What are the three components of the fire triangle?

The three components of the fire triangle are oxygen, heat, and fuel. Each of these elements is essential for a fire to ignite and sustain itself.

Oxygen is a critical component because it supports combustion. Without it, a fire cannot occur or be maintained. In most cases, the air around us contains sufficient oxygen (about 21%) to facilitate the burning process.

Heat is necessary to raise the material to its ignition temperature, allowing the chemical reactions of combustion to begin. This heat can come from various sources, such as friction, electrical sparks, or an open flame.

Fuel, which includes any material that can combust (like wood, paper, or gasoline), provides the energy source for the fire. When heat is applied to a fuel source in the presence of oxygen, the combustible reactions take place, creating the fire.

This understanding is fundamental for fire safety and management, as removing any one of these components can effectively extinguish a fire.
