What is the required sprinkler spacing for a sprinkler system installed in a high-hazard occupancy?

In high-hazard occupancies, the protection requirements are more stringent due to the potential fire load and the risk associated with contents or processes present in these environments. The National Fire Protection Association (NFPA) guidelines, specifically NFPA 13, detail the sprinkler spacing requirements based on the classification of hazards.

For high-hazard occupancies, the required spacing is generally set at a maximum of 10 feet between sprinklers. This closer spacing is intended to ensure that the system can effectively control or suppress a fire early in its development, minimizing damage and enhancing life safety.

Understanding this requirement is critical for ensuring that the sprinkler system is designed to meet the potential challenges posed by high-hazard materials or activities, which could include flammable liquids or combustible dusts. Proper spacing helps to achieve adequate water distribution and coverage to control fires within these environments effectively.
