Ordinary hazard areas are allowed sprinklers under what condition?

• A. Sprinklers prohibited in ordinary hazard areas.
• B. Sprinklers must be wet-type in ordinary hazard areas.
• C. Sprinklers permitted under specific compartment conditions.
• D. Sprinklers must be installed in every room.

Answer: (C)

Sprinklers can be used in ordinary hazard areas as long as those areas are properly subdivided into compartments by fire barriers. This compartmenting keeps the area protected by a single sprinkler system within size and hydraulics limits, so the fire loading and water demands stay manageable. The idea is that ordinary hazard sprinklers aren’t allowed to blanket a large open space; they’re permitted when the space is divided into defined compartments that meet the design requirements, and each compartment is designed with the appropriate sprinkler coverage. That’s why the best answer is that sprinklers are allowed under specific compartment conditions. It isn’t a blanket prohibition, and it doesn’t require a particular sprinkler type or that every room must have a sprinkler.
