What does the "fire triangle" consist of?

The fire triangle consists of three essential components: fuel, heat, and oxygen. These elements are vital for a fire to ignite and continue burning.

Fuel is any combustible material that can burn, providing the necessary substance for combustion. Heat is the energy source that raises the temperature of the fuel to its ignition point, enabling it to catch fire. Oxygen, typically found in the air, is required for the chemical reaction known as combustion to occur, allowing the fire to sustain itself.

When any one of these components is removed or absent, the fire cannot start or will extinguish. This makes understanding the fire triangle crucial for firefighting efforts, as it helps firefighters to address and eliminate the factors contributing to a fire. For instance, when fighting a fire, one common strategy is to remove the heat by using water, which cools the fire and disrupts the combustion process.
