The NFPA 10 inspection checklist for portable extinguishers
Reviewed July 2026
The annual maintenance under NFPA 10 is a hands-on walk of each portable extinguisher. Here is the itemized version a technician runs, unit by unit, before a fresh dated tag goes on.
Location and access
The extinguisher is in its assigned location and mounting. It is visible, reachable, and nothing is blocking it. The signage above it is present and readable.
Condition of the unit
The pressure gauge reads in the operating (green) range. The pull-pin is seated and the tamper seal is intact. The hose, nozzle, and horn are clear and undamaged. The shell shows no corrosion, dents, or leakage. The nameplate and operating instructions are legible.
Weight and charge
The unit is at or near its full rated charge, with no sign of a partial discharge since the last visit.
Records and dates
The manufacture date is captured, so the internal and hydrostatic cycles are anchored correctly. The prior service tag is read and reconciled with the schedule. A new dated tag records the date, the result, the next-due date, and the technician.
What happens when something fails
Anything out of range becomes a documented deficiency, not a guess: a low gauge flags a recharge, an overdue shell flags a hydrostatic test, damage flags a repair or replacement. The remedy is quoted; you set the price.
Cadences vary by jurisdiction — verify with your AHJ. This is a working checklist to adapt to your authority's adopted edition, not a substitute for it.
