I worked on OSHA policies for a number of years. It’s amazing how little worker protection existed just a generation ago. My dad died of a degenerative disorder after a career of working with solvents and petrochemicals and metals. Nothing that would be considered exotic, just the stuff you’d find on a regular machinists bench and mechanics station way back when mechanics were equal parts fabricator and did a lot of grinding, soldering, welding, etc. They didn’t wear masks, or cover their skin. Hell, he used to clean the grease off his hands with some solvents. Did it cause his illness? Who knows. Three of his close friends died of cancer, and most of those products they used would have specific handling instructions today or have been outright replaced.
