1. 1A sprinkler fitter must work near an unguarded roof edge. The selected system is adjusted so its fully extended connection prevents the worker from reaching any fall hazard. What type of fall protection system is being used?

   1. A.A travel restraint systemCorrect answer: A
   2. B.A fall arrest system
   3. C.A work positioning system
   4. D.A rope access system

   Explanation: CCOHS advises: "Adjust the system so that the connection between the worker and the anchor when fully extended prevents the worker from reaching any point where the worker may fall." This describes travel restraint, whose purpose is to prevent access to the fall hazard.

2. 2A fire-pump installation includes a small auxiliary pump that maintains sprinkler-system pressure while the main fire pump is on standby. What is this auxiliary pump called?

   1. A.A transfer pump
   2. B.A booster pump
   3. C.A jockey pumpCorrect answer: C
   4. D.A circulation pump

   Explanation: The New York City Department of Buildings defines a jockey pump as "A small pump connected to the sprinkler system used in conjunction with a fire pump to maintain system pressure." In the described arrangement, the auxiliary pressure-maintenance pump is the jockey pump.

3. 3A fitter prepares a sprinkler pipe end by cold-forming a circumferential groove without removing pipe material. Which preparation method is being used?

   1. A.Roll groovingCorrect answer: A
   2. B.Cut grooving
   3. C.Pipe threading
   4. D.Pipe reaming

   Explanation: Victaulic states that "a pipe is cold formed" when performing a roll groove, "creating a groove without removing any pipe material." Cut grooving removes material; threading and reaming are different pipe-preparation operations.

4. 4A sprinkler installation has pressurized air in its piping and no supplemental automatic detection system. Opening a sprinkler releases air, which trips the water supply valve. Which system arrangement is installed?

   1. A.Non-interlock preaction system
   2. B.Automatic dry-pipe sprinkler systemCorrect answer: B
   3. C.Single-interlock preaction system
   4. D.Double-interlock preaction system

   Explanation: The Canadian Conservation Institute says that in the dry system, "air is released from the pipe, opening the valve and releasing water into the pipes and out of the sprinkler." The preaction design guide defines a preaction system as having "a supplemental detection system installed in the same areas as the sprinklers." The absence of that detection system distinguishes the described dry-pipe arrangement, even from non-interlock preaction.

5. 5An existing dry-pipe system has operated with compressed air and is being converted to nitrogen without replacing all the existing piping. For hydraulic calculations associated with the modification, which Hazen–Williams C-factor does the cited NFPA committee discussion consider appropriate for the existing system?

   1. A.100Correct answer: A
   2. B.120
   3. C.140
   4. D.150

   Explanation: The NFPA committee explains that "Existing systems installed with compressed air can experience corrosion damage and a c-factor of 100 would be appropriate." Nitrogen can reduce further corrosion but does not repair corrosion already present, so the discussion does not apply the new-system value automatically.

6. 6A fitter leaves the required clearance behind the hook jaw when adjusting a pipe wrench around a steel pipe. Which surfaces provide the gripping contact as turning force is applied?

   1. A.The heel-jaw face and hook-jaw teethCorrect answer: A
   2. B.The heel-jaw face and hook-jaw shank
   3. C.The heel-jaw back and hook-jaw teeth
   4. D.The heel-jaw back and hook-jaw shank

   Explanation: The BC Industry Training Authority explains: "This permits the pressure of the two gripping surfaces (the heel jaw and the teeth of the hook jaw) to firmly grip the pipe for full turning force." The clearance prevents the hook-jaw shank from becoming a gripping surface.

7. 7A fitter checks the static pressure contributed by an elevated fire-protection water tank. The water surface is 20 feet above the connection, and friction losses are excluded. Using 0.433 psi per foot of elevation, what pressure does the elevation contribute at the connection?

   1. A.0.866 psi
   2. B.8.66 psiCorrect answer: B
   3. C.46.19 psi
   4. D.86.6 psi

   Explanation: NFPA states: "Water pressure increases by 0.433 psi for every foot of elevation gain". The elevation contributes 20 ft × 0.433 psi/ft = 8.66 psi. The other values result from using a tenfold smaller factor, dividing by 0.433, or using a tenfold larger factor, respectively.

8. 8After cutting a sprinkler pipe, a fitter needs to remove the burr at the end to promote hydraulic efficiency. Which pipe-preparation operation addresses that condition?

   1. A.Grooving the pipe end
   2. B.Reaming the pipe endCorrect answer: B
   3. C.Threading the pipe end
   4. D.Flaring the pipe end

   Explanation: The Red Seal standard states that "pipe is reamed according to industry practice to remove burrs to promote hydraulic efficiency". Reaming addresses the burr left by cutting; the other operations prepare the end for different joining purposes.

9. 9A fitter needs to monitor whether a normally open sprinkler control valve has been moved from its normal position. Which initiating device should be selected for that condition?

   1. A.A valve tamper switchCorrect answer: A
   2. B.A low-air pressure switch
   3. C.A paddle waterflow switch
   4. D.A low-water pressure switch

   Explanation: Nevada fire-protection training says that for control valves, "they can have a tamper switch that will operate if the valve position changes." This switch monitors the valve position; the other devices respond to flow or pressure.

   Reference: Nevada Fire Protection Systems Training — Fire Protection Systems, page SM PS-13

10. 10A fitter compares a stabilized main-drain reading with an original full-flow pressure of 80 psi. Under the cited NFPA 25 criterion, what current reading represents a 10% reduction from the original?

    1. A.8 psi
    2. B.70 psi
    3. C.72 psiCorrect answer: C
    4. D.88 psi

    Explanation: The maintenance manual states: "When there is a 10 percent reduction in full flow pressure when compared to the original acceptance test or previously performed tests, the cause of the reduction shall be identified and corrected if necessary." Ten percent of 80 psi is 8 psi, so the resulting reading is 80 − 8 = 72 psi. The other answers report the drop itself, subtract 10 psi rather than 10%, or add the 8 psi instead.
