What does a fire triangle consist of?

The fire triangle is a fundamental concept in fire science that describes the three essential elements needed to ignite and sustain a fire. These elements are fuel, oxygen, and heat.

Fuel refers to any combustible material that can ignite and burn, such as wood, paper, or gasoline. Oxygen is necessary for combustion to occur, as it reacts with the fuel at elevated temperatures. Heat is the energy needed to raise the material to its ignition temperature, enabling the combustion process to begin.

By understanding the fire triangle, it becomes clear that if one of these components is removed, the fire cannot continue to burn. This principle is crucial in fire prevention and safety measures, as it informs strategies to extinguish fires, such as depriving them of oxygen (smothering) or cooling them down (using water or extinguishing agents).

The other options include elements or combinations that do not accurately represent the essential components of combustion. For instance, carbon is a product of combustion rather than a necessary element for fire, and water is used to extinguish fires but does not constitute a part of the fire triangle.
