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 value in amperes to be used instead of the rated-load current in determining the ratings of motor branch-circuit conductors, disconnecting means, controllers, and branch-circuit short-circuit and ground-fault protective devices wherever the running overload protective device permits a sustained current greater than the specified percentage of the rated-load current. The value of branch-circuit selection current will always be equal to or greater than the marked rated-load current.
Industry:Fire safety
Two or more flexible insulated conductors enclosed in a flexible covering that provides mechanical protection.
Industry:Fire safety
Use of a solid or liquid hazardous material in a vessel or system that is continuously open to the atmosphere during normal operations and where vapors are liberated, or the product is exposed to the atmosphere during normal operations.
Industry:Fire safety
Wood from felled trees having a section produced by lengthwise sawing or chipping of logs or other solid wood of large dimensions and possible crosscutting and/or further machining to obtain a certain size and includes boards, dimension lumber, timber, and similar wood products.
Industry:Fire safety
To remove an unserviceable item and install a serviceable counterpart in its place.
Industry:Fire safety
Wood particulate with a median diameter of 420 microns or smaller (i.e., material that will pass through a U. S. No. 40 Standard Sieve), having a moisture content of less than 25 percent (wet basis).
Industry:Fire safety
These optical fiber cables contain non-current-carrying conductive members such as metallic strength members, metallic vapor barriers, and metallic armor or sheath.
Industry:Fire safety
Tread designed to provide maximum traction for all types of surfaces, including sand, mud, snow, ice, and hard surfaces, wet or dry.
Industry:Fire safety
Those control circuits either entering or leaving the fire pump controller enclosure, which if broken, disconnected, or shorted will not prevent the controller from starting the fire pump from all other internal or external means and can cause the controller to start the pump under these conditions.
