Fire Extinguisher Inspection Checklist

What a fire extinguisher inspection checklist is for

A fire extinguisher inspection checklist is the record of the monthly visual check OSHA expects on portable extinguishers in general-industry workplaces. The federal standard is 29 CFR 1910.157, Portable fire extinguishers. Employers must keep units fully charged, operable, and in their designated places — and they must inspect, maintain, and test them on a set schedule.

Paper tags with faded initials are still common in restaurants, warehouses, and small facilities. They are easy to skip and hard to produce during an OSHA visit. This checklist gives your team a one-page log they can finish this month. FireTag AI is the same workflow with QR scans, photos, and AI verification of the gauge and seal.

OSHA monthly vs. annual inspection requirements

OSHA does not treat “inspection” as one event. 1910.157(e) and (f) split the program into a monthly visual inspection the employer can assign to trained staff, an annual maintenance check, periodic internal maintenance, and hydrostatic testing of the cylinder.

The PDF you download is built for the monthly visual inspection. It also leaves space to note the last annual service and hydrostatic test so those dates do not drift off a hanging tag.

Monthly visual inspection (29 CFR 1910.157(e)(2))

OSHA requires portable extinguishers — or hose used in lieu of them — to be visually inspected monthly. The employer is responsible for that inspection. In practice, a designated employee walks each unit and confirms it is still in place, accessible, unactuated, and free of obvious damage.

Industry practice, including NFPA 10 monthly visual checks, fills in the points most safety managers put on a fire extinguisher inspection checklist:

1. 01Designated location

   The extinguisher is in its assigned place, visible, and identified so employees can find it without delay.

2. 02Clear access

   Nothing blocks the unit — no pallets, extra chairs, or storage in front of the cabinet or hook.

3. 03Nameplate and instructions

   Operating instructions are legible and facing outward. The classification (A, B, C, K, etc.) is readable.

4. 04Pin and tamper seal

   The safety pin is seated and the seal or indicator is intact. A missing seal can mean the unit was used or tampered with.

5. 05Pressure gauge

   On stored-pressure units, the needle is in the operable (typically green) range — not overcharged and not in recharge.

6. 06Physical condition

   No dents, corrosion, leakage, clogged nozzle, cracked hose, or other obvious damage that would prevent operation.

7. 07Mounting and charge

   The hanger, bracket, or cabinet is secure. The extinguisher feels fully charged when lifted, if that check applies to the type.

How to complete this checklist each month

Print the PDF, or keep a copy at the kitchen office, warehouse desk, or facility shop. Work one extinguisher at a time so a missed unit does not hide in a batch of initials.

1. 1

   Walk the designated locations

   Start from your facility map or asset list. Confirm every portable extinguisher is in its designated place and visible.

2. 2

   Check access and identification

   Make sure the path to each unit is unobstructed and that the signage or cabinet still identifies it for employees.

3. 3

   Inspect the gauge, pin, and seal

   Verify the pressure indicator is in the operable range and that the tamper seal and safety pin are intact.

4. 4

   Look for damage or discharge

   Examine the cylinder, hose, nozzle, and nameplate for corrosion, leaks, dents, clogging, or a discharged appearance.

5. 5

   Record the inspection

   Log the date, inspector name, unit ID, and pass/fail on this fire extinguisher inspection checklist. Tag failed units out of service.

6. 6

   Correct or replace failures immediately

   OSHA requires extinguishers to be maintained fully charged and operable. Swap in a spare if you remove a unit for service.

Annual maintenance (29 CFR 1910.157(e)(3))

OSHA requires portable fire extinguishers to receive an annual maintenance check. Stored-pressure extinguishers do not require an internal examination as part of that annual check. The employer must record the annual maintenance date and retain the record for one year after the last entry or the life of the shell, whichever is less, and make it available to OSHA on request.

This is not the same as the monthly visual walk. Annual maintenance is a thorough examination of mechanical parts, extinguishing agent, and expelling means, and it is normally performed by a licensed fire-protection contractor. Do not treat a completed monthly checklist as a substitute for that service.

Stored-pressure dry chemical extinguishers that require a 12-year hydrostatic test must also be emptied and given applicable maintenance every six years, unless they use non-refillable disposable containers (1910.157(e)(4)). When a unit is removed for maintenance or recharge, OSHA requires alternate equivalent protection in its place (1910.157(e)(5)).

Hydrostatic testing (29 CFR 1910.157(f))

Cylinders must be hydrostatically tested at the intervals in OSHA Table L-1 by trained persons with suitable equipment. Common intervals: 5 years for water, AFFF, foam, and carbon dioxide extinguishers; 12 years for many stored-pressure dry chemical and Halon units. Evidence of the test is a certification record with the test date, the tester’s signature, and the extinguisher serial number or other identifier. Keep that record until the next test or until the unit is taken out of service.

Units that fail a hydrostatic test, or that are not fit for testing, must be removed from the workplace. Note the last hydro date on each asset so monthly inspectors can flag a unit that is overdue before the annual vendor visit.

Recordkeeping that holds up in an inspection

OSHA’s annual-maintenance record rule is explicit. For monthly visual inspections, employers still need a record they can show: the date, who inspected, which extinguisher, and the result. Initials on a tag can meet that need if they are actually completed every month. A dated fire extinguisher inspection checklist — or a digital log with photos — is easier to produce when an OSHA compliance officer, insurer, or authority having jurisdiction asks.

If a unit fails, remove it from service, provide a spare if employees still rely on extinguishers, and open a work order with your fire-protection vendor. Do not return a failed unit until it is serviced.

When a paper checklist is no longer enough

A PDF is the right first step for a single kitchen or a small warehouse. It breaks down when you have multiple locations, rotating staff, or a manager who cannot prove last month’s round happened. FireTag AI assigns the monthly walk, timestamps each QR scan, uses AI to verify the pressure gauge and tamper seal, and exports an OSHA-aligned report after the round is finished.
