permissible Exposure Limit (PEL):

    The PEL is now set at 50 µg/m3, meaning the maximum amount of silica dust an employee can be exposed to over an 8-hour period is 50 micrograms per cubic meter of air. 

    Control Measures:

    OSHA requires employers to use engineering controls, work practice controls, and respirators to keep worker exposure to silica dust at or below the PEL.  One of these methods of controlling the dust is use of HEPA Filtration.

    "Our vacuum is also a dust collector"

    This is a common claim from vacuum companies that lack a dust collector to offer you for your pouring or batching process. 

    The reason a vacuum won't function properly as a “dust collector”.
    A vacuum won't function properly as a “dust collector” because the area has a direct relationship to air volume. Vacuums feature a small diameter inlet to achieve the required capture velocity when pulling dirt and dust off a flat surface. Expanding the inlet to allow for greater volumetric flow directly reduces static lift, diminishing vacuuming power.

    A wider inlet and a different fan design are necessary to effectively capture airborne dust. Dust collectors lack the high static lift that vacuums possess, as they would only end up sucking up the product when all you need them to do is capture the "lighter-than-air" nuisance dust.

    How to pick the correct Downdraft or Wet Collector

    Dust Hazard Analysis (DHA) is the first step

    A Dust Hazard Analysis (DHA) is a systematic process defined by NFPA 660 to identify and evaluate potential fire, deflagration, and explosion hazards associated with combustible dust and particulate solids in a facility, offering recommendations to manage those risks. 

    Once your dust is analyzed it is best to follow the direction of your AHJ or EHS, and the recommendations given by the testing lab. 

    If you are sanding conductive metal, a Wet Dust Collector is essential.

    If you are sanding conductive metal, a Wet Dust Collector is essential. OSHA prohibits the use of HEPA filters in Wet Collectors unless they are equipped with a heat sensor that shuts them down. This is because aluminum fines can remain in the HEPA filter after drying, which poses a fire hazard and has led to fires.

    A wet dust collector filters to about 10 micron

    Other than conductive dusts, Wet Collection is quite inefficient and can lead to a lot of dust-bypass.  Having visited lots of plants where wet dust collection is used, the first thing you will notice is dust all over the floor.   This is because most wet dust collectors don't have proper HEPA filtration as water and paper are not a good combo, for a lot of reasons.

    Applications where Wet Dust Collection is not suitable

    If you are sanding plastics, or graphite, anything with Silica, then you need proper HEPA Filtration that captures particulate down to .3 micron at 99.97% efficient. Water as your main filter will only allow the dust to completely bypass the unit.

    Step 3: Determine the required ACH

    Air changes per hour (ACH) indicates how many times the air in a room is replaced each hour. Recommended ACH values vary by room type: Bedrooms (5–6), Living Rooms (6–8), Kitchens (7–8), Bathrooms (7–8), and Laundry Rooms (8–9).

    Step 4: Calculate the CFM

    Use the room's volume and the chosen ACH in the CFM formula.

    Extraction Solutions for Dust Containing Hex-Chrome

    What is Hexavalent chromium?

    Hexavalent chromium (Cr(VI)), a toxic form of chromium, is a known human carcinogen, particularly when inhaled, leading to increased risk of lung cancer and other cancers.

    OSHA Regulations:

    The Occupational Safety and Health Administration (OSHA) recognizes hexavalent chromium as a carcinogen and has specific regulations to limit worker exposure. 

    Welding can produce Hex-Chrome and other toxic gasses

    During welding, the high temperatures oxidize chromium in the metal to its hexavalent state (Cr(VI)), which is a toxic form of chromium. 

    Other Toxic Fumes and Gases:

    Besides hexavalent chromium, welding fumes can contain other harmful substances like iron oxide, manganese, nickel, and other metal oxides. 

    Source Capture of Welding Fumes

    The preferred method for capturing hex chrome dust is a Dust Collector or a Vacuum, with a High-Efficiency Particulate Air (HEPA) filter, which captures 99.97% of particles 0.3 microns in size.

    “The Great Mill Disaster” of 1878

    Organic dust explosions are not new. Following 'The Great Mill Disaster' of 1878, a catastrophic grain mill explosion at The Washburn Mill in Minneapolis, Minnesota, significant measures were taken to prevent similar incidents. 

    Flour dust was the cause of the explosion

    Over the past 35 years, there have been more than 500 accidents, 675 injuries, and 180 deaths, all caused by one thing: flour dust, which is more explosive than gunpowder and 35 times more combustible than coal dust.

    The effects of the explosion?

