Right on Bob. I walked into the shop today to see one of my co-workers welding up an inner quarter on a Subaru. He had no fan on, no respirator, and he was inside the car that was full of smoke, this is ZINC on a late model car, weld thru primer is ZINC, all panels on a late model car are galvanized, and here he was breathing a LOT of ZINC fumes. Fumes= "A dispersion of solid particles in a gas. Fumes are often produced from high heat, such as during welding."
He was BREATHING ZINC! Zinc particles filling his lungs.
I had to go get a fan and he still didn't want it thinking it would suck away the shielding gas!
Damn this life is so wonderful, I am going to do anything I can to lengthen it, not shorten it. Taking a chance for an experience like sky diving, that's one thing, but breathing Zinc when you don't have to, come on now.
