For a room or office classified as a light hazard, NFPA 13 limits the spacing for standard spray or upright pendant sprinklers to ____________.

• A. A. 3.7 feet
• B. B. 8 feet
• C. C. 12 feet
• D. D. 15 feet

Answer: (D)

In the context of NFPA 13, a light hazard classification applies to spaces where the materials and contents present a lower risk of fire. For standard spray or upright pendant sprinklers, the maximum allowable spacing is set to 15 feet in such environments. This guideline ensures efficient coverage and protection against potential fire hazards, allowing the sprinklers to effectively control or suppress fires while considering the reduced risk associated with light hazard areas. The spacing requirement is crucial for maintaining optimal sprinkler performance and ensuring that water distribution is consistent, thus enhancing the overall safety of the space. Maintaining this distance prevents issues such as inadequate coverage, which could lead to ineffective fire suppression and increased risk during a fire event.
