Q1 QUESTION 1 OF 109
The lowest acceptable fuel gauge reading on a fire apparatus during inspection would be:
CORRECT ANSWER
A. At least ½-full
B. At least ⅔-full
C. At least ¾-full (Correct Answer)
D. Full
RATIONALE
Ensuring adequate fuel reserves, at least ¾-full, is critical for a fire apparatus to maintain
operational readiness for extended responses and unexpected demands. This reserve capacity
prevents premature fuel depletion during emergency operations.
Q2 QUESTION 2 OF 109
The purchase acceptance test on a new fire apparatus should focus on:
CORRECT ANSWER
A. Pump capacity
B. Road tests
C. Pump and foam operations
D. Bid specifications (Correct Answer)
RATIONALE
The purchase acceptance test must verify that the apparatus meets all the requirements outlined in
the bid specifications to ensure it conforms to the contractually agreed-upon capabilities and
features. This comprehensive validation prevents disputes and confirms the delivered equipment
fulfills the agency's specific needs.
Q3 QUESTION 3 OF 109
All of the following are rescue tools EXCEPT:
Page 2
, CORRECT ANSWER
A. Spreaders
B. Extensions rams
C. Drills (Correct Answer)
D. Shears
RATIONALE
Rescue tools are designed for rapid extrication, with spreaders, extension rams, and shears all
functioning as hydraulic or mechanical implements for breaching or manipulating structures,
whereas drills are primarily for creating holes and are not typically classified as primary extrication
devices. The key underlying concept is the categorization of emergency rescue equipment based
on its primary function in vehicle or structural extrication.
Q4 QUESTION 4 OF 109
On the vacuum service test, the system vacuum and pump priming device should achieve a
column of mercury of at least:
CORRECT ANSWER
A. 10 Inches
B. 11 Inches
C. 16 Inches
D. 22 Inches (Correct Answer)
RATIONALE
A vacuum service test verifies the pump's ability to create sufficient negative pressure for proper
operation, with 22 inches of mercury representing the minimum acceptable vacuum for effective
priming and system function. The key concept tested is the operational standard for vacuum pump
performance in a service environment.
Q5 QUESTION 5 OF 109
Determine the PDP for a siamesed layout in which there is an attack line of a 200-feet with a
1 ¼-inch solid stream nozzle operating at 45 psi. The friction loss from supply hoses is 30 psi.
The friction loss from the attack hose is 25 psi. In addition, there is an elevation gain of 40
feet between pump and nozzle. Total flow is 350 GPM.
Page 3
, CORRECT ANSWER
A. 85 psi
B. 105 psi
C. 130 psi (Correct Answer)
D. 155 psi
TFL = NP + EP + APL
TFL = (45+30+25) + 20 + 10
TFL = 130
RATIONALE
The total pump discharge pressure is calculated by summing the nozzle pressure, friction loss in the
supply and attack hoses, and the elevation pressure gain. This accounts for all pressure demands to
deliver the required flow at the nozzle.
Q6 QUESTION 6 OF 109
During service testing, it is important that the water temperature be between:
CORRECT ANSWER
A. 50°F and 100°F
B. 35°F and 90°F (Correct Answer)
C. 50°F and 100°F
D. 50°C and 100°C
RATIONALE
2°C) being the accepted range to ensure system integrity and prevent microbial growth. This range
balances the risk of pipe damage from freezing against the potential for thermal degradation of
materials or scalding.
Q7 QUESTION 7 OF 109
As salt water or water containing certain chemicals can corrode the apparatus pump, you
should:
