In light hazard occupancies, how long can the room be before additional sprinklers need to be added, if horizontal sidewall sprinklers are across from each other?

In light hazard occupancies, the maximum distance between horizontally opposing sidewall sprinklers is crucial to ensure effective coverage and fire protection. When sidewall sprinklers are installed across from each other, they can effectively protect areas up to a certain distance, which in this case is 24 feet.

This distance allows the sprinklers to effectively distribute water to cover the necessary area and provide adequate suppression for fire incidents that may occur in such environments. The engineering behind this standard takes into account the distribution pattern of water discharged from sidewall sprinkler heads and the need for overlapping coverage to minimize any potential blind spots, which could pose a risk for fire spread.

While other distances might apply to different types of occupancies or different configurations like overhead sprinklers, the 24-foot separation is specifically tailored for light hazard situations with sidewall sprinklers positioned directly across from each other, ensuring that the fire protection system functions effectively within its designed limits.
