Monthly visual checks, annual professional inspections, and multi-year maintenance schedules — everything you need to keep your extinguishers compliant and reliable.
Inspect fire extinguishers monthly (visual check — pressure gauge, damage, pin/seal), annually (by a certified professional), every 6 years (internal maintenance for stored-pressure units), and every 12 years (hydrostatic pressure test). Aerosol units like the LifeSafe StaySafe All-in-1 only need visual checks and expiration date monitoring — no professional servicing required.

A fire extinguisher that doesn't work when you need it is worse than no extinguisher at all — it gives you false confidence and wastes critical seconds. Regular inspection is the only way to guarantee your extinguisher will perform in an emergency. If you're not sure which type you own, our fire classes guide explains the differences between A, B, C, and K extinguishers.
This checklist follows NFPA 10: Standard for Portable Fire Extinguishers and covers the three tiers of inspection every extinguisher owner should know: monthly visual checks (you do these), annual professional inspections, and multi-year internal maintenance. It applies equally to kitchen fire extinguishers, car extinguishers, RV units, and marine extinguishers.
Whether you have a traditional dry-chemical unit from Kidde, First Alert, or Amerex or a compact aerosol extinguisher like the LifeSafe StaySafe All-in-1, this guide has you covered. Already know your unit has failed? See our best small fire extinguisher rankings for a replacement.
Monthly
You (or designated person)
Visual inspection — 8-point checklist below
Annually
Certified fire protection professional
Detailed inspection with internal checks
Every 6 Years
Certified technician
Internal examination & recharge (stored-pressure units)
Every 12 Years
Certified technician
Hydrostatic pressure test (all rechargeable units)
Perform every 30 days. Takes under 2 minutes per extinguisher.
Extinguisher is in designated location
Mounted on wall bracket or in cabinet at correct height (max 5 ft to handle for units over 40 lb, max 3.5 ft for smaller units).
Access is unobstructed
No boxes, furniture, or equipment blocking a 36-inch clearance zone around the extinguisher.
Pressure gauge in green zone
Needle is within the green (charged) band. Overcharged (past green) is also a fail — have it serviced.
No visible damage or corrosion
Check body, handle, hose, and nozzle for dents, rust, cracks, or leaking agent.
Safety pin and tamper seal intact
Pin is present and seal is unbroken. A missing pin suggests possible discharge or tampering.
Operating instructions legible
Label text and pictograms must be readable. Faded labels mean the unit should be relabeled or replaced.
Weight feels correct (lift test)
Lift the unit — it should feel full. A noticeably light extinguisher may have leaked agent.
Inspection tag signed and dated
Initial and date the inspection tag. Maintain a log for compliance records.
Must be done by a certified fire protection technician. Required by NFPA 10 and most local fire codes.
All monthly items verified
A professional annual inspection includes everything in the monthly check, plus additional internal tests.
Internal examination (as required)
Stored-pressure units are checked for proper charge weight. Cartridge-operated units are opened for internal inspection.
Hose and nozzle condition
Hoses are checked for cracks, blockages, and proper connections. Nozzles are cleared of debris.
Cylinder condition
The cylinder is examined for dents deeper than the manufacturer's limits, thread damage, and corrosion.
Tamper indicators replaced
New tamper seal and verification collar installed after professional inspection.
Annual service tag attached
Certified technician attaches a dated service tag confirming the unit passed professional inspection.
Applies to: Stored-pressure extinguishers (dry chemical, wet chemical)
Every 6 years, stored-pressure extinguishers must be emptied, internally examined, recharged, and the valve assembly inspected. This is a full internal service — not just a visual check.
Reference: NFPA 10, Section 7.3
Applies to: All rechargeable extinguishers
Every 12 years, the cylinder undergoes hydrostatic pressure testing to verify structural integrity. Units that fail are condemned and replaced.
Reference: NFPA 10, Section 8.3
Applies to: CO₂ units only
CO₂ extinguishers require hydrostatic testing every 5 years (not 12) due to the higher pressures involved.
Reference: NFPA 10, Section 8.3.1
Compact aerosol units like the LifeSafe StaySafe All-in-1 have a simpler inspection process — no pressure gauge, no professional servicing.
If any inspection reveals these issues, the extinguisher must be taken out of service immediately.
Pressure gauge in the red
Action: Remove from service. Recharge or replace immediately.
Visible corrosion or dents
Action: Have a professional assess. Deep corrosion or dents compromise structural integrity.
Broken or missing tamper seal
Action: Assume the unit may have been partially discharged. Have it weighed and recharged.
Cracked or clogged hose
Action: Replace the hose assembly. A blocked hose means zero discharge in an emergency.
Faded or illegible label
Action: Relabel the unit or replace it. Users must be able to read operating instructions during a fire.
Past expiration date
Action: Replace immediately. Expired units are unreliable and may not discharge properly.
If your inspection revealed a failed unit, the LifeSafe StaySafe All-in-1 is a maintenance-free replacement — no pressure gauge to monitor, no professional servicing required.
Check Price On AmazonA fire extinguisher is only as reliable as its last inspection. Monthly visual checks take under 2 minutes and catch 90% of issues before they become emergencies. Pair this checklist with annual professional inspections and you can trust that every unit will perform when it matters.
