I think what you have written is worth noting.

However, I'm not sure that the elements for an explosion are present. The gas won't burn without oxygen. Small drops of molten metal -- even though they are of high temperature -- don't have enough heat content to raise the temperature of the canister to anything like bursting pressure. Could they melt through the canister? Probably not -- not that I'd really like to find out. If I had a melting flux ring, I'm sure I'd turn off the burner.

Although explosion doesn't seem very likely, what could be really bad is if a sudden move or bump caused the metal to spatter. While it probably wouldn't be a problem to the canister, it *would* be a problem on skin -- or clothing first and then skin. This would produce a very bad burn.

Thanks for the heads up. It would be nice to see if JetBoil has a response.
