Assuming the conditions are satisfied for design area reduction, what can the area of sprinkler operation be reduced to for quick response sprinklers?

An office space with 10 ft (3 m) high ceilings is designated as a Light Hazard Occupancy. It is determined that the area of sprinkler operation is 1,500 ft2 (139 m2).

Assuming the conditions are satisfied for design area reduction, what can the area of sprinkler operation be reduced to for quick response sprinklers?
A . 800 ft2 (74 m2)
B . 900 ft2 (84 m2)
C . 1,100 ft2 (102 m2)
D . 1,200 ft2 (111 m2)

Answer: C

Explanation:

NFPA 13 allows for a reduction in the design area for quick-response sprinklers under certain conditions, such as in light hazard occupancies with ceilings not exceeding 12 ft in height. A reduction to 1,100 ft² is consistent with the allowance for using quick-response sprinklers to cover a smaller area more effectively due to their faster activation in fire scenarios.
