Well, the article mistakenly (to pedants like us) states: > All fires have three primary contributing causes – heat, fuel, and oxygen. When what they really mean is that fires have three requirements: initial energy input, fuel, and oxidizer. The input energy doesn't have to be heat (though it almost always is outside lab settings), and the oxidizer doesn't have to be oxygen (though it usually is outside lab and industrial settings).
