What is the maximum coverage area for a standard spray upright
sprinkler in Light Hazard occupancy?
A. 130 ft²
B. 196 ft²
C. 225 ft²
D. 256 ft²
Standard spray sprinklers in Light Hazard occupancies are typically
limited to 225 ft² per sprinkler.
,Question 3
Which type of pipe schedule system is most commonly used in modern
sprinkler design?
A. Tree system
B. Loop system
C. Gridded system

What is the minimum residual pressure required at the hydraulically
most remote sprinkler?
A. 5 psi
B. 7 psi
C. 10 psi
D. 15 psi
NFPA 13 requires a minimum of 7 psi at the most remote sprinkler to
ensure proper discharge.

proper spray distribution.
Question 7
Which hazard classification would a machine shop typically fall under?
A. Light Hazard
B. Ordinary Hazard Group 2
C. Extra Hazard Group 1
D. Storage Hazard
Machine shops typically involve moderate fire loads and are classified
as Ordinary Hazard Group 2.
, Question 8
What is the purpose of a hydraulic calculation in sprinkler system
design?
A. Determine pipe color
B. Select sprinkler type
C. Ensure adequate water supply and pressure
D. Determine ceiling height
Hydraulic calculations verify that the system can deliver the required
flow and pressure.
Question 9
What is the minimum size for a main drain valve?
A. 1 inch
B. 1½ inches
C. 2 inches
D. 2½ inches
NFPA 13 typically requires a minimum 2-inch main drain to allow proper
system drainage and testing.
Question 10
