What are the three components of the fire triangle?

• A. Heat, Oxygen and Fuel
• B. Energy, Pressure and Volume
• C. Spark, Smoke and Flame
• D. Fuel, Water and Air

Answer: (A)

The fire triangle shows that combustion needs three elements: heat to bring the material to its ignition temperature, fuel to feed the flame, and oxygen to sustain the chemical reaction. If any one of these is removed or reduced, the fire cannot continue. Heat can be cooled away with water to drop below ignition temperature, fuel can be cut off by removing or isolating combustibles, and oxygen can be limited by smothering or separating the fire from air. The other ideas listed mix concepts like energy, pressure, or include water, but they aren’t the three elements that must be present for a fire to start and keep burning.
