1.
During a wet pipe sprinkler system installation, a pipe is found partially obstructed. What is the safest
corrective action?
A) Continue installation and monitor later
B) Remove obstruction and verify pipe clearance
C) Paint over the obstruction
D) Reduce water pressure
Answer: B) Remove obstruction and verify pipe clearance
Rationale: Obstructions block water flow, preventing proper coverage and compromising life safety.
2.

A dry pipe system trips frequently during winter. What is the most likely cause?
A) Cold ambient temperatures freezing the water in the pipe
B) Incorrect sprinkler spacing
C) Excessive pipe insulation
D) High water pressure
Answer: A) Cold ambient temperatures freezing the water in the pipe
Rationale: Dry systems rely on air pressure; freezing can trigger accidental activation.
3.
While testing a fire pump, the output pressure is below NFPA 20 requirements. Appropriate step?
A) Increase pipe diameter
B) Adjust pump settings or repair as needed
C) Reduce sprinkler demand
D) Ignore minor deviations
Answer: B) Adjust pump settings or repair as needed
Rationale: Fire pumps must meet minimum pressure to ensure adequate system performance during
emergencies.

4.
Why must control valves be locked and tagged after installation?
A) Optional for aesthetics
B) Prevent accidental closure and maintain system integrity
C) Reduce water flow
D) For recordkeeping only
Answer: B) Prevent accidental closure and maintain system integrity
Rationale: Locked and tagged valves ensure the system remains operational during emergencies.
5.
A foam-water system is installed in a flammable liquid storage area. Why is this system preferred?
A) Foam reduces fuel surface flammability and suppresses fire
B) Foam is decorative
C) Foam increases water flow
D) Foam prevents corrosion
Answer: A) Foam reduces fuel surface flammability and suppresses fire
