I would be more concerned about the safety release that is built into every cylinder. At a certain pressure, the safety release opens and a large volume of both gas and liquid is expelled. It happened to me, once. The cloud emitted is so dense that you can't see your outstretched hand.

This is not true at all !
Did you dream this ?? If this really happened, you had better get it fixed quick, because this could make for a very dangerous situation.
In reality, a LP safety release valve releases the LP gas no faster than the gas is expanding and needs to release, which is seldom more than a hissing sound that can be heard and smelled when close by. It presents absolutely no hazard as long as there is no open flame w/in 50 feet.
It is not a pop off valve, such as found on an oxygen bottle, that really will expel its entire volume if it gets over pressured.
It is a bleeder valve, and will NEVER bleed off more than needed for expansion.
The cause of the cylinder venting was an inexperienced hand at the fill station. He overfilled the cylinder. When underway, the pressure built and the cylinder vented. After arrival at our destination, with the propane cylinders in a compartment on the truck camper, another cylinder vented in the same manner.
