How are sprinkler systems designed for special hazards addressed in NFPA 13?

Sprinkler systems designed for special hazards in NFPA 13 have additional criteria specific to each hazard type because these types of hazards often present unique challenges that require tailored solutions. For example, a facility that stores flammable liquids will have different risks compared to an area with ordinary combustibles. The standard takes into account these differences and provides detailed guidance to ensure adequate protection.

By addressing special hazards with specific design criteria, NFPA 13 helps ensure that sprinkler systems are effectively calibrated to meet the risks associated with various materials and operational processes. This targeted approach helps mitigate the potential for fire and damage by ensuring that the response of the sprinkler system is appropriate for the specific circumstances.

Other approaches, such as treating these hazards the same as standard hazards or allowing them to be governed solely by local fire codes, do not adequately account for the complexities associated with special hazards, which could lead to insufficient protection and increased risk during a fire event.
