How to properly wear and make use of a gas mask and protective clothing. You might think that's a funny thing to say but believe me, it wasn't funny at all. We had guys dying of shit like skin cancer and others getting pulmunary fibrosis and other respitory diseases.
The worst part was I was the only one showing up to work protected and my boss ultimately gave me an ultimatum, either ditch the protective gear and gas mask or find myself a new job. Naturally, I told him I quit, gave him "the finger", told him he had the skeletons of dead good men in his closet, and got my ass the hell out of there.
I believe he was prosecuted for not complying with NY state and Federal Government law come to think of it.
