The committee's initial report evolved into NFPA 13, Standard for the Installation of Sprinkler Systems, the most widely used fire sprinkler standard. [ 6 ] Around 1904, the NFPA began to expand its membership from affiliates of fire insurance companies to many other organizations and individuals, and also expanded its mission beyond ...
The 2002 edition of the NFPA #13 standard, section 3.6.1 defines quick response sprinklers as having a response time index (RTI) of 50 (meter-seconds) 1/2 or less. RTI is a measure of how thermally responsive the heat-responsive element of the sprinkler is, measured as the time needed to raise the temperature of the sprinkler bulb to 63% of the ...
A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available ...
The hydraulic calculation procedure is defined in the applicable reference model codes such as that published by the US-based National Fire Protection Association (NFPA), [2] or the EN 12845 standard, Fixed firefighting system – Automatic sprinkler systems – Design, installation and maintenance. [3]
This organization writes codes, regulations, and recommendations on the proper installation and maintenance of these fire suppression systems. Likewise, the NFPA also lists criteria that must be met for the requirements of certain types of fire suppression systems. [2]
A typical automatic sprinkler system operates when heat at the site of a fire causes a fusible link or glass component in the sprinkler head to fail, thereby releasing the water from the sprinkler head. [5] This means that only the sprinkler heads at the fire location actuate – not all the sprinklers on a floor or in a building.
The Certified Fire Protection Specialist (CFPS) is a certification provided by the NFPA Certification Department in the U.S.A. [1] The board was formed in 1971 and in 1998 partnered with the National Fire Protection Association (NFPA) to offer the professional certification.
In fire protection engineering, the K-factor formula is used to calculate the volumetric flow rate from a nozzle. Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
