There are many different types of welding processes, all which produce a variety of hazardous gases. The gases generated and their concentrations depend on the process used and the gas formation mechanisms. Common gases produced from welding are carbon monoxide, nitrogen dioxide, ozone, hydrogen chloride, carbon dioxide, nitric oxide and other gaseous fluorides. The health hazards from welding gases are asphyxiation, fire, explosion and toxicity.
Removing the air contaminants from the welder’s breathing zone is achieved by a well designed and maintained ventilation system. A fixed gas detection system can be installed to continuously monitor the levels of hazardous gases to help protect the welders and workers from exposure and risks to their health, providing a safer working environment.
