Does anyone know what pressure is required to cause venting? With that info one could use the Ideal Gas Law to calculate the temperature at which venting would occur.

The vent pressure of most LP tanks is 250 psi. Some are built to a comparable standard and have a rating of something around 300+/- psi, but were intended for propylene service, not propane. I mention this only because I have seen those tanks repurposed by unknowing individuals and it causes an undue risk in propane service due to the higher relief valve setting.
I found a chart that shows that propane at 80 F will have a pressure of 140 psi. Using the ideal gas law I found that the temp would have to go to 500 F before the tank pressure reached 250 psi. That seemed high and even though the calculation is simple I used a couple of on-line calculators and got the same answer.
The chart is HERE and one of the calculators I used is HERE
So unless I did something dumb (that's always a possibility) it doesn't appear that an enclosed compartment, truck or car interior is going to get hot enough to cause venting.
