#277 – Guide to Fire Hose Reels and Racks for Standpipe and Hose Systems
Leading fire and building codes have pushed indoor hose installations to the margins, but their use (and usefulness) endures
Fire hose reels and fire hose racks are part of certain standpipe and hose systems—but many jurisdictions are slowly phasing them out. Leading fire and building codes from the National Fire Protection Association (NFPA) and the International Code Council (ICC) have gradually minimized the role of “occupant-use” hose in fire safety—and newer editions of these codes grant building owners greater flexibility in removing them from their systems.
In this article, we look at fire hose reels and fire hose racks, explaining their role in standpipe and hose systems, what they’re made of, and why some buildings still have them. We take a look at the International Building Code (IBC) and various NFPA codes to help building owners determine their options for installation, repair, or planned obsolescence.
For additional information on standpipe systems, check out this post at Aaron Johnson’s The Code Coach, a leading resource for codes, standards, and recommended practices in a range of fire protection systems.

Some standpipe and hose systems have long made hoses available to a building’s occupants, but users may not know when to quit
A fire doubles in size every 120 seconds. Or is it every 60 seconds? Every 30? 15?
Depending on the fire and the characteristics of the building, any one of these answers may be right. That’s a problem for firefighters—even with training and experience—but it’s an even bigger problem for a building’s everyday occupants.
In a standpipe system, fire hose racks and fire hose reels allow a building’s occupants to engage in what’s sometimes called “first-aid firefighting.” In the early, or “incipient,” stages of a fire, the surrounding air has plenty of oxygen to feed it. Hot flame and gas mix with cool air, increasing overall temperatures. The fire remains in a small area—with flames lower than ceiling height—and only some smoke is visible.
Left alone, a fire will rapidly progress to the growth stage, where flames may begin to travel across the ceiling. A layer of hot smoke begins to build overhead. And then, with little warning, the fire may become fully developed, with a ballooning rate of heat release and ceiling temperatures approaching or exceeding 1,000 degrees Fahrenheit.
To catch those fires before they enter the growth stage, some standpipe and hose systems feature hose stations. They’re small enough to be handled by people who aren’t expert firefighters, and powerful enough to extinguish fires that haven’t yet established a foothold.
Still, these assemblies can’t deliver water quickly enough for full-scale firefighting. And with fire being difficult to predict (and hard to contain), the organizations that develop global fire safety standards have become increasingly uneasy about making fire hose reels and racks available to a building’s occupants.
Hose stations for occupant use are found in some Class II and Class III standpipe and hose systems
Not all standpipe systems have fire hose racks (or reels). For guidelines on their installation, fire protection contractors rely on NFPA 14: Standard for the Installation of Standpipe and Hose Systems. This standard divides standpipe systems into three types:
From the 2015 edition of NFPA 14
220.127.116.11 Class I System. A system that provides 2 1/2 in. (65 mm) hose connections to supply water for use by fire departments.
18.104.22.168 Class II System. A system that provides 1 1/2 in. (40 mm) hose stations to supply water for use primarily by trained personnel or by the fire department during initial response.
22.214.171.124 Class III System. A system that provides 1 1/2 in. hose stations to supply water for use by trained personnel and 2 1/2 in. hose connections to supply a larger volume of water for use by fire departments.
Hose connections are valves without hose attached; hose stations have fully equipped fire hose reels or racks. These descriptions suggest that all Class II and Class III systems feature the latter. However, NFPA 14 later states that a hose connection may replace a hose station in a Class II system. Likewise, a Class III system may omit hose stations if the building has a fire sprinkler system.
From the 2015 edition of NFPA 14
5.3.2 Class II Systems
126.96.36.199 A Class II standpipe system shall provide either 1 1/2 in. (40 mm) hose stations to supply water for use by trained personnel or a hose connection for the fire department during initial response.
5.3.3 Class III Systems
188.8.131.52 Where the building is protected throughout by an approved automatic sprinkler system, Class II hose stations for use by trained personnel shall not be required, subject to the approval of the AHJ, provided that each Class I hose connection is 2 1/2 in. (65 mm) and is equipped with a 2 1/2 in. x 1 1/2 in. (65 mm x 40 mm) reducer and a cap attached with a chain.
