It's pretty easy to get injured in spite of safety gear. There are the minor cuts, scrapes and splinters one might experience when dealing with (literal!) tons of broken glass, to say nothing of the times it breaks in your hands. And I was grateful to work on the tempered side. Raw glass breaking when handled is terrifying.
I personally gave first aid to someone whose wrist was slit open by glass. After the ER airlifted to a bigger hospital for reconstructive surgery, he at least retained most of the use of his hand. Note that everyone was issued Kevlar wrist guards (not to mention the jackets, goggles, etc.), so it's not like we were unprepared for such injuries.
Another plant had someone crushed under a forklift just before Christmas when it tipped over when they were emptying a glass hopper. Yet another plant had a sheet of glass break when two people were carrying it. It was raw. It cut open the person's neck and they died. One of the machines used to be called a 'Gas Chamber' (it was used to fill IG units with, e.g. argon). I'll let you guess what sort of incident made them rename that one...
I'm sure there are many more such stories, but I'm including only those I know about directly. There were many other issues as well, I don't have a complete list. I'm deliberately leaving out those issues that could be fixed merely by spending money.
If manufacturers cannot afford that level of compensation, or cannot afford to automate the risky kinds of labor, then they cannot function, and that's a good thing, because if they can only do so now because they are allowed to externalize the costs to society of their health hazards, then they don't provide a net utility to society.
I'd be glad if crappy industrial jobs could be made less so, but if suddenly computers are no longer affordable to anyone due to the inability to find anyone willing to work in the myriad industrial processes that feed the semiconductor industry, I'm not sure that society will actually progress as a result and perhaps there could be less socially disruptive ways that better achieve the goals of basic income.
