Dont laugh

Back when I was 20 I was welding at a production welding shop (GSI) and we had a new guy (in his 30's) start on. On his 2nd or 3rd day he was paired with me as we were to weld out a piece that required a guy welding inside and another outside. It was a collar that beams bolted to at the top of a grain bin. And to top things off it was all galvanized, so it was reflective as well.

He said he would weld the inside and climbed in wearing just a tank top!! I stopped him and said he should probably put on a jacket or sleeves or something. He just brushed it off and said he's done things like that before.

Needless to say, he didn't show up for like a week after that and when he did, his shoulders were nearly black and were all bandaged up. He quit a few days later.
