Which concept explains that fire requires fuel, heat, and oxygen?

• A. Concussion
• B. Risk Factor
• C. Fire Triangle
• D. UV Rays

Answer: (C)

The main concept here is that a fire needs three elements to keep burning: heat to start and sustain the reaction, fuel to burn, and an oxidizer (oxygen) in the surrounding air. This idea is known as the Fire Triangle. In safety thinking, understanding this teaches how to prevent or stop fires by removing one of those elements. If you cool the fire, you remove heat; if you eliminate the fuel source, you starve the fire of fuel; if you restrict oxygen, you smother the flames. The other terms don’t describe what fuels a fire or the conditions needed for combustion. Concussion relates to a head injury, risk factor is about the chance of something happening but not the combustion process, and UV rays are unrelated to how fires burn.
