Vacuum sealing propane canisters
 

Hi,

I know that those little green propane canisters can never be trusted
not to leak and should never be kept below decks, but what if they were
individually vacuum sealed and then placed in a ziploc freezer bag.

Is there an obvious mistake in this logic?

We do have a propane detector on board.

Thoughts?,

Mike.

Yes.

If the canister leaks, it will blow your ZipLock bag open.

Very true, just create a small on deck locker somewhere.

Yes. If the pressurized can leaks then it will more than fill the
baggy. I keep mine in a topside locker (isolated from the bilges) with
a low vent that will let any leaks flow out overboard.

I see some merit to that idea. After storing a bottle in such a way,
you would know immediately whether the bottle leaked or not when you
retrieved it. If you found that the storage bag had ruptured, you
would know to take appropriate steps to vent the storage locker. If
the bag was still sealed, you would know that the cannister didn't
leak.

I store three of those throw away cannisters in a piece of PVC pipe
secured to my Edson steering pedestal. The white pipe matches the
color of the steering pedestal, so it blends well and the material is
cheap and easy to work with. I have a small hold drilled into the
bottom threaded cap, so if a cannister leaks, it has somewhere to go,
into the cockpit which is open to the weather.

We have a canvas bag with a zipper that holds three of those cylinders and
it hangs on the pushpit right beside our Magma cooker.

Not cheap, but got mine as a gift.

Yes! Propane canisters have a BLOWOFF VALVE! Big tanks do too!

They're not "leaking"....they're blowing off excess pressure because
propane pressure depends a LOT on temperature and the blowoff valve is
there to keep the can from exploding, not from fire, but from PSI!

Look on a propane torch tank top. See that little hole that looks like its
got the guts of a tire valve in it? That's the excess pressure relief
valve! The aluminum cans have a popoff valve in them, too, but not
resettable like the propane torch tanks.

I use the taller, thinner torch canisters in a similar pipe
arrangement hose-clamped to the outer side of a stern rail stanchion.
They haven't yet caused any problems and drain overboard if they leak.
