Or worse, the valve gets cold enough that it freezes open, which is a super scary scenario if you are trying to contain a leak.
Propane is one of those fuels that both demand respect and punish poor treatment. It’s not as merciless as, say, acetylene (It’s more stable for starters), but there’s a reason most firefighters call the standard 20 pound tank of propane a barbeque bomb. (I’ve been calling the smaller 1 pound cylinders grenades, but that’s just my sick sense of humor.)
