It hazard not risk. If welding was a pesticide it would be bannedOh ffs. Yes welding fumes obviously presenting the incredible risk to yourself given how much welding you do compared to 10 blokes in a sealed factory all welding for 9 hours a day constantly for 48 weeks a year. I suppose he expects a fully equipped fume extractor rig for your open fronted shed and the 20 hours of welding you might do a year?
These folk must be nuts.
