Next message: Rich, Michael: "RE: lv-ab: Another Propane question"
Propane is heavier than air, but it is still a gas, so any movement of
the air will blow it around, just like gasoline fumes or the air
itself. Any place, like a propane locker, that is exposed at least
somewhat to air movement, should not build up any amount worth worrying
about.
But the bilge can be a problem if it is all sealed up so no air can get
to it. Many boats have a vent that brings air into the chain locker
forward, then down through the bilge and out somewhere aft. Any such
arrangement should keep the bilge fairly clear, but things can happen to
prevent it from working, like blocked vents, no wind, etc. A bilge
blower is one good answer to that. Bottom line is, make sure the bilge
gets some air moving through it periodically, and that should keep it
clear of small amounts of leakage.
In addition, I would definitely install a gas alarm in the bilge if I
had propane or gasoline on board.
