Welding Fume Extraction System in Confined Spaces
Welding Fume Extraction System in Confined Spaces What is a confined space in an industrial setting and why is a fume extraction system a critical device? Any space with constrained access with limited means of entry and exit are called confined spaces. Ventilation is normally poor or very limited, oxygen supply is low, air contaminants are present, and traces of toxic or flammable gases are found. The dangers present in confined spaces can put any person in harm’s path. Oxygen shortage is a major problem. When there is limited access and oxygen supply is low, respiration increases while more carbon dioxide (CO2) is released. With more CO2 being released in the atmosphere, oxygen levels drop down. This endangers the life of the people within the confined space. There is also a risk of explosion due to toxic or flammable gases stored in confined space. Lingering flammable vapors inside a tank truck or cargo or welding gases in a metalworking shop can cause fire or explosions t...
