,  B) Rescue victims

 C) Property conservation

 D) Ventilate the structure

 Correct Answer: C) Property conservation Salvage operations focus on protecting property
from water, smoke, and fire damage by covering contents and removing items from danger.

 A) Incipient phase

 B) Growth phase

 C) Fully developed phase

 D) Decay phase

 Correct Answer: C) Fully developed phase During the fully developed phase, the fire has
consumed all available fuel in the compartment and is at its maximum heat release rate.



6. What acronym helps firefighters remember the steps in operating an extinguisher?

 A) PASS

 B) PULL

 C) PUSH

 A) Single-donut roll

 B) Twin-donut roll

 C) Straight roll

 D) Figure-eight roll

 A) Minutes before SCBA failure

,  B) Seconds for second-degree burn

 C) Minutes of usable air supply

 D) Seconds before flashover occurs

 Correct Answer: B) Seconds for second-degree burn The TPP (Thermal Protective
