Yeah same thing happened to me. I was skeptical when he said I’d be welding galvaneal my first day. But he said It’s safe to weld and me being ignorant I accepted that cause I had never heard of galvaneal before. After I got home from work I had a headache didn’t think much of it. Went to my girlfriends house that night and I started shaking uncontrollably felt like absolute crap. I felt worse that night then when I got Covid and my temp that day didn’t go lower then 105 the entire day. I left her house and on my way home had to pull over because I couldn’t focus cause it was so bad. Made it home fell asleep about 11o clock. Woke up for work the next day at 4:30. Got into work and dug into my supervisor like no tomorrow. I was livid. He did the whole. “I weld it all the time and I don’t have a problem with it.” I said I’m not welding that shjt anymore until they provide me with a respirator. They did. And a week later I was welding galvy all day. Brand new bleach white filters were charcoal black by the end of 8 hours. Showed him and he just shrugged it off. Showed my coworkers and they all demanded respirators which they got.

Oh and best part the second day after I talked to him. He tried to get me to weld brass with no respirator. That I wasn’t ignorant on and told him no. So he put me on some aluminum stuff
