You're dealing with a lot of variables. A few weeks ago in Knoxville a house blew up due to gas. I mean as in nothing left gone. No real warning and two of the residents were asleep and were blown out of the house and survived. Their son who likely must have been the unfortunate one to trigger the spark when he came home didn't make it out alive.

Gas can concentrate in lower areas like basements, air ducts, etc, and blow a structure sky high with nary a sniff of foul odor noticed.

But where is the drama, the first cop smells gas, tells all the union employees to not go in, he turns off the meter as everyone in earthquake country knows how to do (the wrench is usually chained to the meter) and they wait for the plumber to show up.

You are wrong by the way, this is natural gas, not propane, natural gas wants to get away, not puddle, and it stinks to high heaven.

Natural gas is mostly methane, lighter than air, and it is somewhat difficult to blow up a building with it. Propane on the other hand is heavier than air, fills basements and crawl spaces, and then blows the building to flinders. I’ve been looking for a chance to use flinders in a sentence.

That happened to two houses about a half mile away in our neighborhood when I was a kid. I think three people died. Two good-sized suburban houses were leveled by the explosion, and a third damaged so badly it had to be leveled, too.

I was at school, but my parents happened to be home, and they said insulation rained out of the sky like snow. And, again, we were about a half mile away.
