Don't try this at home. I know a guy who had a shop, he survived the fire with 2nd degree burns. You've got to be really carefull when servicing your vehicle and have fuel leakage problems. He was trying to resolve the leak, dropped the trouble light, there were vapours on the floor and a flash fire. Nobody died, this time. The 4 bays were enveloped in minutes and burned to the ground with all contents. Vent your areas. Be careful, very careful when working on your fuel systems. The attached pic is of the welding bottles that came through the wall. The torn bottle opened a hole big enough to drive thru, the second bottle dented bouncing off the tree. Too close a call for one of the firemen! When he stopped shaking he told me he soiled his pants. Please be careful out there. Treat your flammables with respect and vent your work areas.

 

Dang, I'm glad no one was killed

 

X2 on that. When he heals up, in about a year, I'd like to give him a swift kick.
But known him for years and there is no changing some people.
Hope others can learn from the mistakes.
