Fiberglass insulation.
Everyone knows that you don't want asbestos getting into your lungs, but there seems to be a prominent disregard for basic safety in preventing inhilation of fiberglass for people who work with the stuff because it's "better" than asbestos.
Generally you don't want to be breathing in any kinds of particulate, but fiberglass is literally fibers made of glass. You are breathing in shards of glass.
I don’t think I’ve ever seen someone working with fiberglass and not wearing a mask. Do people really do that?
Yep. I worked a cnc table cutting fiberglass fabric for sailboat manufacturing. I was told the mask or ventilator thing (had filters and they tested it with smelling salts - I don't recall well) was only required when it was cold, because that apparently made the fiberglass worse for you. And that requirement was really just a suggestion.
This was also Florida, US. So... You know.
