What are the three components collectively known as the "Fire Triangle"?

• A. Oxygen, fuel, and LEL
• B. Fuel, fire, and carbon dioxide
• C. Fuel, oxygen, and ignition source
• D. Ignition source, carbon dioxide, and fuel

Answer: (C)

The three components collectively known as the "Fire Triangle" are fuel, oxygen, and an ignition source. This concept is fundamental in understanding how fires start and are sustained.

Fuel refers to any combustible material that can burn, such as wood, paper, gasoline, or other flammable substances. Oxygen is essential for combustion, as it supports the chemical reaction that occurs when a fire ignites. The ignition source is the trigger that starts the fire, which can be anything from a spark, flame, heat source, or electrical discharge.

Without any one of these three components, a fire cannot ignite or continue to burn. Understanding the Fire Triangle helps in fire prevention, as removing any one component can effectively extinguish an existing fire or prevent it from starting in the first place.

The other options include components that may relate to fire and its behavior under certain conditions, but they do not accurately represent the fundamental elements of the Fire Triangle. For instance, lower explosive limits (LEL) and carbon dioxide are related to fire safety and explosion risks but do not form the basic structure of how a fire begins.
