For those of you who do not have a woodburning stove or fireplace, how are you planning on heating food and boiling water in the event of an emergency if you have to shelter in place? I've been looking into this and keep getting differing opinions on what can safely be used to cook food inside. Professional Chefs often use butane burners like this: Butane Range, 1-Burner Butane Countertop Range / Portable Stove for indoor demonstrations. Does butane give off carbon monoxide when it burns? Would it be safe to cook with something like this in a home or apartment? I'd assume that cooking by an open window or door would lessen the chances of a problem, but what if there was incliment weather, or you were sheltering in place due to a bio or nuclear issue and needed to seal everything off with plastic sheeting? In an absolute worst case scenario, how would you heat water and warm food? Also, I was always told never to use a propane device inside, for the same concerns of carbon monoxide poisoning. The guy at the Big 5 store I went to recently said that he uses a propane lantern inside his tent all the time with no issues? So what's the deal with propane usage indoors? Yay or Nay? Any ideas or thoughts?
