What are the three sides of the fire triangle?

The three sides of the fire triangle are essential components required for a fire to ignite and sustain combustion. They include heat, fuel, and oxygen. Heat is necessary to raise the material to its ignition temperature. Fuel provides the substance that burns, which could be anything from wood to gasoline. Oxygen is a key element needed for combustion; without it, fires cannot sustain themselves.

Understanding the fire triangle is crucial for fire prevention and control strategies. For example, if you eliminate any one of these components, you can extinguish a fire.

The other options do not accurately represent the components of the fire triangle. Water is not a component of the fire triangle; rather, it is often used as an extinguishing agent. Smoke is a byproduct of combustion and does not contribute to the fire itself. Therefore, these alternatives do not encompass the necessary elements for a fire to exist.
