What are the four elements of the fire tetrahedron?

The four elements of the fire tetrahedron are correct as stated: oxygen, heat, fuel, and the chemical reaction itself. Understanding this concept is crucial as it forms the basis of fire science and firefighting practices.

Oxygen is essential because it supports combustion; without it, a fire cannot exist. Heat is the energy needed to raise the material to its ignition temperature, allowing the chemical reactions of combustion to occur. Fuel is the combustible material that provides the necessary elements for a fire to sustain itself. Lastly, the chemical reaction refers to the process of combustion, where fuel combines with oxygen in an exothermic reaction, producing heat and light.

Recognizing these four elements is essential for effective fire control and prevention strategies because removing any one of them will extinguish the fire. This foundational knowledge is vital for facility fire brigade members as they are often responsible for implementing safety protocols and responding to fire emergencies.
