Which term matches the definition: A three dimensional representation of requirements for fire to occur: fuel, heat, and oxygen?

• A. Hygiene
• B. PFD
• C. Glucose
• D. Fire Triangle

Answer: (D)

Fire occurs when heat, fuel, and oxygen come together. The Fire Triangle is the simple model that shows these three elements as the corners of a triangle, illustrating that all three are needed for a fire to start and continue. If any one element is removed—cool the heat, remove the fuel, or reduce the oxygen—the fire cannot sustain itself. That’s why this term fits the definition best. The other options don’t relate to what fires need to ignite: hygiene is about cleanliness, PFD is a personal flotation device, and glucose is a sugar used for energy.
