- Company Profile:
Established in 1896, NFPA's mission is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus codes and standards, research, training, and education.
The testing, troubleshooting, repair, and/or replacement of a component or subsystem while redundant component(s) or subsystem(s) are serving the load, where the ability to perform concurrent maintenance is critical to attaining the specified reliability/availability criteria for the system or facility.
Industry:Fire safety
Units used by the general working population to afford effective respiratory protection in escaping from hazardous environments. These units can be either air-purifying or self-contained escape respirators.
Industry:Fire safety
The wrapping or enclosure directly containing a glove or face protection device.
Industry:Fire safety
This system is similar to a standard pressure proportioner, except the foam concentrate is contained inside a diaphragm bag that is contained inside a pressure vessel. Operation is the same as a standard pressure proportioner, except that, because of the separation of the foam concentrate and water, this system can be used with all foam concentrates, regardless of specific gravity.
Industry:Fire safety
To restrict the fire within determined boundaries established either prior to the fire or during the fire.
Industry:Fire safety
The space between the top of the finished floor and the underside of a raised floor where used to supply air to the occupied area, or to return or exhaust air from the occupied area.
Industry:Fire safety
The stress in a pipe wall, acting circumferentially in a plane perpendicular to the longitudinal axis of the pipe and produced by the pressure of the fluid in the pipe.
Industry:Fire safety
Those having predetermined flow rates, nozzle pressures, and quantities of extinguishing agent. These systems have the specific pipe size, maximum and minimum pipe lengths, flexible hose specifications, number of fittings, and number and types of nozzles prescribed by a testing laboratory. The maximum and minimum pipe lengths and the number of fittings shall be permitted to be expressed in equivalent feet of pipe. The hazards protected by these systems are specifically limited as to type and size by a testing laboratory, based on actual fire tests. Limitations on hazards that are permitted to be protected by these systems and piping and nozzle configurations are contained in the manufacturer’s listed installation and maintenance manual, which is part of the listing of the system.
Industry:Fire safety
To confirm that a message or signal has been received, such as by the pressing of a button or the selection of a software command.
Industry:Fire safety
The varying pressure at the point of discharge from the compressor.
