A slow leak is a much worse explosion. It is all about involving as much volume of fuel air mix as possible. If you insert the gas into the HVAC system it is a lot more effective than just breaching the tank in one room. That is simple middle school science. Maybe I am more aware of this because I heard a house go up when I was a kid and there was nothing left but the 1st floor deck when we got there. Pieces of the house were spread out over a whole block. Everyone in the house died. The FD determined one stove burner was on simmer. I live in a *very* rural area right now. Last year around July 4th someone shot a 20 lb propane tank with a gun in a field about a half mile or so from my house. The explosion was deafening and we and all our neighbors felt our houses shake. A lot of years ago a guy in Oakland decided to commit suicide. Turned on the gas with no pilot lights. He slept through the night and forgot about the suicide attempt. Got up in the morning and decided to light the stove. House blew up just like you described. My buddy worked across,the street in a car repair shop. Their windows blew out. He and his coworkers escaped injury and the guy across the street escaped most injury. Jim said the guy was standing in the middle of the explosion with the match still in his hand. He didn't smell the gas? Have no idea. Maybe he was stupid as well as suicidal. |

It is possible that if he slept through the buildup of the gas he might have gotten used to the smell. Bill didn't say whether he was hurt. Being right in the middle, it is possible he may have escaped much more than some burns. The people in the house up the street from me were on the second floor when it went off and they became part of the debris field. |
