Alcohol is already a poison - seriously, it is poisonous to the body. That doesn't keep us from drinking it however. Too much water is also poisonous, however, it is very difficult to intentionally drink too much water....

I don't worry about poisoning from burning denatured alcohol. I do worry about teflon poisoning at home. It's far more likely to be poisonous to me than burning some chemicals out in the open air.
