Storing small propane canisters in summer heat?

Next week I'll be driving through New Mexico and Arizona. In late July I'll be camping at Palo Duro on my way up to Colorado. For both trips I'll be carrying a camp stove. Will it be safe to leave the propane canisters in the (covered) bed of the truck, where it may get plenty hot? If not, how do y'all store canisters when you're camping or driving in summer heat?

 

Where ever I want. It takes quite a bit of heat to be dangerous. They are designed to handle about 120 degrees with no issues. I store full tanks in my shed in the heat of summer. Also my BBQ gets direct sun on the tank. My patio heater has a full tank and stays outside. We get over 100+ degree days here.

 

It can reach 150+ inside a vehicle in hot weather. There have been several documented cases of scuba tanks exploding in hot weather here in the south.



Happens to aerosol cans too.



So far the worst thing I've had explode is a can of Coke.

 

Never had a problem and I live in the desert.

 

A scuba tank would "explode" easier than a propane tank due to high atmospheric temps. I put explode in quotes because it's more likely the scuba tank ruptured due to expansion rather than exploded (i.e. ignition), although either can be as violent as the other. The flash point of LPG is 470F which would be almost impossible to reach without forced induction or convection of some sort so I wouldn't worry about propane in a hot vehicle or anything.

 

Uh. Nope..

Scuba tanks are required by the DOT to have burst disks. Burst disks need to be 5/3 working pressure. Working pressure of an AL 80 is 3000psi, so 5000psi burst disk.

A scuba tank would need to be heated to about 300degF to blow the burst disk at 5000psi.

Plus a scuba tank is not filled with flammable gas.
