Welding fumes
Welding processes can generate fumes which are tiny solid particles and gases. Inhaling these fumes and gases can pose long- and short-term health risks to workers.
From 18 January 2024 the workplace exposure standard (WES) for welding fumes (not otherwise classified) has been reduced from an 8-hour time weighted average of 5 mg/m3 to 1 mg/m3.
Elements found in welding fumes can include iron, manganese, chromium and nickel. When these metals are heated to high temperatures, they vaporise and can form tiny particles that float in the air. Gases are also formed by the UV radiation from the welding arc.
Welding fumes and UV radiation are classified as group 1 carcinogens. Learn about how to reduce exposure to hazardous welding fumes and UV radiation in this video.
