    The publication Life Safety Code, known as NFPA 101, is a consensus standard widely adopted in the United States. [according to whom?] It is administered, trademarked, copyrighted, and published by the National Fire Protection Association and, like many NFPA documents, is systematically revised on a three-year cycle.

    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 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 ]

    NASA also references Safety Standard for Hydrogen and Hydrogen Systems [110] and the Sourcebook for Hydrogen Applications. [ 111 ] [ 106 ] Another organization responsible for hydrogen safety guidelines is the Compressed Gas Association (CGA) , which has a number of references of their own covering general hydrogen storage, [ 112 ] piping ...

  7. Extra-low voltage - Wikipedia

    en.wikipedia.org/wiki/Extra-low_voltage

    The single-phase voltage is 110 V a.c. though having a "centre tapped Earth" reducing the voltage to earth to 55 V AC. The three-phase system is 110 V phase-to-phase and 63 V to neutral / earth. This system voltage is slightly above the ELV limit, but is still very commonly used for cord-powered hand tools and temporary lighting in hazardous areas.

  8. Fire test - Wikipedia

    en.wikipedia.org/wiki/Fire_test

    A fire test is a means of determining whether fire protection products meet minimum performance criteria as set out in a building code or other applicable legislation. Successful tests in laboratories holding national accreditation for testing and certification result in the issuance of a certification listing .

  9. High voltage - Wikipedia

    en.wikipedia.org/wiki/High_voltage

    If the power supply and load allow sufficient current to flow, a self-sustaining arc may form. Once formed, an arc may be extended to a significant length before breaking the circuit. Attempting to open an inductive circuit often forms an arc, since the inductance provides a high-voltage pulse whenever the current is interrupted.
