A fire will be extinguished when which component is eliminated?

A fire is fundamentally a chemical reaction involving the three elements known as the fire triangle: fuel, heat, and oxygen. To extinguish a fire, it is crucial to eliminate at least one of these components.

When fuel is removed, there’s nothing left for the fire to consume, effectively starving it and causing it to go out. If heat is eliminated—such as by dousing with water or using a fire extinguisher—the temperature drops below the material’s ignition point, halting combustion. Similarly, if the supply of oxygen is cut off, the fire cannot continue to burn since oxygen is necessary for combustion.

Thus, eliminating any one of these components—fuel, heat, or oxygen—will extinguish the fire. The option indicating that each of these components must be eliminated indeed underscores the comprehensive understanding of fire dynamics, making "each of the above" the correct answer.
