I had a long inch and a half round bar I was cutting with my acetylene torch, the cut end dropped off, I picked up the bar no where near the center and it instantly slid in my hand. The glowing red end hit the meaty outside edge of my hand, that was an instant trip to the ER. I ended up with a huge third degree burn that took months to heal, the burning pain lasted weeks. Bought a pair of heavy duty welding gloves after that.
