That scenario used to be taught as the way manufactured gasses like
propane behaved but experience has shown that is too simplistic a

I watched a movie where the bad guy placed a lit candle on top of the
fridge and then loosened the hose to the gas range just a little bit.

He was long, long gone before the gas reached the level of the candle
and ignited.
