    Make sure dry chemical fire suppression systems are ready to function as intended in emergencies with NFPA 17.

    In the event of a fire, on-site extinguishing equipment plays a vital role in limiting injuries and life and property loss. NFPA 17, Standard for Dry Chemical Extinguishing Systems, delivers comprehensive requirements for designing, installing, testing, inspecting, operating, recharging, and maintaining these critical fire safety systems.

    The standard covers all aspects and components of dry chemical extinguishing systems throughout their life cycles, such as detectors, nozzles, operating devices, and storage containers.

    Criteria address the full range of dry chemical extinguishing systems, including:

    • Total flooding
    • Local application
    • Hand hose line
    • Engineered
    • Pre-engineered systems

    The 2021 edition offers critical new requirements for dry chemical extinguishing system protocols.

    NFPA 17 presents the design considerations applicable to fire suppression systems that discharge dry chemical from fixed nozzles and piping or hose lines by means of an expellant gas. Manufacturers, contractors, installers, AHJs, and others concerned with dry chemical extinguishing systems get the essential information and requirements necessary for using the standard in the workplace.

    The updated edition provides new provisions consistent with NFPA 12, Standard on Carbon Dioxide Extinguishing Systems, and NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, on the methods for supporting pipe. It also addresses provisions on a common failure of special hazard fire-extinguishing systems, consistent with NFPA 72®, National Fire Alarm and Signaling Code®, and NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems.

    Get the information you need to help eliminate costly errors and oversights and protect lives and property.

    NFPA 17, Standard for Dry Chemical Extinguishing Systems, provides the minimum requirements for dry chemical extinguishing systems. Help ensure compliance at your job site or facility by ordering your copy of the 2021 edition today.
