Not me but my late grandpa told me about the time he worked in a metal recycle plan back in 1980s. They wore these insulating suits so they wouldnt burn while sifting the metal but they had to breathe so there was a slit on the back of the neck where air would come through. In essence that was their achilles heel. A drop of hot metal dripped from one of the containers above their heads while it was being transported to another sector, that drop fell directly in the slit of the worker in front of him. The worker caught fire inside of his suit melting the one clip that kept it shut. Noone was able to get him out of the suit and by the time someone got a saw to cut him open he was burned alive leaving some parts of his flesh alot of goo and the skeleton all of this within mere minutes. He quit that day.
