My propane heater has no open flame at all. You cannot get a severe burn from it and you cannot light anything on fire with it. If it tips over or something falls on it it will not catch anything on fire. It will even shut off and go out. Plus it gives off no toxins when it burns because of the type of element it uses and can be used safely in a small area with no health concerns.

I don't want to imagine what would happen if you tipped over one of these things and a flaming roll of TP rolled across the floor in a blind or in the brush. And God forbid if it actually had liquid in the bottom of the can. And I don't think rubbing alcohol burns that clean either that I would want to breath it.

The only way you are going to have a problem with a propane heater is if you puncture the tank, which is pretty darn hard to do. Much harder than having an accident with a burning accelerant in an open can.

I'm not saying it doesn't work or is not cheap. I just don't think it's the safest way go about it. My blind is 14 feet in the air, made out of wood and has carpeting. Not to mention I have black powder in there. I wouldn't try using that in my blind for sure.

Just my opinion anyway. However I will admit I have done dumber things in my life.
