What is the maximum square footage that a standard spray sprinkler can be spaced in a light hazard occupancy?

In a light hazard occupancy, the spacing requirements for standard spray sprinklers are crucial for ensuring effective fire protection. The maximum area that a standard spray sprinkler can cover is typically 225 square feet. This spacing is based on NFPA (National Fire Protection Association) guidelines, which dictate that a single sprinkler can be effective up to this limit in environments classified as light hazards, such as offices or other similar settings where combustible materials are limited.

This maximum coverage ensures that the sprinkler can respond efficiently to a fire incident, providing adequate water distribution to control or extinguish a fire within the designated area. The decision to allow up to 225 square feet is based on the assumption that the materials present in light hazard occupancies will not contribute significantly to fire spread, thus allowing for slightly larger coverage compared to higher hazard classifications.

Understanding these types of specifications is essential for sprinkler fitters, as they must adhere to local codes and standards to ensure safe and effective fire protection installations.
