The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association . [ 1 ]
A process to perform a water flow test is explained in the model fire codes as published by NFPA (National Fire Protection Association). If a water supply source is considered weak compared to what is required by the sprinkler system design hydraulic calculation, the water pressure can be boosted by means of a fire pump.
Conserve Water During Testing – NFPA-25 requires that the fire pump controller is operated for 10 minutes each week. This ends up using a substantial amount of water in buildings that have static pressures greater than 175 PSI and relies on a system relief valve to control the pressure: (50–100% of the rating of the pump) × (10minutes) × ...
In the US, the independent National Fire Protection Association (NFPA) publishes several relevant standards, and they are often adopted by government agencies. Guidance on assessment of hazards is given in NFPA 497 (explosive gas) and NFPA 499 (dust). The American Petroleum Institute publishes analogous standards in RP 500 and RP505.
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 ...
NFPA 70E (Standard for Electrical Safety in the Workplace) is a standard of the National Fire Protection Association (NFPA). The document covers electrical safety requirements for employees. The NFPA is best known for publishing the National Electrical Code (NFPA 70).
A jockey pump, also known as a pressure-maintenance pump, is a small pump connected to a fire suppression system near the fire pump and is intended to maintain pressure in a fire protection piping system. These pumps recover pressures lost from gradual, slow pressure declines in a system due to temperature changes, trapped air escapement, or ...
NFPA 70B (Standard for Electrical Equipment Maintenance) is a standard of the National Fire Protection Association that addresses preventive maintenance for electrical, electronic, and communication systems and equipment—such as those used in industrial plants, institutional and commercial buildings, and large multi-family residential complexes—to prevent equipment failures and worker ...
