Which elements make up the fire triangle?

• A. Smoke, Ignition, and Oxygen.
• B. Water, Fuel, and Heat.
• C. Heat, Fuel, and Oxygen.
• D. Wind, Fuel, and Temperature.

Answer: (C)

Fire needs three elements to keep burning: heat, fuel, and oxygen. Heat provides the energy to sustain the chemical reaction, fuel is what is burning, and oxygen supports the oxidation process. If any one of these is removed, the fire cannot continue. Cooling removes heat, removing the fuel source starves the flame, and reducing the amount of oxygen slows or stops the combustion. The other options mix elements that aren’t the fundamental sustainers of a fire—water is a cooling method, ignition is just the trigger to start burning, and wind or temperature influence flame behavior but aren’t the essential trio.
