If you remove one of the elements of the fire triangle, will it extinguish the fire?

• A. Yes
• B. No
• C. Only with water
• D. Not always

Answer: (A)

Fire needs three ingredients: heat, fuel, and oxygen. Remove any one of them and the combustion can’t be sustained. Cooling with water removes heat below the ignition temperature. Removing the fuel source stops new fuel from feeding the flame. Smothering or limiting air cuts the oxygen supply so the flame can’t continue. Because extinguishing can be achieved by taking away one element, the fire will be put out. While there are different ways to apply these ideas in practice, the basic idea remains that eliminating a single essential ingredient stops the fire.
