What are the three components of the fire triangle?

The three components of the fire triangle are oxygen, heat, and fuel. This concept is fundamental in understanding how fire starts and is sustained.

Oxygen is essential for combustion; it reacts with fuel when heat is applied, creating a chemical reaction that produces fire. Without oxygen, a fire cannot burn, which is why removing oxygen is a common method used in fire suppression efforts.

Heat is the energy source that raises the temperature of the fuel to its ignition point, causing it to combust. It can come from various sources, such as electrical sparks, open flames, or friction.

Fuel refers to any material that can combust, such as wood, gasoline, or paper. All three components — oxygen, heat, and fuel — must be present for a fire to ignite and continue burning. If any one of these elements is removed, the fire will extinguish. This foundational principle is crucial for firefighters and anyone involved in fire safety and prevention.
