Internal maintenance required every 6 years: full discharge, refill, valve replacement, O-ring service, leak testing, and compliance sticker application by a licensed company.
NFPA 10 requires that stored-pressure fire extinguishers undergo a complete internal maintenance inspection every 6 years. This goes beyond the standard annual inspection — the extinguisher must be fully discharged, internally inspected, refilled, and recertified by a licensed technician. Skipping this service can result in FDNY violations and failed inspections.
A fire extinguisher that passes annual visual inspection may still have internal degradation that prevents it from functioning when needed. The six-year internal maintenance ensures every component is verified, replaced as necessary, and documented — keeping your property safe and your business FDNY-compliant.
