The city fire department requires that high pile storage is to be restricted by the amount of fire protection in the warehouse.
San Diego’s Fire Department classifies high pile storage as:
Fire protection includes the overhead sprinkler system, fire hoses, and fire extinguishers. The building’s overhead sprinkler system can be evaluated with the following information:
The storage size and type of commodity being stored is usually limited by the amount of fire protection available. Unless in-rack sprinklers are installed, most warehouse pallet rack require at least 50% open shelving, if the storage system is 12 feet or higher.
Wiremesh decks are used in pallet racks to create a deck on the beam level for material storage while maintaining the Fire Department’s 50% open shelving requirement. Wiremesh decks typically have a galvanized or powder coated finish and can support up to 225 psf.
In-rack sprinklers may be required when solid decking is required. This depends on the size of the storage structure, the type of commodity being stored, and the amount of fire protection in the warehouse. In most cases, we recommend using a Fire Consultant to analyze your fire protection needs.
