Better you than me, I already went through having a pressurized
-non-flamable container go off on me, and certainly would not want to
even consider a container that held propane no matter how small of
ratio of gas to air it had. Its certainly not worth my life or limb to
take such a chance.

I have taken them out before and have never used heat.
