The Environmental Protection Agency (EPA) is an independent agency in the United States entrusted with the mission of protecting human health and the environment. They dedicate themselves to topics as diverse as air, water and land, chemicals and toxics, waste and cleanup.
What is hexavalent chromium & how to act for best protection.
A recent case (early February 2019) of financial compensation for 800 workers who have been exposed to the hazardous hexavalent chromium in the workshop of the Nederlandse Spoorwegen (NedTrain-department) in Tilburg, the Netherlands, has again put the spotlight on the danger of this substance.
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.
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
Nowadays, everybody knows that welding fumes are very dangerous and that all kinds of protective measures should be taken and respected during work. In other blogs on this site, you can read more about those dangers and risks. But is everybody really aware of the importance of those protective measures such as PPE and local exhaust ventilation? The answers of welders themselves are surprising…
In buildings where welding is carried out, temperature control and problems of airborne contamination are important, and the provision of clean air increases. Although fresh air is usually supplied by general ventilation, the sole use of general ventilation for airborne pollutant control in welding is usually ineffective.