    The explosion that destroyed Washburn A Mill, the world’s largest grain mill, along with several nearby mills, cut the city’s milling capacity by nearly half and claimed the lives of eighteen people. This incident, attributed to a buildup of grain dust, sparked extensive discussions and initiatives aimed at improving industrial safety and preventing the accumulation of combustible dust. 

    NFPA published it's first standard on combustible dust in 1923

    NFPA published it's first standard on combustible dust in 1923. So this isn't a new problem. Companies have been reluctant to do anything due to perceived high costs. In almost every case it is a cost saving measure to address the hazard. We are happy to help you with the first steps. 

    Wet Dust Collection of Explosive Metal Powders

    A wet dust collector, also known as a wet scrubber, uses water or another liquid to trap and remove dust particles from air streams, often preferred for applications involving potentially explosive or flammable materials. 

    Water is used to neutralize aluminum dust, where as neutralizing oil is used for titanium dust as water can be an accelerant in titanium fires. 

    What are some examples of explosive powders?

    • food (e.g., candy, sugar, spice, starch, flour, feed)
    • grain
    • tobacco
    • plastics, wood paper, pulp
    • rubber, pesticides
    • pharmaceuticals
    • dyes
    • coal
    • metals (e.g., aluminum, chromium, iron, magnesium, and zinc).

    Understanding OSHA regulations on combustible dust

    Currently, there are no OSHA mandates on Combustible Dusts; there are Standards that need to be followed. Even though NFPA 660 isn't a law, you can still be held accountable for safety violations. 

    What is a Dust Hazard Analysis (DHA)?

    A Dust Hazard Analysis (DHA), as outlined by NFPA 660, is a systematic process for identifying and evaluating fire, flash fire, and explosion hazards associated with combustible dust and particulate solids in a facility, ultimately providing recommendations to manage these risks. 

    The new NFPA 660 will incorporate the following standards

    • NFPA 61
    • NFPA 484

    What is an Explosion Proof Vacuum?

    An Explosion-Proof Vacuum System is a vacuum system capable of preventing the ignition of a specified gas or vapor and operates at such an external temperature that a surrounding flammable atmosphere will not be ignited.  A Nationally Recognized Testing Lab (NRTL) must certify that a vacuum system is explosion-proof.

    What is an Intrinsically Safe Vacuum Cleaner?

    An Intrinsically Safe Vacuum is one that operates with no moving parts and no electrical parts. The power is supplied by compressed air that is fed into a tapered restriction also called a  “venturi”.  Intrinsically safe vacuums are made from non-sparking metals like stainless steel and aluminum. Mild steel is not suitable as it can create a spark when a nut or a screw is vacuumed. It will create a spark when it hits the wall of the vacuum dirt-bin.

    Class II, Group E Aluminum and Titanium Dust Vacuuming

    NFPA 660  Chapter 8 Combustible Metals. Portable Vacuum Cleaners. The use of portable vacuum cleaners shall comply with 22.8.4.2.2. (B)*Due to the inherent hazards associated with portable electric vacuum cleaning systems, the equipment used for cleaning shall be identified for use in Class II, Group E atmosphere. 

    Choosing the right vacuum or dust collector

    We take several factors into consideration. From the bulk density of the product being vacuumed,  the Kst and Pmax values, to the electrical requirements under NEC 70. Safety as well as productivity are taken equally into consideration. 

    Do I need an Explosion Proof Vacuum?

    If your area is HAZLOC, then yes. If you area is ORDLOC and the Kst value of the powder is low, then an NFPA 660 Compliant Vacuum is required. 

    Vacuums made from non-sparking materials, motors located in the clean air stream, and critical filtration are built this way to ensure a safe and productive workplace.

    What Is Static Electricity?

    Static electricity is a buildup of electric charges on objects. Charges build up when negative electrons are transferred from one object to another. The object that gives up electrons becomes positively charged, and the object that accepts the electrons becomes negatively charged. This can happen in several ways.

    Static Conductive meaning:

    Conductivity is a material's ability to allow electrical charges (electrons) to move through it. 

    Static Dissipative meaning:

    "Static dissipative" refers to materials or objects that allow static electricity to flow slowly and in a controlled manner, preventing sudden, potentially damaging electrostatic discharges (ESD). 

    High Concentration of Conductive Resin in Hose Material

    A vacuum hose whose only means of eliminating static is a copper ground wire running through the helix is considered static­ dissipating. Lower concentrations of conductive resin are also regarded as static dissipating. 

    A Conductive Hose has higher levels of conductive resin impregnated within the hose construction. 

    The conductive hose is better for fighting static than the hose with a ground wire, contrary to what many people believe. A hose's static conductivity is measured in units of "sheet resistance" or ohms squared. You should look at the surface resistivity levels, not whether it has a ground wire.

