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 maximum flow rate of exposedthat a route or path can handle.
Industry:Fire safety
The intentional connection to earth through a grounding electrode of sufficiently low impedance to minimize damage to electrical components and prevent an electric shock that can occur from a superimposed voltage from lightning and voltage transients. In addition, earth grounding helps prevent the buildup of static charges on equipment and material. It also establishes a common voltage reference point to enable the proper performance of sensitive electronic and communications equipment.
Industry:Fire safety
The length from face of portal to face of portal that is measured using the centerline alignment along the tunnel roadway.
Industry:Fire safety
The maximum number of personnel or activities that can be effectively controlled by one individual (usually three to seven).
Industry:Fire safety
The lowest temperature at which a combustible material ignites in air without a spark or flame.
Industry:Fire safety
The lowest temperature at which a liquid will ignite and achieve sustained burning when exposed to a test flame in accordance with ASTM D 92, Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester.
Industry:Fire safety
The likelihood of an event as expressed as a number between 0 and 1.
Industry:Fire safety
The maximum clearance between two parallel metal surfaces that has been found, under specified test conditions, to prevent an explosion in a test chamber from being propagated to a secondary chamber containing the same gas or vapor at the same concentration.
Industry:Fire safety
The maximum designated rms value of the power frequency voltage that can be continuously applied to the mode of protection of a surge protective device (SPD).
