systems?
A. NFPA 10
B. NFPA 13
C. NFPA 72
D. NFPA 101
Answer: B. NFPA 13
Rationale: NFPA 13 provides the requirements for the design and installation of
automatic fire sprinkler systems, including placement, spacing, and water supply
criteria .
2. What is the primary purpose of a fire sprinkler system?
A. Smoke removal from a building
B. Fire suppression and control
C. Structural cooling only
,D. Electrical system shutdown
Answer: B. Fire suppression and control

automatically until firefighters arrive .
3. What is the minimum spacing allowed between sprinkler heads in a standard
light hazard occupancy?
A. 10 feet
B. 12 feet
C. 15 feet
D. 20 feet
Answer: C. 15 feet

4. What type of sprinkler system has pipes filled with water at all times?
A. Dry pipe system
B. Pre-action system
,C. Wet pipe system
D. Deluge system
Answer: C. Wet pipe system
Rationale: Wet pipe systems are constantly filled with water under pressure,

5. Which type of sprinkler system is designed for areas subject to freezing?
A. Wet pipe
B. Dry pipe
C. Deluge
D. Pre-action
Answer: B. Dry pipe

back by a valve until a sprinkler head activates, preventing freezing .
6. What is the minimum water pressure required at a sprinkler head for proper
operation per NFPA 13?
A. 5 psi
, B. 7 psi
C. 10 psi
D. 15 psi
Answer: B. 7 psi
Rationale: NFPA 13 specifies a minimum operating pressure of 7 psi at the
sprinkler to ensure proper discharge patterns and adequate coverage .
