1. When reviewing commercial fire sprinkler plans, the first step is
to:
A. Verify hydraulic calculations
B. Ensure code compliance with occupancy classification
C. Check pipe diameters
D. Approve contractor installation
B. Ensure code compliance with occupancy classification
Occupancy classification determines the type of sprinkler system
and design requirements; reviewing it first ensures the system is
appropriate for the building use.
2. NFPA 13 requires that the minimum sprinkler system design
density for light hazard occupancies is:
A. 0.10 gpm/ft²
B. 0.15 gpm/ft²
C. 0.20 gpm/ft²
D. 0.25 gpm/ft²
B. 0.15 gpm/ft²
, Light hazard occupancies like offices and schools have lower fuel
loads, thus the minimum design density is 0.15 gpm/ft².
3. Which symbol on a sprinkler plan indicates a standard upright
sprinkler head?
A. Circle with cross
B. Triangle
C. Square with dot
D. Diamond
A. Circle with cross
NFPA 13 standard symbols designate sprinkler types, and a circle
with a cross usually represents upright sprinklers.
4. The primary purpose of a hydraulic calculation in sprinkler design
is to:
A. Determine water supply size
B. Verify pipe length
C. Confirm adequate pressure and flow to all sprinklers
D. Approve installation methods
C. Confirm adequate pressure and flow to all sprinklers
Hydraulic calculations ensure that sprinklers will operate
effectively throughout the system.
5. Which occupancy hazard classification represents warehouses
storing wood and paper products?
A. Light hazard
B. Ordinary hazard Group 1
C. Ordinary hazard Group 2
D. Extra hazard
C. Ordinary hazard Group 2
, Warehouses with moderate combustibles like wood and paper fall
under OH2, which has higher density requirements than OH1.
6. On a sprinkler plan, what does the letter "FDC" stand for?
A. Fire Department Connection
B. Flow Direction Control
C. Fire Detection Center
D. Floor Drain Connection
A. Fire Department Connection
The FDC allows the fire department to supply water to the
sprinkler system in case of emergency.
7. The minimum distance between a sprinkler head and a
combustible ceiling is:
A. 1 inch
B. 3 inches
C. 6 inches
D. 12 inches
B. 3 inches
NFPA 13 specifies clearances to prevent heat shielding and ensure
proper sprinkler activation.
8. Dry pipe sprinkler systems are typically used in:
A. Offices
B. Warehouses in heated areas
C. Unheated or cold areas where freezing may occur
D. Light hazard occupancies
C. Unheated or cold areas where freezing may occur
Dry pipe systems prevent water from freezing in unheated areas
by keeping pipes filled with air until activation.
, 9. Which device is used to test water flow in a sprinkler system?
A. Check valve
B. Flow switch
C. Pressure gauge
D. Relief valve
B. Flow switch
Flow switches detect water movement when a sprinkler activates
and can signal alarms.
10. The most common standard coverage area for a single
sprinkler in light hazard occupancy is:
A. 100 ft²
B. 144 ft²
C. 225 ft²
D. 400 ft²
C. 225 ft²
NFPA 13 defines maximum coverage per sprinkler; for light hazard,
it is typically 225 ft².
11. The minimum design pressure at the most remote sprinkler
is:
A. 5 psi
B. 7 psi
C. 15 psi
D. 20 psi
B. 7 psi
NFPA 13 requires a minimum of 7 psi at the most remote sprinkler
to ensure proper operation.
