Fire Triangle

The fire triangle illustrates the three essential elements needed for a fire to start and continue burning: heat, fuel, and oxygen. Heat provides the energy to ignite the material, fuel is the combustible substance, and oxygen supports the chemical reaction of combustion. Removing any one of these elements will extinguish the fire. This concept helps in understanding fire prevention and firefighting strategies, such as cooling with water to remove heat, removing fuel sources, or suffocating the fire by limiting oxygen access.
