FIRE APPARATUS DRIVER-OPERATOR EXAMINATION
COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
1.
Before leaving the station for an emergency response, which action by the
apparatus driver/operator is most important for identifying a potentially
dangerous mechanical deficiency?
A. Checking only the exterior warning lights
B. Performing the required visual and operational inspection
C. Waiting until arriving at the emergency scene
D. Starting the engine and immediately departing
Answer: B
Rationale: A complete visual and operational inspection helps identify
deficiencies involving critical systems before the apparatus is placed into
emergency service.
2.
While responding to a reported structure fire, the driver/operator approaches a
congested intersection with limited visibility and a changing traffic signal. What
should the operator do?
,A. Accelerate through the intersection because warning devices are activated
B. Maintain maximum speed regardless of surrounding traffic
C. Reduce speed and proceed only after confirming the intersection is reasonably
clear
D. Turn off warning devices to avoid confusing motorists
Answer: C
Rationale: Emergency warning devices do not eliminate traffic hazards. The
operator must continuously evaluate traffic and control the apparatus safely.
3.
A pumper arrives at a structure fire, and the engine officer requests immediate
water supply from a hydrant. What should the driver/operator consider first
when positioning the apparatus?
A. Parking as close to the building as physically possible
B. Maintaining safe access, hose deployment space, and appropriate operating
position
C. Blocking every available roadway regardless of emergency needs
D. Positioning directly beneath overhead electrical conductors
Answer: B
Rationale: Apparatus placement must support fireground operations while
maintaining safe access, working space, and awareness of surrounding hazards.
4.
,When operating a centrifugal fire pump, what condition generally allows the
pump to develop and maintain the desired discharge pressure?
A. A properly supplied pump with adequate water entering the intake
B. A completely closed intake valve
C. An empty apparatus water tank
D. A closed discharge outlet supplying attack lines
Answer: A
Rationale: Centrifugal pumps require an adequate water supply and appropriate
intake conditions to produce sustained discharge pressure.
5.
During a pump operation, the discharge pressure suddenly drops while the intake
pressure also decreases significantly. What should the driver/operator investigate
first?
A. Possible reduction or interruption of the water supply
B. Increasing engine speed without checking anything else
C. Closing all discharge valves immediately
D. Removing the pump primer from service
Answer: A
Rationale: A simultaneous reduction in intake and discharge pressure commonly
indicates a developing water-supply problem.
, 6.
A driver/operator must position a pumper near a roadway during nighttime
operations. Which practice provides the greatest protection for personnel
working around the apparatus?
A. Parking without considering traffic direction
B. Establishing an appropriately protected work area with warning devices
C. Turning off all apparatus lighting
D. Allowing personnel to work directly in traffic lanes
Answer: B
Rationale: Traffic-control measures and appropriate warning devices help
establish a protected operational area around emergency apparatus.
7.
When preparing to draft water from an open source, why is hard suction hose
particularly important?
A. It prevents the hose from collapsing under atmospheric pressure during
drafting
B. It automatically increases pump discharge pressure
C. It eliminates the need for pump priming
D. It replaces the need for a strainer
Answer: A
Rationale: Drafting creates negative pressure at the pump intake, making rigid or
appropriately supported suction hose necessary to resist collapse.
