Next message: Rich, Michael: "RE: lv-ab: Another Propane question"
I know propane is heavier than air and finally sinks into the bilge, but just
how long does it remain there? Does it accumulate each time a little bit
escapes from a burner, or does it eventually dissipate into the atmosphere?
If it does dissipate, how much time does it take before you don't have to
worry about it? Hours, days, weeks? The reason I'm asking is that often
when I light a burner or the oven, it sometimes doesn't light right away, or
the lighter goes out, or the match burns my fingers and I drop it before the
oven lights, etc. Also on occasion when disconnecting the supply line from
the tank, (particularly the barbacue supply line) a significant amount of gas
comes back through the supply line. The locker does vent overboard, so I
don't worry too much, but the vent is about a 1/2 inch above the absolute low
point. I assume that at some point the propane that collects below this vent
mixes with air and becomes harmless, but the question is how long does this
take, or is there forever a risk at the bottom of the locker? We do intend
to get an alarm when the kitty permits, but in the mean time just how
paranoid should I be?
