During the processing of combustible raw materials, small particles of dust are created by the processes of blasting, crushing, milling, or grinding. These particles are often too small for the human eye to see. The dust particles made up of combustible materials are more dangerous than the combustible material because their size contributes to an increase in surface area. This inBuilding a healthy weld shop starts with cleaning the air itself. Whether your welding team is working with arc or gas, there are dangerous gases and dust particles released in the welding process that must be filtered continuously to protect your employees from exposure.
Dust collectors used in the welding industry must gather extremely small particles to reduce contaminant buildup in the air and protect expensive equipment from damage caused by dust settling on and clogging up delicate mechanisms. crease poses the risk of explosion because the dust has more surface area and burns faster.
The risk of explosion in a work environment is brought about by the high concentration of dust in surfaces as well as in the air. As time goes by, specks of dust begin to accumulate forming several layers in the atmosphere and the surrounding surfaces. If the dust is ignited, there is a risk of enormous explosions that can be fueled by the high concentration of combustible dust that is ready to ignite and burns at a fast rate.
Systems for dust extraction must then include:
- directional air movement, to keep particles airborne
- minute filtration capacity
- easily accessible filter materials for easy and safe change-out
It should be noted that the direction of air across the welding surface must offer your skilled staff constant access to clean air and a clear field of visibility.
Disposal of Filtered Particulate
The process of cutting and joining metal via heat can cause the release of flammable particles. Your industrial dust collector design must include easy access to filtration cartridges designed to capture and safely neutralize these particles.
Your business leaders will likely need to devise a schedule for the safe handling and removal of filter materials. The welding industry is an ever-changing business with continued access to increased technological efficiencies, but safe handling and removal of these filters, once exhausted, must be scheduled and extraction techniques formalized and followed.
Designed for Efficiency
Depending on the shifts run by your welding team, your dust collection system need not run 24 hours a day. However, when it is needed, it must function effectively and efficiently to protect your workers and equipment.
Design professionals at Teldust are ready to work with you to help design and build a system that will effectively supply your welding team with clean air, free of welding fumes and dangerous small particles for the duration of their working shift. There will likely be a continued filtering for a time after the shift to confirm that all contaminants have been removed from the area before shutting down for the day.
Dangers to Consider
The dust collectors used to protect workers from welding fumes must offer minute filtration and be easily disposed of with minimal contact. The process of welding releases gases containing many dangerous metals, including arsenic, lead and aluminum.
The gases that your dust collection system will need to capture include carbon monoxide and hydrogen fluoride. In addition to the poisoning possible in welding gas exposure, some gases released during welding can displace oxygen and cause suffocation risks.
Determining the best dust collection design for your existing welding space will take a customized approach. Depending on current airflow and power access, your dust collection design may require a careful study of each worker’s area to keep air flowing out of their physical working space.
Due to the vagaries of weather and wind speed, even welders working outdoors can’t be guaranteed protection from dangerous dust and gas exposure. In addition, even with proper drafting, welding spaces can’t be confirmed as safe workspaces. Finally, without proper filtration of welding dangers, even a space with perfect airflow can spread toxins to other living creatures near the workspace.
Options for Fume Extraction
Depending on your welding type and set up, there are several spots along the welding process where fumes can be extracted. These include:
- Extraction at the torch. Depending on the type of welding you’re doing, you can remove fumes directly at the torch. This extraction requires a ventilation unit be attached to a flexible torch tool.
- Flexible Extraction Near the Torch. We can help you design a fume collector with flexibility so your welding team can move the extraction tube exactly where they need it for safe air access. These filters draw fumes directly up into the primary air cleaners.
- Portable fume extraction. If your welders have to go where the work is, these units can easily be moved around the workshop. These units are self-contained and offer flexible arms for safe positioning of air movement. In addition, these units offer self-contained filtration for easy filter removal and disposal.
- Cutting tables. Weld shops with plasma cutters will appreciate these capture tables featuring a dust collection tool built right into the cutting surface. These tables offer a stable and safe workspace.
Investing in a safe weld shop keeps your employees healthy and your business growing. No matter the size of your shop, we can help you come up with an industrial dust collector design that will protect your employees and critical equipment from the risk of dust exposure. We are excited to help you create a safe and productive workshop. Contact us for a consultation!
