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.

2024 edition updates are:

• New Annex B detailing common deficiencies and impairments.
• Definitions of deficiency and impairment have also been added to clarify how users should differentiate between these two types of issues.
