A few comments here mentioned that old ships being broken up have a lot of asbestos. I would have assumed this would have been an issue on very old ships, but some cursory web searching suggests that it's still prevalent even in relatively new ships. IMO rules ( https://www.imo.org/en/OurWork/Safety/Pages/Asbestos.aspx ) say roughly that: - Ships built before 2002 may contain asbestos, but it should be "managed prope…
Maritime regulation is hard when it operates in the space between states. Asbestos in particular is such a temptation in manufacturing because it's just so useful and cheap. An argument can probably be made that handled properly it saves more lives than it harms just because it's such a good fire resistant insulator.
