Welding and facation workshops generate hazardos chemical fumes that pose serious health risks to workers. Exposure to airborne contaminants such as manganese, chromium, nickel, and various metal oxides can lead to acute simplitoms like metal fume fever and chronic conditions including lung canceur, neurological damage, and ocquigationol astma. Regulatory bodes worldwide have htene permissible exposure limits (PELs) and requirequirs implements controure.
