Fire extinguisher inspections aren't glamorous, but they're required - and they matter. I've seen buildings fail fire marshal inspections because someone forgot to document the monthly checks, even though they swore the checks were done.
The documentation is the proof. If it's not written down, it didn't happen - at least as far as your insurance company and the fire marshal are concerned.
This checklist covers both monthly visual inspections and the annual maintenance requirements under NFPA 10. Use it as-is or adapt it to your needs.
Monthly Visual Inspection Checklist
NFPA 10 requires monthly inspections of all portable fire extinguishers. These are quick visual checks - you're not discharging or servicing the extinguisher.
Extinguisher Identification
- Extinguisher ID / Asset tag
- Location (building, floor, area)
- Manufacturer
- Model number
- Serial number
- Type (ABC, BC, K, water, CO2)
- Size / Capacity
- Manufacture date
- Last service date
This identification data should only need to be captured once per extinguisher, then pre-populated for subsequent inspections. If you're typing serial numbers every month, your process needs work.
Location and Access
- Extinguisher in designated location (yes / relocated / missing)
- Location signage visible (yes / obscured / missing)
- Access clear and unobstructed (yes / partially blocked / blocked)
- Mounting height correct - handle 3.5-5 ft from floor (yes / too high / too low)
- Mounting bracket secure (yes / loose / damaged)
Blocked extinguishers are more common than missing ones. I've seen them hidden behind stacked boxes, holiday decorations, furniture. If you can't grab it in 3 seconds, it's blocked.
Physical Condition
- Cylinder condition (good / dented / corroded / damaged)
- Handle and lever (intact / damaged / missing parts)
- Hose and nozzle (good / cracked / clogged / missing)
- Safety pin and tamper seal (present and intact / broken / missing)
- Pressure gauge (in green zone / overcharged / undercharged / no gauge)
- Operating instructions label (legible / faded / missing)
- Inspection tag (present / missing)
Monthly Inspection Result
- Extinguisher passes monthly inspection (yes / no)
- Issues requiring attention (describe)
- Inspector name and date
- Inspection tag initialed and dated (yes / no)
Annual Maintenance Requirements
Annual maintenance goes beyond visual inspection. This must be performed by a certified technician. The checklist below documents that the annual service was completed.
Annual Service Documentation
- Annual maintenance performed by (company name)
- Technician name and certification number
- Service date
- Internal examination performed (yes / N/A based on type)
- Hydrostatic test due date checked
- Extinguishing agent verified (weight / pressure)
- All components inspected and functional
- New service tag attached (yes / no)
- Collar/verification of service installed (for applicable types)
6-Year Maintenance (Stored Pressure Extinguishers)
- 6-year maintenance due (yes / no)
- Internal examination performed
- Components replaced as needed
- New 6-year collar installed
Hydrostatic Testing (12-Year Requirement)
- Hydrostatic test due (yes / no)
- Test performed by (company name)
- Test date
- Test result (pass / fail / replaced)
- New hydro test label applied
NFPA 10 Compliance Summary
| Requirement | Frequency | Who Can Perform |
|---|---|---|
| Visual inspection | Monthly | Building staff |
| Maintenance | Annual | Certified technician |
| Internal examination | 6 years (stored pressure) | Certified technician |
| Hydrostatic test | 5-12 years (varies by type) | Certified facility |
Common Inspection Failures
Based on what I've seen in facility work:
Blocked access - The #1 issue. Storage creeps up around extinguishers. Make it someone's job to check monthly.
Missing tamper seals - Someone pulled the pin to see what would happen. If the seal is broken and the extinguisher wasn't used, it needs service.
Pressure in yellow/red zone - Slow leaks happen. If the gauge isn't in the green, it needs service.
Missing inspection tags - The tag is your proof of inspection. No tag = no documentation = failed inspection.
Expired hydrostatic test - Easy to miss if you're not tracking dates. An extinguisher past its hydro date is a liability.
Tracking Multiple Extinguishers
A small office might have 3 extinguishers. A commercial building might have 50+. A campus might have hundreds.
At scale, the challenge isn't doing the inspections - it's tracking them. Which units are due for annual service? Which need hydrostatic testing this year? Did unit #47 in the basement actually get inspected last month?
This is where digital tools help. Instead of paper inspection tags (which get lost, damaged, or forged), a mobile inspection app creates a permanent record tied to each extinguisher's serial number.
FormField can capture extinguisher data via camera - point at the label, AI reads the serial number and specs - then track inspection history over time. But any system that creates a searchable, auditable record is better than paper tags.
Use the Checklist
The checklist above is NFPA 10 compliant and field-tested. Adapt it for your specific requirements.
If you're managing a lot of extinguishers and want to automate the tracking, FormField's free trial lets you test the camera capture on your actual equipment.
