In another life I sandblasted heat exchangers in power plants and oil refineries - the first refinery I ever worked in had pipes overhead wrapped in asbestos insulation. It was all very well marked and had plenty of warnings to not go near it unless authorized and properly protected. Honestly though, I was crawling into a hole I could barely fit my body through to blast out thousands of pipes which flow liquid sulfur through them, with a grit that should the blast hose split was under enough pressure to inject sand straight through your heart, while wearing a sensor on my hard hat that I was told if it starts to beep I had 60 seconds to climb up out of the hole before I’d be dead. Asbestos exposure wasn’t a worry I had in those places, because everything else was trying to kill me too but much more urgently.
