Fire Tetrad Theory

The Fire Tetrad Theory explains that four elements are necessary for a fire to occur: heat, fuel, oxygen, and a chemical reaction. Heat raises the temperature of the fuel, allowing it to combust. Fuel can be any material that can burn, while oxygen, usually from the air, supports the fire. The chemical reaction is the process of combustion itself. If any one of these elements is removed, the fire will go out. Understanding this theory helps in fire prevention and safety, as it highlights the conditions needed for fire to ignite and sustain itself.
