What is the recommended maximum distance for spacing between standard spray sprinklers in light hazard areas?

The recommended maximum distance for spacing between standard spray sprinklers in light hazard areas is 12 feet. This spacing is established to ensure that the coverage is adequate to control or suppress potential fires effectively, given the characteristics of light hazard occupancies, which typically involve materials with a low amount of combustible content.

In light hazard areas, the risk of fire escalation is lower, allowing for closer spacing of the sprinklers. Setting the maximum spacing at 12 feet provides a balance between coverage and efficiency, allowing for optimal water distribution. This ensures that the sprinkler system can adequately maintain the necessary water flow and pressure to suppress fires that may arise in such environments.

In contrast, other distances like 10 feet, 15 feet, and 20 feet may not provide the same level of assurance regarding effective coverage under varying conditions. Use of these distances could lead to incomplete coverage and potentially compromise the effectiveness of the sprinkler system in controlling a fire.
