[quote=SmellsFeeshy]The valves on modern propane tanks won’t let the gas come out unless you have something connected to them. I’m sure it might be possible to drain out the gas but it’s not as simple as just opening the valve.
I’ll probably just end up giving it away like you suggested.[/quote]
I think you’re being paranoid. In fairness, I did the same thing when I transported a propane tank once. I later realized I was being silly; the tanks are really tough, and RV’s carry them around all the time. The tanks are tougher than your car’s gas tank, and the propane is actually safer because it rises into the air if it is released, whereas gasoline puddles on the ground and evaporates into flammable vapors. Any crash that ruptures your propane tank will be really bad news for everyone involved.
One reason moving companies prohibit them is not because of the potential of explosive release but because the tank would be in an enclosed space, so if it leaked slowly, an explosive combination of gas might develop.
It’s also a cheap tank, so just leave it as a baby on a tank exchange place’s doorstep.
Maybe Home Depot would take it and let you pick up a fresh one at your destination.
