Thank you for posting that. That pretty much confirms the experiences I've had with the stuff. It is not foolproof, but it's about as close as you can get with a portable open flame heat source. It is much safer than any propane heater or the like. About every other year during deer season somebody leaves a propane heater going in a camper or a tent, and they wake up dead from CO. I have yet to hear that happening from Sterno.

That's a good point about the generic sterno as well; it may well have a different composition. Another thing to watch out for.
