NFPA 12A Standard on Halon 1301 Fire Extinguishing Systems 2025 Edition

Support safe, knowledgeable, and effective Halon 1301 fire extinguishing system inspection, maintenance, and decommissioning. NFPA 12A, Standard on Halon 1301 Fire Extinguishing Systems, presents requirements for halogenated agent systems so equipment can function as intended throughout its service life. Primarily present in commercial, industrial, institutional, marine, and military installations, Halon 1301 (bromotrifluoromethane, or CBrF3) is a colorless, odorless, electrically nonconductive gas that is an inerting agent. Halon 1301 fire extinguishing systems require proper care for safety and effectiveness, and NFPA 12A is a critical resource for skilled workers. It covers system design, installation, testing, and more, including:

• Enclosure integrity procedures
• Hazards to personnel
• Storage containers
• Piping
• System flow calculations
• Approval of installations
