TL;DR - Key Takeaways
- • Monthly: Visual only, anyone can do it, 30 seconds, tag initial + date - NFPA 10 §7.2
- • Annual: Full hands-on, certified tech required, 2-5 minutes, full maintenance tag - NFPA 10 §7.3
- • Both may be relevant: Map monthly and annual activities to the adopted edition, site, equipment, and AHJ direction; neither this page nor the software determines what is required
Monthly vs Annual Fire Extinguisher Inspections (NFPA 10)
Understanding the difference between monthly and annual fire extinguisher inspections is critical for building owners, facility managers, and fire protection contractors. They serve different purposes, are performed by different people, and have different legal weight. Here's everything you need to know.
In this guide
Side-by-Side: Monthly vs Annual
| Factor | Monthly Inspection | Annual Inspection |
|---|---|---|
| NFPA 10 reference | §7.2 | §7.3 |
| Frequency | Every 30 days | Every 12 months |
| Who performs it | Building owner, staff, or designated employee — no certification required | Certified fire extinguisher technician — certification required |
| What's checked | Location, accessibility, gauge, tamper seal, physical damage, legibility of label | All monthly checks PLUS weight verification, hose/nozzle inspection, hydro date check, bracket security, hazard class match |
| Extinguisher off wall? | No — stays mounted | Yes — removed for full hands-on inspection |
| Time per extinguisher | 30 seconds — 1 minute | 2–5 minutes per extinguisher |
| Documentation | Initials and date on tag, or electronic log entry | Complete annual maintenance tag: date, company name, technician ID, extinguisher info |
| Possible review | An AHJ may ask for monthly records depending on the site and process | An AHJ, customer, or insurer may ask for annual evidence depending on the applicable requirements |
| Insurance relevance | Depends on the policy and facts | Depends on the policy, facts, and records requested |
| If missed | Review the gap against current requirements | Obtain qualified advice on the applicable corrective action |
Monthly Visual Inspection — In Detail
Who does it: Building owner, maintenance staff, or a designated employee. No certification is required. This is a DIY inspection that anyone can perform with basic training.
The 7-point monthly checklist (NFPA 10 §7.2):
- Location check: Is the extinguisher in its designated place? Has it been moved?
- Access check: Is the path to the extinguisher clear? No boxes, furniture, or equipment blocking it?
- Gauge check: Is the pressure needle in the green (operable) zone? For CO2 extinguishers (no gauge), check the weight by gently lifting.
- Tamper seal: Is the safety pin in place? Is the tamper seal intact? If the seal is broken, the extinguisher may have been partially discharged or tampered with.
- Physical damage: Any dents, rust, corrosion, or chemical residue on the cylinder? Is the nozzle clogged or cracked?
- Label legibility: Can you read the operating instructions on the nameplate? Is it facing outward?
- Mounting bracket: Is the bracket secure to the wall? No loose screws or sagging?
How to document: Record your initials and the date on the paper tag attached to the extinguisher, or log it electronically. If using a paper tag template, our free printable inspection tags include space for 12 monthly entries plus the annual record.
Who can do monthly inspections? The building owner, a designated maintenance employee, or any trained staff member. You do not need a fire extinguisher certification to perform a monthly visual inspection. It is a visual walk-by check, not a hands-on technical inspection.
Annual Maintenance Inspection — In Detail
Who does it: Only a certified fire extinguisher technician. This is where your fire protection company adds value — the annual inspection requires technical knowledge, certification, and proper documentation.
The annual maintenance checklist (NFPA 10 §7.3):
- All monthly checks (7-point visual inspection, listed above)
- Remove from bracket: Remove the extinguisher from its wall bracket or cabinet for full hands-on examination
- Weight verification: Weigh the extinguisher and compare against the stamped weight on the nameplate. Any loss over 10% requires recharging
- Date of manufacture check: Confirm the extinguisher is within its service life and determine 6-year and 12-year service windows
- Hydrostatic test date: Check the last hydro date stamped on the cylinder. CO2: ≤5 years. Dry chemical: ≤12 years. If expired, the extinguisher must be removed from service immediately
- Hose and nozzle: Inspect for cracks, dry rot, blockages, or damage. Remove any debris from the nozzle opening
- Valve and discharge lever: Verify smooth operation, no sticking or corrosion on the valve stem
- Hazard class match: Confirm the extinguisher type (ABC, CO2, Class K, etc.) matches the fire hazards in the protected area per NFPA 10 §5.4
- Mounting bracket condition: Verify bracket is secure, corrosion-free, at the correct height (top ≤5 ft for ≤40 lb units, top ≤3.5 ft for >40 lb units)
- New tag: Attach a new annual maintenance tag with company name, technician ID, date of service, extinguisher type, and next service due date
An annual maintenance tag may be one record a reviewer requests. Its meaning depends on the adopted requirements, site, and facts; do not infer an automatic compliance or insurance outcome from its presence or absence.
Legal and Insurance Implications
Monthly inspections: Responsibility depends on the workplace, contract, jurisdiction, and adopted requirements. Keep an accurate record and obtain professional advice rather than assuming who carries legal responsibility.
Annual inspections: Qualification, licensing, scope, and responsibility depend on the jurisdiction and service agreement. This page cannot allocate liability or predict an insurance outcome; have counsel or a fire-protection professional review the arrangement.
Important: Annual does not replace monthly
Do not assume one activity replaces another. Confirm the relationship between monthly, annual, and other work with the current adopted requirements and local AHJ.
What Each Inspection Costs
For building owners budgeting fire extinguisher maintenance, and for contractors setting their rates:
| Inspection Type | Typical Rate (Per Unit) | Typical Visit Minimum | Who Pays |
|---|---|---|---|
| Monthly visual | $3–$10/extinguisher | $50–$150 | Building owner (or in-house) |
| Annual maintenance | $15–$40/extinguisher | $100–$250 | Building owner (hires contractor) |

Documentation Requirements Compared
Monthly documentation is minimal — initials and a date. Annual documentation is comprehensive and must include, per NFPA 10 §7.3.3:
- Month and year the maintenance was performed
- Name of the person or company performing the work
- Identification of the extinguisher serviced (location, type, or serial number)
Digital documentation may help organize observations and evidence. FireInspected's early beta does not promise a complete record, all required fields, AHJ acceptance, insurance acceptance, or electronic filing in any jurisdiction.
How FireInspected handles both inspection types
FireInspected includes separate workflows optimized for each inspection type:
- Monthly form: 7 quick fields, 30-second completion on your phone, auto-logged with date and technician. Perfect for building owners or technician route inspections.
- Annual form: Research-based fields for observations such as weight, hydro date, hazard context, bracket condition, and notes. Review the final record against the adopted requirements before sharing it.
