1. What is the minimum spacing requirement for ceiling-mounted
sprinkler heads in a standard light hazard occupancy?
a) 10 feet
b) 12 feet
c) 15 feet
d) 20 feet
b) 12 feet
Most light hazard occupancies require sprinklers to be spaced no
more than 12 feet apart to ensure adequate coverage.
2. What type of fire extinguisher is recommended for a Class B fire?
a) Water
b) Foam
c) Carbon dioxide
d) Wet chemical
c) Carbon dioxide
Class B fires involve flammable liquids; CO₂ extinguishers remove
oxygen and suppress flames without leaving residue.
3. NFPA 13 provides standards for the installation of what system?
a) Fire alarms
b) Sprinkler systems
, c) Smoke detectors
d) Fire doors
b) Sprinkler systems
NFPA 13 sets the minimum requirements for the design and
installation of automatic fire sprinkler systems.
4. Which type of sprinkler head activates at the lowest temperature?
a) Standard response
b) Quick response
c) Intermediate response
d) Deluge
b) Quick response
Quick response sprinklers are designed to activate faster, typically
in areas with high occupant density.
5. In a wet-pipe sprinkler system, water is:
a) Stored in a tank above the system
b) Continuously present in the piping
c) Released from a dry pipe valve
d) Held in a pressurized cylinder
b) Continuously present in the piping
Wet-pipe systems always have water in the pipes, providing
immediate discharge when a sprinkler activates.
6. The purpose of a fire department connection (FDC) is to:
a) Drain water from the system
b) Provide additional water supply to the sprinkler system
c) Monitor sprinkler activation
d) Connect fire alarms to the system
b) Provide additional water supply to the sprinkler system
, FDCs allow firefighters to supplement the building’s water supply
in emergencies.
7. What is the maximum allowable distance between sprinkler heads
in a standard light hazard occupancy?
a) 8 feet
b) 12 feet
c) 15 feet
d) 18 feet
b) 12 feet
This spacing ensures complete coverage without gaps in
protection.
8. The primary function of a fire suppression system is to:
a) Alert occupants
b) Suppress or control fire
c) Detect smoke
d) Ventilate smoke
b) Suppress or control fire
Fire suppression systems actively control or extinguish fire to
minimize damage and risk.
9. In a dry-pipe sprinkler system, water is:
a) Always present in the piping
b) Released immediately upon activation
c) Held back by a dry pipe valve until needed
d) Stored in a pressurized tank
c) Held back by a dry pipe valve until needed
Dry-pipe systems keep water out of the pipes to prevent freezing;
the valve releases water when a sprinkler opens.
, 10. What is the maximum water pressure allowed at a sprinkler
head?
a) 100 psi
b) 175 psi
c) 200 psi
d) 250 psi
b) 175 psi
Sprinkler heads are rated for a maximum operating pressure,
typically 175 psi, to prevent damage.
11. A deluge sprinkler system is primarily used for:
a) Light hazard occupancies
b) High-hazard areas
c) Residential buildings
d) Offices and retail
b) High-hazard areas
Deluge systems release large volumes of water quickly in areas
with rapid fire spread risk.
12. The main difference between a wet-pipe and dry-pipe
sprinkler system is:
a) The type of sprinklers used
b) The water supply method
c) The activation temperature
d) The piping material
b) The water supply method
Wet-pipe systems always have water in the pipes, whereas dry-
pipe systems keep pipes empty until activation.
