People love to get stupid around that stuff too. I went to do an overpack job at a chip plant once and they had a glass jar of sodium cyanide sitting 4-5 feet off the ground in the acids storage spill containment area. If they’d spilled acid in there and knocked that off into it, lights out...
I remember seeing a gas chamber execution, maybe on Twilight Zone when I was very small. Black & white. A little bowl of acid underneath and behind the strap in chair, a little handle sticking out holding a gauze wrapped package. Guy outside presses a button, the handle drops the package into the bowl, and the fumes start coming out.
OMG, had nightmares for years about that one. Sure and it couldn’t put put on today.
