The Fire Triangle is composed of which three elements?

The Fire Triangle is composed of which three elements?

• A. Water, Oxygen, Heat
• B. Fire, Oxygen, Fuel
• C. Heat, Oxygen, Fuel
• D. Heat, Fuel, Water

Answer: (C)

Combustion needs three things: heat, oxygen, and fuel. Heat provides the energy to raise the material to its ignition temperature; without enough heat, fuel won’t ignite or will burn out. Oxygen supports the chemical reaction that keeps flames going; without sufficient oxygen, the fire cannot continue. Fuel is the combustible material that burns; remove it and the flame has nothing to burn. Because all three must be present for a fire to exist, removing any one of them stops the blaze. That’s why cooling with water (reduces heat), removing or isolating the fuel, or smothering to limit oxygen are effective firefighting tactics. The other options introduce element names that aren’t part of the triangle (such as water) and don’t represent the trio that sustains combustion.
