The National Fire Protection Association (NFPA) is a U.S.-based international nonprofit organization devoted to eliminating death, injury, property, and economic loss due to fire, electrical, and related hazards. [2][3] As of 2023, the NFPA claims to have 50,000 members and 9,000 volunteers working with the organization through its 250 ...
Fire hose. Indoor fire hose with a fire extinguisher. A fire hose (or firehose) is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine, fire hydrant, or a portable fire pump. [1] Indoors, it can permanently attach to a building's standpipe or ...
A water flow test, also known as a hydrant flow test, [1] is a way to measure the water supply available at a building site, usually for the purposes of installing a water based fire protection system (fire sprinkler system). The most common test involves measuring the flow of water flowing out of a municipal fire hydrant (measured in litres or ...
Hydraulic calculations indicate that the combination of the two primary components of a water based fire protection system will meet the design objectives to control, suppress, or extinguish a fire: The available water supply is sufficient in flowrate and pressure. The pipe sizes and piping network arrangement that deliver the water to the ...
1-inch hose with 1-8 NH NFPA threads (NFPA 1963 requirement; a.k.a. "Chemical Hose Thread" and "Booster Hose Thread" [7]; the chemical hose thread term likely originates from its use on chemical fire engines, an early firefighting device used from 1872 until the 1930s that used a combination of bicarbonate of soda and sulfuric acid to force ...
Fire hydrant. A fire hydrant, fireplug, firecock (archaic), [1] hydrant riser or Johnny Pump[2] is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. Underground fire hydrants have been used in Europe and Asia since at least the 18th century.
Fire pumps are used to increase the pressure of water sourced from a municipal underground water supply piping network, or a static supply (e.g., tank, reservoir, lake). A fire pump is a centrifugal- or positive displacement- pump that has been tested and listed by a third-party testing and listing agency, such as UL or FM Global specifically ...
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, onto which fire sprinklers are connected. Although historically only used in factories and large commercial buildings, systems for homes and small buildings are now ...