    • Conductive: when complete dissipation of static charges is required
    • Static dissipative: when a controlled discharge is needed

    The NFPA compliance, the bulk density of the material you are vacuuming, and other factors are all considered.

    Solutions for HAZLOC

    HAZLOC Areas Require Proper 3rd Party Certified Equipment. No Exceptions.

    “Our company has done a DHA, and the dust has a Kst 300. Our area is a designated Hazardous Location. (HAZLOC). What are our options?”

    You have only one option here, and that is to use an appropriately certified vacuum or dust collector for the area. 

    Solutions for ORDLOC

    Our Company Has Done a DHA, and the Dust Has a KST of 98

    “Our company has done a DHA, and the dust has a Kst of 98. Our area is an Ordinary Location. (ORDLOC).”

    If the area is HAZLOC, then by all means, you can only use the appropriate vacuum with the correct markings and 3rd Party Certification. But if the area is ORDLOC and the dust is low Kst, then overspending on the wrong vacuum works against your needs. The fully XP vacuum can sometimes be less ergonomic and end up sitting in a closet. Purchasing a vacuum to check a box is the most common cause for this.

    Finding the Correct Vacuum That is Compliant and Productive

    You can often tell if an area is ORDLOC if you can bring in a cell phone or if ordinary light switches are present. The misconception is that getting a fully explosion-proof vacuum for low Kst dust in ORDLOC is a good return on your money. Very often, it is the worst thing you can do. A fully explosion-proof vacuum is for an NFPA HAZLOC area with airborne flammable vapors. But if you are vacuuming wood dust in a warehouse or a production area, this certification doesn't provide anything in return. In this scenario, purchasing full XP is a mere CYA exercise. A 120V NFPA 660 Safe Vacuum can give around 300 cfm from a 120V circuit, and it checks your safety and compliance boxes. The full explosion-proof 120V model costs double and only has ⅓ of the vacuuming power.

    The Hazardous Dust Still Passes Through Your Breathing Zone

    Ambient-style dust collection can pose serious risks when it comes to handling titanium dust. A simple search on "titanium dust cloud in machine shops" reveals the critical nature of airborne titanium particles. These particles are highly pyrophoric, meaning they can ignite spontaneously upon contact with air, potentially leading to a powerful explosion triggered by even a minor spark or heat source, including static electricity. Therefore, stringent safety protocols are essential when dealing with titanium dust in a machine shop setting. Titanium can affect you when inhaled. Contact can irritate the skin and eyes. Inhaling Titanium can irritate the nose, throat, and lungs. Titanium powder is FLAMMABLE and SPONTANEOUSLY COMBUSTIBLE. 

    Titanium Dust - Health Hazard Information

    • Acute Health Effects The following acute (short-term) health effects may occur immediately or shortly after exposure to Titanium:
    • Contact can irritate the skin and eyes. Inhaling Titanium can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath.
    • Chronic Health Effects The following chronic (long-term) health effects can occur at some time after exposure to Titanium and can last for months or years:
    • Cancer Hazard According to the information presently available to the New Jersey Department of Health, Titanium has not been tested for its ability to cause cancer in animals.
    • Reproductive Hazard  According to the information presently available to the New Jersey Department of Health, Titanium has not been tested for its ability to affect reproduction.

    Titanium dust has a Kst value exceeding 300, far surpassing the explosivity level of polyurethane dust at 156 Kst. Despite these dangers, it's concerning to observe the use of ceiling-mounted Ambient Dust Collector systems in machine shops to manage titanium dust plumes. These installations are ill-suited for capturing explosive dust due to numerous inherent limitations.

    Capturing VOC from the Source by Scrubbing with Carbon

    The Challenge

    A major plastics manufacturer experienced heavy odors from mixing powders containing WALOCEL™ MW 15000 PFV Methyl Hydroxyethyl Cellulose.

    The Solution

    Our team suggested the PDB-VOC source capture collector. The dual 4" ducting collar version allows our client to connect static-dissipative flex ducts directly to the dual 4" pickup points on the mixer, ensuring a completely sealed source capture.
     

    Our experiments demonstrated that the most effective results were obtained when a combination of 4mm potassium permanganate pellets and 4mm activated carbon was used. The PDB-VOC Collector accommodates up to three 24x24x3" carbon cells, each capable of holding 28 lbs. of absorption media. This arrangement ensures thorough capture of the targeted powders, significantly enhancing the company's operational efficiency.

    The plant manager expressed great satisfaction with the PDB-VOC Collector, noting its effectiveness in improving their processes, which led to the recent purchase of a second unit.
