    Abstract - (Show below) - (Hide below)

    Specifies requirements for total flooding fire extinguishing systems, utilizing halon 1301 (bromotrifluoromethane (CF(sub)3(/sub)Br)) as the extinguishing medium, for use in enclosed spaces. It applies to single supply or distributed supply systems. The Standard contains requirements for concentration, protected enclosures, quantity, halon 1301 supply, distribution system control systems and marking.

    Scope - (Show below) - (Hide below)

    This Standard sets out requirements for total flooding fire extinguishing systems, utilizing halon 1301 (bromotrifluoromethane (CF3Br))asthe extinguishing medium, for use in enclosed spaces. It applies to single supply or distributed supply systems.NOTE: Passages in this Standard indicated by a marginal line are reprinted from NFPA 12A-1985. See Preface.
