What are the three components of the triangle of fire?

• A. Water, Fuel, Pressure
• B. Fuel, Heat and Oxygen
• C. Oxygen, Pressure and Vapor
• D. Heat, Smoke and Dust

Answer: (B)

Fires need three elements to start and keep burning: heat, fuel, and oxygen. If you remove one of these, the fire can’t sustain itself. That’s why the correct answer is fuel, heat and oxygen. In practice, you can stop a fire by cooling it with water (removing heat), removing or isolating the fuel source (like shutting off a gas supply or clearing flammable materials), or smothering the fire to cut off the oxygen supply (for example, using a fire blanket or a lid). Other listed factors such as water, pressure, vapor, smoke, or dust aren’t the fundamental components that keep a fire going, so they don’t describe what the triangle of fire is about.
