Thanks for the info David, I am glad it all ended relatively well. I have entertained the idea of buying a portable oven for kayaking trips before.
Some years ago, a friend of mine left two new canisters in his car. When he came back from his multiday trip he found one canister popped its bottom while the other one exploded. The explosion destroyed clothing and shoes and did some damage to the trunk. The car was parked in the sun during a heatwave and my friend estimated that the temperature inside the trunk might have reached 140°F, perhaps more (the car was too hot to touch on his return). Since then whenever I need to leave a canister behind at trailhead I stash it somewhere outside. Perhaps a bit paranoid but I think it is better to be safe than sorry.
I am not sure more warning labels will help, it is a dirty secret that the warnings are not read by people who might benefit from reading them. As a graphic designer I have been invovled with outdoor and fitness products and it is largely the legal department that insists on these warnings as a response to past incidents, i.e. to protect the company first and foremost and then, maybe, inform the consumer.
Whether the gas stoves are safer than the white gas stoves (or any other camping stove) remains to be seen. But I do know all of them have a safe window of operations and if that window is not respected a problem will arise. Unfortunately there are many things that come into play including ambient temparature, wind, air pressure, the equipment itself to spell out all the possibilities.
I think your post, your sharing the experience will help more people than any warning label might. So thank you for that!
