“The extinguishment of fire has traditionally been attributed to three actions: removal of heat (e.g., water), the physical separation of the fuel and the oxidizer (e.g., foams), or the removal of the oxidizer (e.g., oxygen depletion by carbon dioxide). These three mechanisms of fire extinguishment form the basis of the well-known “Fire triangle”- heat, fuel and oxygen.