Fire hose reels and racks may be needed in buildings with several stories underground or aboveground, and in other locations specified by building codes
Class III standpipe and hose systems, while common, rarely need hose stations—and Class II systems are nearly nonexistent in the most current building codes
NFPA 14 provides the requirements for standpipe and hose systems—but in most jurisdictions, some version of the ICC’s International Building Code (IBC) dictates which structures require a standpipe system. Tall buildings or buildings with deep basements generally require Class III standpipe systems.
From the 2018 edition of the International Building Code
[F] 905.3.1 Height.
Class III standpipe systems shall be installed throughout buildings where any of the following conditions exist:
1. Four or more stories are above or below grade plane.
2. The floor level of the highest story is located more than 30 feet (9144 mm) above the lowest level of fire department vehicle access.
3. The floor level of the lowest story is located more than 30 feet (9144 mm) below the highest level of fire department vehicle access.
There are some exceptions to this rule. Class I systems—which don’t feature hose stations—may be installed in place of Class III systems when buildings have automatic fire sprinkler systems throughout.
They may also be used in certain buildings or portions of buildings that have reduced fire risk or conditions that make installing water-filled piping impractical. And, as we mentioned in the prior section, Class III systems with an NFPA-compliant fire sprinkler system may eliminate their hose stations if they put a cap and chain, along with a reducer, in its place.
No new building under the 2015 or 2018 edition of the IBC needs a Class II standpipe system. Section 905.5 of the 2015 edition calls for 1 1/2” hoses for unsprinklered stages greater than 1,000 square feet—as part of a Class III system—which is about as close as the IBC gets to requiring a Class II system.
Accessible placement and careful measurement of distances are needed any time a fire hose rack or reel is installed with a Class II or Class III system
In the Fire Protection Handbook, professional engineer David R. Hague writes that standpipe systems with permanent hose stations “should be located in central areas… where they are clearly visible and readily accessible.” Hose stations must be placed between three and five feet above the floor, as measured from the floor to the center of the hose valve (NFPA 14, sections 184.108.40.206 – 220.127.116.11.1).
Section 18.104.22.168 of NFPA 14 restricts the maximum length of the included hose to 100 feet. Working within that limit, designers of Class II systems must provide enough properly placed hose stations to provide coverage.
From the 2015 edition of NFPA 14
7.3 Locations of Hose Connections.
22.214.171.124 Class II systems shall be provided with 1 1/2 in. (40 mm) hose stations so that all portions of each floor level of the building are within 130 ft (39.7 m) of a hose connection provided with 1 1/2 in. (40 mm) hose or within 120 ft (36.6 m) of a hose connection provided with less than 1 1/2 in. (40 mm) hose.
126.96.36.199 Distances shall be measured along a path of travel originating at the hose connection.
These distances—130 feet for 1 1/2” hose and 120 feet for smaller sizes—account for the reach of the nozzle. They’re measured using the “actual length method,” which considers the reach of the stream as the hose bends around doors, corners, and obstructions. While the hose length provision (100 feet maximum) applies to both Class II and Class III systems, section 188.8.131.52 doesn’t apply to hose stations in Class III systems (184.108.40.206.1).
Stations in standpipe and hose systems consist of a few simple components—and a variety of code requirements
Most hose stations installed in accordance with NFPA 14 consist of the following components:
- Closets or cabinets designed to store occupant-use hose, and which clearly indicate its location
- Fire hose racks or reels, which store hose and allow for quick deployment
- Hose connections, which join the standpipe system to the hose itself
- Fire hoses and hose nozzles used in incipient-stage firefighting
All hose stations include the last three items (the rack/reel, hose connection, and hose/nozzle) by definition. Closets or cabinets, while often provided, aren’t explicitly required.
Closets and cabinets must facilitate easy access to hose connections
In section 4.6.1, NFPA 14 lists the following requirements for closets and cabinets used with hose stations:
- They must be large enough that they don’t slow the “prompt use” of hose connections, hoses, and associated equipment
- 2” of clearance must be provided between any part of the cabinet (excluding the door) and a hose connection at all times—even when the valve is fully opened
- Cabinets may only store fire equipment and must be clearly identified, with their contents marked
- Devices used to open “break glass” panels must be attached “in the immediate area” of the panel and “arranged so that the device cannot be used to break other glass panels in the cabinet door”
- Safety glazing must consist of tempered safety glass or plastic glazing conforming with ANSI Z97.1, a standard designed to reduce the likelihood of injury if glass breaks
- Cabinets must not interfere with the fire resistance of surrounding assemblies
Additionally, a label with the words “FIRE HOSE FOR USE BY TRAINED PERSONNEL,” along with operating instructions, must be included if the rack or reel itself does not include them (section 4.6.5).
