Fire ignition requires three components, commonly referred to as the fire triad: source, fuel, and an oxidizer. At the molecular level, a fire is a chemical reaction of a fuel plus an oxidizer that produces heat and light. It has been estimated that annually in the United States, there are 50-200 OR fires. To improve patient safety in the OR, the American Society of Anesthesiologists has issued a practice advisory on how to prevent and manage OR fires (Figure 35-1).
