The fire triangle consists of fuel, oxygen, and:
Answer: Heat
The fire triangle requires fuel, oxygen, and heat; removing any one extinguishes the fire.
A direct attack applies water:
Answer: Directly onto the burning fuel
A direct attack applies the stream straight onto the seat of the fire to cool the burning fuel.
Convection most commonly spreads fire in a building by:
Answer: Rising hot gases moving upward and through openings
Convection spreads fire as heated gases rise and travel through stairwells, halls, and openings to upper floors.
Which condition describes a fuel-controlled fire?
Answer: Burning is limited by available fuel
A fuel-controlled fire has ample oxygen, so its growth is limited only by the amount of available fuel.
Removing fuel from a fire to extinguish it is an example of:
Answer: Starvation
Starvation extinguishes fire by removing or isolating the fuel source.
Why should water generally NOT be used on a grease (Class K) fire?
Answer: It can cause the burning oil to splatter and spread violently
Water sinks into hot grease, vaporizes instantly, and ejects burning oil, dramatically spreading the fire.
The point at which a fire has consumed all available fuel and oxygen in a compartment and stops growing describes a fire that is:
Answer: Ventilation-limited
A ventilation-limited fire has consumed most oxygen, so its intensity is constrained by available air rather than fuel.
