He probably learned the hose trick on the first one he welded! I once worked in a Toyota Shop and we had an underground waste oil storage tank. Right beside the back overhead door, there was a basin that we poured our roll around drain buckets into, with a sludge separator. You poured in the oil and it overflowed into the pipe that went into the tank. We ALL used these roll around's to catch the gas when we changed fuel filters mounted under the cars. One day the door broke and the overhead door company guy came and had to replace the side track which was bolted to the wall. He proceeded to climb up a 12 foot ladder and start cutting the bolts off with a torch. The slag dropped right into the sludge tank that had a little gas floating on top (it had been a real busy day). I heard a boom, looked over and saw a ball of fire run up the wall, over the guy, and 30 feet or so down the ceiling. The guy fell off the ladder and was burned and hurt, and went to the Hospital. The day before this happened, we got some signs sent to us by the oil or Insurance company warning anyone not to use open flame around the tank, the shop forman hung it up on the wall right above the tank. When the fire and OSHA inspectors arrived, they saw the sign and we were off the hook. One day saved our shop a big fine. Usually signs like this lay on someone's desk for months.

A guy came out, took a torch and cut off the old cap and welded on a new one. The trick was that he first put a hose down the pipe shaft from his exhaust pipe on his truck, filling the void in the tank with carbon monoxide. With that, no oxygen, no danger of fire.
