Do COSHH regulations apply to welding?

Yes, absolutely. COSHH applies to any process that creates harmful airborne contaminants, and welding is one of the most common examples. Since welding fumes are now recognised as a carcinogen, COSHH requires a more robust approach, including LEV, safe working practices, RPE if LEV alone isn’t enough, and proper training.

A COSHH assessment for welding should cover the method used, the metals involved, exposure time, ventilation, and any risks from gases generated during the process.
