Which of the following statements is NOT a component of the fire triangle?

• A. Water
• B. Fire
• C. Oxygen
• D. Source of Ignition

Answer: (A)

The fire triangle shows three elements that must be present for a fire to occur: heat to raise fuel to its ignition temperature, fuel to feed the flames, and oxygen to sustain the chemical reaction. Water is not one of these elements. Instead, it acts to cool the fire, absorbing heat and lowering the temperature so the reaction can no longer continue. That’s why water is used to extinguish fires—but it’s not a basic component of what keeps a fire burning. The other concepts listed (the fire itself and a source of ignition) describe what starts or results from the process, not the three sustaining elements.
