You probably already understand the importance of a clear, well-maintained flue space. While keeping transverse flue space clear is important, keeping longitudinal flue space clear is also vital for safety. It allows heat from a fire to vent upward and activate ceiling sprinklers, preventing a fire from spreading across your warehouse.
In fact, the National Fire Protection Association (NFPA) Code 13 shows the results of several tests determining the dangers of blocked flue spaces. The results of these tests show that blocked longitudinal flue space prevents ceiling fire sprinklers from working effectively. So what are the flue space requirements for effective, clear flue space?
What Makes a Flue Space “Clear”?
Clear flue spaces don’t have pallets or products that have been pushed through from the rack where they are stored. In addition, the NFPA denotes that a 6-inch separation between racks is required for effective ceiling fire sprinkler spread.
This amount of space allows fire and heat to vent upward instead of out, which activates sprinkler systems more quickly. It also allows the sprinkler water to reach the base of the fire down through the racks more efficiently.
Typically, most pallet rack systems are designed with even spacing between loads and upright frames. However, it is important to measure this distance during routing safety checks to maintain the proper 6-inch separation.
How to Keep your Flue Space Clear
Poor rack design, deep pallet loads, and pallet push through can impact your flue space’s effectiveness in preventing fire spread. In addition to ensuring you have a well-designed rack system and correctly sized pallets, proper safety solutions help make keeping your flue space clear simple.
