Question 1

During a department's hydrant-supplied pump-performance check, a pumper delivers 1,500 gpm with 225 psi at the discharge and positive 60 psi at the intake. Both readings come from calibrated instruments; elevation and velocity corrections are negligible. The department requires at least 150 psi net pump pressure at this flow, and all other test conditions have been satisfied. Which entry correctly records the pressure result?

Accepted Answer

165 psi net; the pressure criterion is met.

Answer

225 psi net; the pressure criterion is met.

Answer

285 psi net; the pressure criterion is met.

Answer

Net pressure cannot be established without repeating the test from draft.

Question 2

A control module is used only on the department's sole aerial apparatus. One has failed in two years, but failure disables aerial operation. Replacements take six weeks to arrive, no compatible substitute is available, and a spare can be stored for the apparatus's remaining service life without deterioration. What stocking policy best balances readiness and inventory cost?

Accepted Answer

Hold one serviceable spare and periodically review demand and lead time.

Answer

Order a replacement only after a failure because annual usage is low.

Answer

Buy several replacements now to cover all projected failures before the apparatus is retired.

Answer

Use vendor-managed replenishment without requiring guaranteed stock or a delivery commitment.

Question 3

Several unopened containers of the fleet's specified automotive diesel exhaust fluid (DEF) freeze during an overnight cold spell. The containers remain intact, the fluid is within its shelf life, and there is no contamination. After the contents have completely thawed, how should the stock be handled?

Accepted Answer

Use the fluid without dilution or freeze-prevention additives.

Answer

Replace the stock because freezing permanently changes the urea concentration.

Answer

Add deionized water to restore the concentration lost during freezing.

Answer

Add a diesel anti-gel product to protect the fluid during its next cold exposure.

Question 4

Supervisor A assigns an approved water-tank repair to an EVT II technician qualified for the tank material and repair procedure. Supervisor B assigns recurring-failure analysis and evaluation of repair-time estimates to an EVT III technician. Whose assignment is consistent with the technician-level responsibilities addressed by NFPA 1910 (2024)?

Accepted Answer

Both supervisors

Answer

Supervisor A only

Answer

Supervisor B only

Answer

Neither supervisor

Question 5

Two municipal shops maintain comparable pumpers with similar duty cycles. East reports a lower total maintenance cost per mile, but its calculation excludes outside repair invoices. West includes those invoices along with parts and technician labor. Before East is adopted as the cost benchmark, the supervisor needs to:

Accepted Answer

Include outside repairs in both shops' total-maintenance-cost calculations.

Answer

Compare annual maintenance totals instead of dividing either total by miles.

Answer

Use cost per completed work order to compensate for the different expense categories.

Answer

Compare in-house labor alone and treat that result as total maintenance performance.

Question 6

An ambulance has a 16,000-lb gross vehicle weight rating (GVWR), a 6,500-lb front gross axle weight rating (GAWR), and a 9,800-lb rear GAWR. In its fully loaded service configuration, it weighs 5,000 lb at the front and 9,400 lb at the rear. A proposed 600-lb equipment installation would reduce the front load by 100 lb and increase the rear load by 700 lb, as verified by the manufacturer's loading analysis. Wheel and tire ratings are not more restrictive. Which decision correctly evaluates the new loading?

Accepted Answer

Revise the installation; the rear axle would exceed its GAWR by 300 lb.

Answer

Approve; the combined axle ratings exceed the new total vehicle weight.

Answer

Approve; 1,000 lb of capacity remains under the vehicle's GVWR.

Answer

Revise the installation; the rear axle would exceed its GAWR by 200 lb.

Question 7

An employer covered by the Americans with Disabilities Act is interviewing applicants for a fleet-technician position. No conditional job offer has been made. The supervisor has described the essential brake-service tasks and the lifting equipment provided. Which follow-up question is permissible at this stage?

Accepted Answer

Can you perform these tasks, with or without reasonable accommodation?

Answer

What back injuries have required medical treatment during your previous employment?

Answer

Which prescribed medications could affect your ability to work around moving apparatus?

Answer

Did a physician ever place you on medical restrictions in a previous job?

Question 8

Using calibrated instruments, a technician verifies a pumper's rated output while drafting from an external source. When supplied instead from a full onboard tank, the pump fails its specified tank-to-pump flow requirement through the same discharge outlet. Engine speed and the discharge setup are unchanged. Where should the initial inspection focus?

Accepted Answer

The tank vent, outlet, tank-to-pump valve, and connecting piping

Answer

The discharge-pressure governor and its pressure-sensing connection

Answer

The main pump impeller and the clearances at its wear rings

Answer

The primer and the suction-hose connections used for external drafting

Question 9

A reserve pumper needs a $28,000 repair to provide three more years of service. Keeping it would cost $12,000 per year to operate and maintain, with a $10,000 sale value at the end. A mission-equivalent replacement is available now for $140,000, would cost $6,000 per year to operate and maintain, and could be sold for $70,000 after three years. The old pumper can be sold unrepaired today for $20,000; it also received an $18,000 repair last year. Both choices meet safety and availability needs. Using undiscounted future cash flows, which choice has the lower three-year net cost?

Accepted Answer

Keep the pumper; keeping it costs $14,000 less.

Answer

Replace the pumper; replacement costs $4,000 less.

Answer

Keep the pumper; keeping it costs $34,000 less.

Answer

Keep the pumper; keeping it costs $74,000 less.

Question 10

A structural pumper is contracted to NFPA 1900 (2024). The signed purchase specification also explicitly requires a vehicle data recorder (VDR). During pre-delivery review, the manufacturer proposes omitting the recorder, citing the 2024 standard's treatment of VDRs. What governs resolution of this omission?

Accepted Answer

The contract still requires the recorder, even though NFPA now addresses it in annex guidance.

Answer

The omission violates NFPA 1900 because the standard still mandates a recorder on every structural pumper.

Answer

The omission is acceptable because an annex recommendation cannot become a mandatory requirement in a purchase contract.

Answer

The recorder may be omitted if the engine-control module already stores diagnostic trouble codes for maintenance review.
