Which trio makes up the Fire Triangle?

Which trio makes up the Fire Triangle?

• A. Water, carbon dioxide, heat
• B. Fuel, water, heat
• C. Oxygen, heat, water
• D. Fuel, Oxygen, Heat

Answer: (D)

Fire can keep burning only when three things are present: fuel, oxygen, and heat. Fuel is any material that can burn, like wood, gasoline, or paper. Oxygen comes from the air and enables the chemical reaction that we call combustion. Heat is the energy that raises the fuel to its ignition temperature and keeps the reaction going. If you remove any one of these elements, the fire can’t sustain itself. Cooling with water lowers the heat, removing fuel stops the supply, and shielding or starving the flame reduces the oxygen. Water is used to remove heat, not because it’s part of the triangle, so the essential trio remains fuel, oxygen, and heat.
