NFPA 14 permits Class I standpipe systems to be manual wet systems for buildings not classified as a high-rise, therefore all further discussions in this article will be based on the requirements for a Class I wet manual standpipe system. In most buildings the standpipe system can be designed as a Class I system due the provision of Exception I to Section 905.3.1 of the IBC for buildings protected throughout by automatic sprinkler systems. Under IBC Section 905.3.1, “Height,” that requires a standpipe be installed throughout buildings as discussed previously, the required type of standpipe is a Class III system. hose connections. These systems can then be designed as a combination of a wet, dry, automatic, manual, or semiautomatic system as defined and required by NFPA 14. hose connections, and Class III systems designed for use by trained personnel or fire departments with both 1 ½-in. hose connections, Class II systems designed for use by trained personnel or fire departments with 11/2-in. NFPA 14 identifies three classes of standpipe systems: Class I systems designed for use by fire departments with 2 ½-in. What Type of Standpipe System is Required? If the building does not meet any of the eight criteria listed above, a standpipe system is not required by the IBC. Buildings with a helistop and heliports.Buildings that contain a stage greater than 1,000 ft2.A building that has an assembly occupancy with an occupant load exceeding 1,000.Other uses for which the IBC requires a standpipe system are: The level of fire department apparatus access is defined as the actual location of the fire department apparatus relative to the building, not the access level for the fire department personnel entering to the building. The pertinent section of the IBC is 905.3, “Required Installations.” Most standpipe systems are installed due to the requirement under Section 905.3.1, “Height.” It requires a Class III standpipe be installed throughout buildings where the floor level of the highest story is located more than 30 ft above the lowest level of fire department access, or where the lowest floor level is located more than 30 ft below the highest level of fire department vehicle access. All further references to NFPA 14 in this article will be to the 2013 edition. In the 2015 IBC the applicable version of NFPA 14 is the 2013 edition. Chapter 35 of the IBC contains the applicable version of standards referenced within the text of the IBC. The majority of installation requirements for a building standpipe system will be contained in NFPA 14 as referenced by the IBC. The current edition of the IBC is 2015, therefore all further references to the IBC will be to the 2015 edition.

In the majority of states and cities within the United States, the adopted building code will be an edition of the International Building Code (IBC), which may be adopted in full or adopted with modifications and then becomes the state or city building code. The requirements for a building standpipe system are contained within the adopted building code for that jurisdiction.
Required Installation and Installation Requirementsĭuring the design of a building two questions must be answered to determine the requirements for a standpipe system: How is the fire department apparatus defined and used in a hydraulic calculation?.Which outlets are flowed in a hydraulic calculation?.What are the requirements for the fire department connection (FDC)?.What is the required flow rate of the system?.What is the required pressure at the hose outlet(s)?.Where are the required hose outlets located?.What type of standpipe system is required?.When are standpipes required and what are the installation requirements?.This article will attempt to simplify the requirements for these systems by addressing the following issues: Although the requirements for standpipe systems are contained in the adopted building code and the installation requirements are contained within the referenced edition of NFPA 14, Standard for the Installation of Standpipe and Hose Systems, there is often disagreement between the responsible design professional, the fire protection contractor, and the Authority Having Jurisdiction (AHJ) on the proper design and installation of the system.
