1.
When performing a daily apparatus inspection, the operator should first check:
A. Fuel level
B. Pump packing
C. Tire pressure and condition
D. SCBA cylinders
Answer: C. Tires are critical for safe apparatus movement; checking pressure and condition
ensures safe response and prevents blowouts.
2.
The primary purpose of a centrifugal fire pump is to:
A. Create positive displacement
B. Increase water pressure by velocity conversion
C. Store water
D. Prime hose lines
Answer: B. Centrifugal pumps increase pressure by converting velocity energy into pressure
energy.
3.
When calculating friction loss in 1¾-inch hose, the formula used is:
A. FL = C × Q² × L
B. FL = NP – AP
C. FL = Q ÷ GPM
D. FL = PSI × 2
Answer: A. The friction loss formula is FL = C × Q² × L, where C is coefficient, Q is flow in
hundreds of GPM, and L is hose length in hundreds of feet.
4.
A safe following distance for emergency apparatus under normal conditions is:
,A. 1 second per 10 mph
B. 2 seconds total
C. 3 seconds per 10 feet
D. 1 apparatus length
Answer: A. Standard guidance is one second for every 10 mph of speed for large emergency
vehicles.
5.
The minimum recommended residual pressure while pumping is:
A. 10 psi
B. 15 psi
C. 20 psi
D. 25 psi
Answer: C. Maintaining at least 20 psi residual prevents pump cavitation and system damage.
6.
Cavitation occurs when:
A. Water freezes in the pump
B. Air enters discharge lines
C. Pressure exceeds 300 psi
D. Pump intake pressure drops too low
Answer: D. Cavitation happens when intake pressure is insufficient, causing vapor bubbles that
damage the pump.
7.
The most common type of fire apparatus transmission is:
A. Manual
B. Automatic
C. Dual clutch
D. Hydraulic direct
Answer: B. Modern fire apparatus typically use automatic transmissions for ease and safety.
8.
When positioning at a vehicle fire on a highway, apparatus should be angled:
,A. Toward traffic
B. Parallel to traffic
C. Away from traffic
D. At 90 degrees
Answer: C. Angling away protects firefighters from oncoming traffic and provides a safety
barrier.
9.
The pump operator should engage the pump:
A. While moving slowly
B. After coming to a complete stop
C. At high idle
D. With tank full only
Answer: B. The apparatus must be fully stopped before engaging the pump to prevent
mechanical damage.
10.
The purpose of a relief valve is to:
A. Increase pressure
B. Prime the pump
C. Remove air
D. Prevent excessive discharge pressure
Answer: D. Relief valves protect hose lines and personnel from dangerous pressure surges.
11.
Net pump pressure (NPP) is calculated by:
A. Discharge minus intake pressure
B. Intake minus discharge pressure
C. Adding intake and discharge
D. Dividing discharge by intake
Answer: A. NPP equals discharge pressure minus intake pressure.
12.
The maximum recommended speed for most fire apparatus on wet roads is reduced by:
, A. 5%
B. 10%
C. 25%
D. 50%
Answer: B. Standard defensive driving guidance suggests reducing speed by approximately 10%
on wet surfaces.
13.
When drafting, atmospheric pressure can lift water approximately:
A. 10 feet
B. 20 feet
C. 24 feet
D. 33.9 feet
Answer: D. Atmospheric pressure can theoretically lift water 33.9 feet at sea level.
14.
The coefficient for 2½-inch hose in friction loss calculation is typically:
A. 2
B. 8
C. 0.8
D. 15.5
Answer: C. The common coefficient used for 2½-inch hose is 0.8.
15.
The most effective way to prevent apparatus rollover is:
A. Rapid acceleration
B. Hard braking
C. Avoiding sudden steering inputs
D. Using siren continuously
Answer: C. Sudden steering inputs increase rollover risk in high-center-of-gravity vehicles.
16.
A master stream device flowing 500 GPM requires a minimum nozzle pressure of:
