What is the maximum square footage of a standard spray sprinkler in an ordinary hazard occupancy?

In an ordinary hazard occupancy, a standard spray sprinkler is rated to cover a maximum square footage of 130 square feet. This setting is designed for environments where there is a moderate hazard level, meaning that there are combustible materials present but not in quantities or configurations that would create a high hazard scenario.

The 130-square-foot coverage limit allows for adequate water distribution to effectively suppress fire based on the specific design of ordinary hazard areas. This is established by fire protection codes and standards, which dictate sprinkler system design to ensure effective fire suppression capabilities in various occupancy types.

The other square footage values cited, such as 225, 100, and 90, do not align with the established coverage area for standard spray sprinklers in typical ordinary hazard environments. Each of these numbers is associated with different conditions or types of sprinkler designs. Therefore, recognizing that the maximum coverage for this specific application is 130 square feet is crucial for ensuring effective fire protection and adherence to safety regulations.
