Risk Logic can help you ensure that adequate flue spaces are provided for your facility. However, when items are hand-stacked in racks, these flue spaces become more difficult to maintain visual cues and even physical stops are often needed to ensure proper flue spaces are provided. Solid-shelf storage protection would require a more robust sprinkler system design.įlue spaces are typically fairly easy to maintain with a little bit of operator training when rack storage is on pallets. If these flue spaces are not present, then this storage should be protected as solid-shelf storage. net transverse flue spaces should be provided at least every 9 ft. net transverse flue spaces should be provided at least every 4.5 ft. FM Global Data Sheet 8-9 indicates that 3 in. NFPA 13 indicates transverse flue spaces should be provided between loads and at the rack uprights. If flue spaces are blocked during a fire, sprinkler water will not be able to penetrate through the racks and fire may spread horizontally. Maintain vertical alignment of flue spaces as closely as possible.Įnsure rolled commodities stored in racks are arranged so they cannot bulge into or encroach over flue spaces. (600 mm), treat the space as an aisle for in-rack sprinkler design and installation purposes. If the space between two rack structures is more than 24 in. wide) is not considered a flue space, due to the cross bracing used. In other words, a rack upright (typically 3 in. A flue space’s net width is a measure of its gross width minus any horizontal obstructions, such as rack uprights, located within the flue space. for multiple-row racks) vertically throughout the height of the rack.Įnsure flue spaces are a minimum net width of from 3 in.
If longitudinal flue spaces are present, provide a minimum 3 in. However, longitudinal flue spaces are needed at least every 16 ft. FM Global 8-9, Storage of Class 1, 2, 3, 4, and Plastic Commodities, does not have this height requirement and makes these flue spaces optional for any storage height.
However, these flue spaces are needed for storage exceeding 25 ft (7.6 m) in height. (7.6m) high per NFPA 13, Standard for the Installation of Sprinkler Systems. Longitudinal flue spaces are optional for double-row rack storage up to and including 25 ft. Unless in-rack sprinklers are provided at every storage tier, transverse flue spaces are always needed in rack storage arrangements regardless of building and storage height.
Without enough water reaching the base of a fire on the lower tiers of the racks, the fire may not be controlled.
Flue spaces are also necessary to allow sprinkler water to reach the base of the fire down through the racks. This allows the ceiling-level sprinklers (and in-rack sprinklers if provided) to operate as quickly as possible, and slows down the horizontal fire spread within the rack. Longitudinal flue spaces are spaces between rows of storage perpendicular to the direction of loading.įlue spaces are necessary for rack storage arrangements to allow heat from a fire to vent vertically. Transverse flue spaces are spaces between rows of storage parallel to the direction of loading. There are two types of flue spaces – transverse flues and longitudinal flues. You might have heard someone mention flue spaces for rack storage, and wondered what flue spaces are and why they are needed.įlue spaces are clear lines of sight from the floor up to the ceiling within rack storage areas.
