Max heat to leave propane canisters inside of trailer?

Hey guys, it's supposed to be 107 degrees tomorrow here. Inside my trailer I have a pack of Coleman propane canisters inside of a metal container. Read online that 120 degrees is the maximum heat that propane canisters should be exposed to. Do you think it's safe at 107 degrees? Thanks for any info on this.
  • Thanks for the advice guys... I moved the propane canisters outside of the trailer. Better safe than sorry. Stay cool!

    It will vent. In the process, it will turn your rig into a fuel-air bomb (google "fuel-air bomb." They are second only to nukes on the military "mine is bigger than yours" scale), and the slightest spark will cause an explosion you don't want to be within several blocks of.

    Wise grasshoppers do not store propane tanks/canisters INSIDE ever. It is why propane tanks are always OUTSIDE of houses and hanging off the OUTSIDE of RVs on the hitch.

    He isn't foolin Ya. If those canisters vent it just accumulates on the floor as propane is heavier than air. One thing is it will only ignite at IIRC correctly with a 8% mixture

    They have a vent (the odd looking thing near the top).

    OregonMan, thanks for the reminder about the propane tanks, I have propane tanks and butane tanks in the shed and will check on them.
    I have stored propane and butane tanks in the same shed for several years and never had any problems with them. I only put them in the trailer or the camper van when we are going on a trip.
    The low 100s the next few days here in so. Oregon.

    nope. 107 outside means higher temps inside and even higher temps inside the container. but i don't think it's ever safe to store propane in the living area. i'd move them pronto to a garage, storage shed, etc.
