text: Without air, oxygen, and fuel, as rightly as someone has posted as an answer before me, a fire is nonexistant. A fire is the chemical reaction itself caused by those materials.\n\nThere is no such thing as fire without air, oxygen, or fuel.\n\nP.S. Perhaps there is some laboratory special fire made with a different fuel or something, but other than that, absolutely no possible exceptions.\n\nNice question.
