You gotta love some homeowners: Low pressure water line to run a gas appliance by feeding natural gas to a propane unit. Love how they run the low pressure plastic line near the base of the hot water heater burn chamber.
I saw a television show on some of the HD channels the other night that showed industrial gas explosions.
One was a recent incident in Tacoma that I felt as I was eating lunch in a restaurant about a mile away from the explosion. The lights flickered and the ground shook. My first thought was an earthquake.
A large propane tank had gone off,
The driver of the tanker died from burns and several others were seriously injured.
Just happend on last Thursday. They have identified the dead man, but have not established why he was in the house. May have been stealing copper. Or maybe installing a new gas appliance@!
Note that the garage door is some 30 feet down the driveway near the street. All the windows on both floors blown out, even before the fire destroyed the house totally.
