Re Propane

Just because a flammable gas is lighter than air doesn’t make it
any less dangerous. Lighter than air gasses float up around the
light fistures, outlets and sometimes sparking moters. I suppose
the answer is to make sure to use tight fittings, use a minimum
of gas and be sure to shut things off when you leave. Personally,
we have been using propane for years in the same room as the
furnace with no problems. On a slightly different note, has any
body ever set their gas delivery hoses on fire with a casting or
welding torch? This I think would be a more real risk than using
propane.

Does anyone know of any lighter than air flammable gasses other
than hydrogen?
