1. What is the primary purpose of an automatic fire sprinkler
system?
A. To provide ventilation
B. To extinguish all fires immediately
C. To control or suppress a fire and limit its spread
D. To replace fire department response
Rationale: Automatic sprinkler systems are designed to control or
suppress fires during their early stages, reducing property damage
and increasing occupant safety until emergency responders arrive.
2. Which organization publishes the standard for the installation of
sprinkler systems?
A. OSHA
B. EPA
,C. ICC
D. NFPA
Rationale: NFPA 13, published by the National Fire Protection
Association (NFPA), establishes requirements for the design and
installation of automatic sprinkler systems.
3. What is the minimum residual pressure generally required at the
most remote sprinkler head in a light-hazard occupancy?
A. 3 psi
B. 5 psi
C. 7 psi
D. 15 psi
Rationale: NFPA 13 requires sufficient pressure and flow to meet the
design criteria. Many light-hazard sprinkler calculations result in
approximately 7 psi or more at the most remote sprinkler.
4. Which type of sprinkler system contains water in the piping at all
times?
A. Deluge system
B. Preaction system
C. Dry-pipe system
D. Wet-pipe system
,Rationale: Wet-pipe systems are the most common sprinkler systems
and maintain water-filled piping ready for immediate discharge when
a sprinkler activates.
5. What is the primary purpose of a fire department connection
(FDC)?
A. Drain the system
B. Test alarms
C. Allow firefighters to supplement water supply to the system
D. Monitor pressure
Rationale: An FDC allows the fire department to pump water into the
sprinkler or standpipe system during emergencies.
6. Which occupancy classification generally presents the lowest fire
risk?
A. Extra Hazard Group 2
B. Ordinary Hazard Group 2
C. Ordinary Hazard Group 1
D. Light Hazard
Rationale: Light-hazard occupancies, such as offices and churches,
contain relatively low quantities of combustible materials.
7. What activates a standard automatic sprinkler head?
, A. Smoke detection
B. Heat from a fire
C. Manual switch
D. Fire alarm signal
B. Heat from a fire
Rationale: Individual sprinkler heads activate when heat causes the
thermal element, such as a fusible link or glass bulb, to operate.
8. In a dry-pipe system, the piping is filled with:
A. Water
B. Foam solution
C. Nitrogen only
D. Pressurized air or nitrogen
Rationale: Dry-pipe systems use pressurized air or nitrogen to keep the
dry-pipe valve closed until sprinkler activation occurs.
9. What is the primary advantage of a dry-pipe system?
A. Lower installation cost
B. Better aesthetics
C. Reduced risk of freezing in cold environments
D. Increased pressure
