“Notice how most of these deaths occur at unionized facilities?”
What do you mean by that?
Simple - almost all of the fatal disasters have occurred at facilities being operated by protected, dues paying, union workers. You don’t see this kind of thing much when the unions are on strike and the facilities are being run by managers and scabs.
Give management a free hand to get rid of goof offs, jokers, and chemical users, and the safety situation would probably improve. The Union’s proposed solution, of course, is ‘don’t make us work as hard and pay us more’.
