The same might be said of the 13 oz propane torch bottles that nobody,
including the fire department, worries about indoors. My lifetime sample
size of a few dozen bottles has displayed a few slow-leakers. Or you just
don't turn the torch off properly. One of those bottles, plus the spare in
your toolbox, is about the same mass of propane to charge an auto air
conditioner.

You might want to consider the limits of flammability for propane in air.
It takes quite a stroke of luck to get the right proportion from a given
leak rate or given volume of enclosure. The hazard would seem to be quite
comparable to a gasoline fuel system leak.

Propane indeed has its hazards and should be respected, but being
superstitious about it is imprudent.

Anhydrous ammonia has been used in residential refrigerators. Propane is a
kitten compared to that stuff.

Not likely. Only in certain narrow limits, 2 to 10 percent for propane. A
proper burner is actually quite hard to design.

You know what, I have seen a whole bunch of blown campers from propane
and have friend that lost parents from a propane bottle in the back seat
leak, know folks that survived one with the top of the camper opened
like a sardine can, deaf and burned, but alive, so the odds aren't
'that' bad.....

I'll bet if you Google hit it there would be lots too.
