1. A pumper apparatus primary purpose is to:
A. Transport firefighters to incidents
B. Provide aerial access to upper floors
C. Supply and deliver water under pressure
D. Carry hazardous materials equipment
Rationale: A pumper is designed primarily for water supply and
fire suppression operations.
Answer: C
2. Which component creates the vacuum needed for drafting water?
A. Relief valve
, B. Primer pump
C. Governor
D. Intake strainer
Rationale: The primer removes air from the pump chamber to
create suction for drafting.
Answer: B
3. The purpose of a pump relief valve is to:
A. Increase pump speed
B. Prevent over-pressurization of discharge lines
C. Filter incoming water
D. Control engine RPM
Rationale: Relief valves protect hose and equipment from
excessive pressure.
Answer: B
4. What is the standard fireground hose discharge pressure for 1¾-
inch attack line?
A. 50 psi
B. 75 psi
C. 100 psi
, D. 150 psi
Rationale: 1¾-inch lines are commonly operated at 150 psi
nozzle pressure in many fire service standards.
Answer: D

Rationale: Check valves allow one-way flow only.
Answer: B
6. When drafting water, the maximum practical lift is approximately:
A. 5 feet
B. 10 feet
C. 14 feet
D. 25 feet
Rationale: Atmospheric pressure limits drafting lift to about 14
, feet.
Answer: C
7. Cavitation in a fire pump occurs when:
A. Water temperature drops
B. Air enters the pump causing pressure spikes
C. Vapor bubbles collapse due to low pressure
D. Pump speed is too low
Rationale: Cavitation is caused by vapor bubble collapse due to
low pressure conditions.
Answer: C
8. The device used to control engine RPM automatically is called:
A. Pressure governor
B. Intake valve
C. Priming pump
D. Booster tank
Rationale: Governors regulate engine speed to maintain
