At-source extraction protects workers in the metal industry and prevents the accumulation of welding fumes, oil mist or grinding dust in the workspace. The use of flexible extraction arms is a good method of removing dangerous fumes and dust when working on small or medium sized objects. These arms can be positioned close to the work area to capture toxic fumes, dust particles and remains of molten metal at the source. Capturing fumes and dust at the source also prevents pollution from spreading over the premises, keeping not only machines and tools but also products and offices cleaner.
In previous blogs we have written about protection methods for welders, like extraction arms or hoods for local exhaust ventilation and welding helmets with PAPR units. When you provide your workers with protection equipment, you may think that you have taken the necessary steps to ensure their safety. But how can you be certain that the equipment is working as it should and your workers are not exposed to dangerous levels of carcinogenic fumes?
When metals are heated above their melting point, they vaporize and condense into welding fumes. Most people know that these welding fumes are unhealthy and dangerous. Although not everybody in the metal industry – and in other lines of work where welding is done – is fully aware of the dangers, most of them are familiar with local exhaust ventilation and personal protection equipment to minimize the health risks that are involved with welding.
Welding fumes and UV radiation from welding are now classified as “carcinogenic to humans” by the IARC.
Over the years, modern diesel engines have become cleaner. Or in other words: they have become less pollutable and emit less hazardous fumes. Diesel engines even emit less carbon dioxide than gasoline engines and many diesel engine manufacturers claim that most of the harm of diesel exhaust has been reduced.
Metal fume fever is a benign, self-limiting occupational respiratory disease that results from the inhalation of fine metal particles. Whilst the exact mechanism for this condition is not known, the primary cause is thought to relate to the inhalation of zinc oxide fumes produced when zinc-coated steel or zinc-containing alloys (e.g. brass) are heated to high temperatures. A variety of other names for this condition is used, such as copper fever, brazier’s disease, welder’s ague, foundry fever, brass chills and spelter shakes.
Fire stations and related public works service facilities can rest assured that Plymovent HT hoses will keep fire fighters and vehicle service personnel safe, and systems remain in good use and functional.
Plymovent announces exclusive distributorship with Fantech Pty. Ltd. for Australia and New Zealand.
Last year, leading US firefighter advocate Billy Goldfeder wrote an article on the importance of having compatible systems among fire departments with automatic or mutual aid agreements:
Welders must be protected against hazardous welding fumes. Depending on the welding environment or how and what is welded, welders can be protected by systems for source extraction and general filtration and ventilation. Also, they can be protected by respiratory protective equipment (RPE), such as welding helmets with fresh air supply. Supplied air respirators are known to provide the best all-around protection for the welders themselves
