What does the basic fire triangle consist of?

The basic fire triangle consists of heat, fuel, and oxygen. This model illustrates the three essential elements that must be present for a fire to ignite and sustain combustion.

Heat provides the necessary energy to raise the material to its ignition temperature. Fuel refers to any combustible material that can burn, such as wood, paper, or gasoline. Oxygen, typically from the air, supports the combustion process by reacting with the fuel.

Understanding the fire triangle is critical for fire prevention and control. By removing any one of the elements—heat, fuel, or oxygen—fire can be extinguished. This foundational concept informs many fire safety protocols and firefighting strategies, highlighting its importance in both education and practical applications in fire safety.
