A Comprehensive Guide on Pallet Rack Flue Spaces
Warehouse safety and risk prevention are of paramount importance since different operations carried out in such setups involve a high level of risk. The threat of fire is one serious concern in any warehouse, and finding the right solutions for safeguarding and people and property is necessary. There are several ways to reduce the chance of a fire overtaking, and maintaining pallet rack flue space is widely implemented. Flue spaces are nothing but a clear representation of horizontal and vertical lines along with the racking system between the rack rows, and they also imply the direction of loading. A well-designed pallet racking system must have flue space between pallet loads and upright frames. By keeping the flue space cleared of loads within the pallet rack structure not only safeguards warehouse inventory but serves as a safety measure against fire damage.

Introduction and Importance of Pallet Rack Row Flue Spaces Explained
According to the National Fire Protection Association or NFPA, the flue space is a clear vertical opening within the pallet rack structure. These openings allow vertical lines of sight stemming from the floor up to the ceiling. These spaces act as fire code requirements because they reduce the pallet racks’ damage from fire by allowing fire, heat, and smoke to ventilate upward and quickly activate the sprinkler systems. This warehouse racking structure also allows the water to penetrate down through the multiple layers of stored products. Therefore, it is important to keep flue spaces clear of inventory blockage within the pallet rack structure. This may allow for instant fire suppression and fire detection.
Types of Flue Spaces in Pallet Rack Systems
According to the NFPA flue space requirements standard, two types of flue spaces are considered while designing pallet racks for your warehouse.
- Transverse Flue Space: This is the gap or opening space between the products that are stored parallel to the direction of loading. If the products are stacked less than 6″ from other pallets, then they may be blocking the transverse flue space of pallet racks. Flue keepers are used to prevent the pallets from encroaching into the flue space and improve the working of sprinkler systems. These are designed as per NFPA standards and can be installed in non-standard storage units.
- Longitudinal Flue Space: This is spacing between back-to-back rows of pallets racks. Basically, products loaded far behind on the rack in both rows may result in the blockage of the flue. This can be avoided by applying proper warehouse rack space and flue protection standards.
How to Keep Flue Spaces Clear?
There are many factors that can affect the flue space’s effectiveness in preventing fire spread. With a well-designed pallet racking system and properly sized products, some appropriate safety solutions help in keeping your flue space clear and visible.
- Rack Straps: This is one of the common ways to keep your flue space clear. These straps are attached to the backside of each bay, stopping the pallets from being pushed back into flue space.
- Wire Rack Backing: As the name implies, they are installed on the rear side of the rack. Primarily, they help prevent products from falling off the racking system but can also be used to restrain products from blocking the flue space.
- Pallet Stop Beams: They are bolted into the pallet rack upright from 6” to 12” beam level. This helps stop the products from being pushed back into the flue space.
By now, you may have understood that maintaining the pallet rack flue space is vital for the safety of the warehouse inventory and staff.
