7. Health and safety

Like all arc welding processes [BM 7 700] , MIG/MAG welding involves risks:

• gas: formation of ozone, nitrogen oxides and carbon monoxide in the arc (respiratory tract irritation); argon-based protective gas (asphyxiation in confined spaces);

• radiation: ultraviolet (burns and cancer), infrared (overheating) and visible (glare);

• dust: metallic particles and oxides (respiratory tract irritation and long-term illness);

• electric current: risk of electrification in...
