Guy who was on top of the bins got 3rd degree burns on 50% of his body. He has had 7 skin grafs since then and is doing better. We have alot more safety standard in place now to prevent the same thing from happening again. Happenend at my shift change I was in the locker room down stairs when the fire ball went up. they cleared the building out for a while to make sure all was safe but saw the burn mark on the inside of the roof from the fire, was huge.
