In Rack Sprinkler System Design

Nfpa 13 a design standard for the installation of sprinkler systems.

In rack sprinkler system design.

Good afternoon we are doing a project based on point 25 8 3 of nfpa 13 for a warehouse of 22 meters high of building with 17 meters high of storage in open racks. Treat highest in rack sprinkler system as a virtual floor when selecting ceiling sprinkler system. Specifically designed for the protection of racked storage areas in rack sprinkler systems are manufactured to continuously monitor for smoke and release water into a targeted area to minimize damage and downtime for the facility. In rack fire sprinkler systems are specifically designed for the protection of racked storage areas in warehouses.

What sprinkler system is to be installed. Chapter 12 gives general requirements for esfr in that a minimum of 12 sprinklers are required in the design area four sprinklers on three lines. An in rack sprinkler system is designed to prevent the spread of fire within racking by using heat sensitive heads triggering automatically in the event of a fire and extinguishing the flames. In rack hydraulic design class i iv commodity and cartoned plastics uncartoned plastics single row racks up to 0 9m deep 4 4 single row racks up to 1 8m deep 5 5 double and multiple row racks 6 6 6 not balanced with ceiling sprinkler system.

According to this point the in rack sprinkler system shall not be required to be hydraulically balanced with the ceiling level sprinkler systems we did not find clarification for the calculation of the nominal flow of the pump.

For rack storage of group a plastics refer to chapters 12 and 17 of nfpa for the required design. To ensure that a facility s sprinkler system and racking are properly designed and will work together effectively it is critical to work with a qualified fire protection professional familiar with the pertinent warehouse fire sprinkler design and building codes including.

Traditional in rack sprinkler installations limit the storage height above the top level of sprinklers to 10 feet 3 meters primarily due to the concern that fire growth within the storage rack will reach the top of the array and that the amount of heat from a fire may be too large for the ceiling sprinkler system to control.