Listing is a core requirement for fire hose reels or racks—and reels are required for small hoses
Section 4.6.3 provides NFPA 14’s requirements for the fire hose racks or fire hose reels that safely store hoses. Each station with 1 1/2” hose needs a “listed rack or approved storage method”—meaning that the rack needs certification by a third party or the approval of the AHJ.
If the hose is less than 1 1/2” in size, it should be stored on a “listed continuous flow reel.” As the name suggests, continuous flow reels ensure that the hose can discharge water as soon as the valve opens—even if the hose is partially coiled. If the fire hose is not stored in a closet or cabinet, racks and reels must include a label with the words “FIRE HOSE FOR USE BY TRAINED PERSONNEL” along with the station’s operating instructions (4.6.5).
1 1/2” hoses and nozzles are standard, but smaller alternatives may be used
NFPA 14’s requirements for hoses are contained in section 4.6.2, while their requirements for nozzles are found in section 4.6.4. All nozzles must be listed, and hoses must follow one of two requirements, depending on their size:
- 1 1/2” hose: Each must be listed, lined, ready for use, and no longer than 100 feet. They may be collapsible (able to lay flat) or non-collapsible (maintaining their shape when stored).
- Sizes under 1 1/2”: Smaller hoses must be listed and non-collapsible.
Smaller hoses—which may be used only in light-hazard occupancies—must be at least 1” in diameter. They must be listed and approved by the AHJ. These restrictions apply to both Class II and Class III systems (sections 220.127.116.11 and 18.104.22.168).
The standpipe systems of the future will have fewer fire hose racks and reels
The ICC has slowly rolled back requirements for both Class II and Class III standpipe systems. Building owners’ failure to maintain hoses, employers’ “sporadic” training of employees on hose use, and the increasing presence of fire sprinkler systems in structures make the use of these hoses less necessary and potentially hazardous.
In recent years, the International Code Council (ICC) has provided fire officials with new guidance on the removal of occupant-use hose lines. The 2018 edition of the International Fire Code (IFC) allows fire code officials to remove hose stations’ fire hoses if both of the following conditions are true:
- The hose line won’t be used by trained staff or firefighters
- The included hose outlets are compatible with the local fire department’s hoses
- NFPA 1 or current building codes don’t require their installation
- The authority having jurisdiction (AHJ) determines that the hose won’t be used by trained personnel or the fire department
These provisions, when adopted, may be implemented in slightly different ways. The San Jose Fire Department, for example, requires that building owners apply for a permit before removal. Then, they must have their system inspected, tested, and maintained by a licensed contractor.
Note that neither of these standards allows for removal of other standpipe system components—just the hoses, fire hose reels and racks, and fire hose nozzles. Hose connections are left intact.
Fire hose racks and fire hose reels still have a place in settings where they’re needed and can be safely used
Rather than encouraging some trained occupants to contain fires in their early stages—as is already done with fire extinguishers—today’s fire officials would rather ensure that evacuation takes place as quickly and safely as possible. While that’s good as a general rule, there are still some uses for hose stations.
First, while building owners can remove these systems, there’s no mandate to do so. In some jurisdictions—particularly those that haven’t updated their fire codes in some time—occupant-use hoses may be required. Second, even when removal is an option, hose stations may still be useful. An on-site fire brigade can use hose stations to safely extinguish fires while the rest of a building’s occupants evacuate. And when hot work is a common occurrence or occurs alongside fire sprinkler system impairment, fire hose racks and reels can provide a useful supplement to other fire protection measures.
Finally, local fire departments may use 1 1/2” hose connections to supplement more robust firefighting efforts. Smaller hose sizes minimize water discharge—meaning that firefighters can soak mostly-extinguished fires and clean up the debris while reducing water damage.
