What fire extinguisher inspection involves

Fire extinguisher inspection is a set of checks on different cycles, and each one leaves a record.

Monthly inspection. A visual check that each extinguisher is in its designated place, unobstructed and visible, with the gauge in the operable range, fullness confirmed by weighing or lifting, the safety seal intact, no damage, corrosion, leakage or clogged nozzle, and legible instructions facing outward.
Annual maintenance. A thorough examination and any needed repair by a trained technician with the proper tools, listed parts and the manufacturer’s service manual. Rechargeable units receive a new tamper seal, and a service tag records the month and year, the technician and the company.
Six-year internal examination. Stored-pressure extinguishers that require a 12-year hydrostatic test are emptied and examined internally every 6 years, then recharged and fitted with a verification-of-service collar.
Hydrostatic testing. The cylinder is pressure tested by a trained technician with special equipment, at 5 or 12 year intervals depending on the type.

Fire extinguisher inspection requirements: codes and standards

Two sets of rules apply at most U.S. commercial sites: OSHA 29 CFR 1910.157, where extinguishers are provided for employee use, and NFPA 10, Standard for Portable Fire Extinguishers, which the fire code references (North Carolina, for example, through section 906.2 of its fire code). The edition in force varies, and the local fire code official decides which applies.

Responsibility. OSHA makes the employer responsible for inspection, maintenance and testing. NFPA 10 (2010 edition, 7.1.1) places it on the owner, not the service company.
Monthly. OSHA requires a monthly visual inspection (1910.157(e)(2)). NFPA 10 requires one at intervals of not more than 30 days and permits electronic monitoring as an alternative.
Annual. OSHA requires an annual maintenance check (1910.157(e)(3)). The North Carolina State Fire Marshal’s office has interpreted NFPA 10 (2013 edition, 7.1.2) to require that annual inspection and tagging be performed by certified personnel.
Six-year and hydrostatic. OSHA 1910.157(e)(4) and Table L-1 set the 6-year service and hydrostatic intervals: 5 years for water, foam, carbon dioxide and stainless steel dry chemical types, and 12 years for most stored-pressure dry chemical types. NFPA 10 (2010) adds a 5-year hydrostatic test for wet chemical (Class K) units and a 12-year service life for non-rechargeable extinguishers.
Out of service. When an extinguisher is removed for maintenance or recharge, OSHA requires alternate equivalent protection (1910.157(e)(5)).
Placement. OSHA sets a maximum travel distance of 75 feet to a Class A extinguisher and 50 feet from a Class B hazard. OSHA guidance sets a 30 foot maximum travel distance to a Class K extinguisher, and calls for the handle no higher than 5 feet for units up to 40 pounds, no higher than 3.5 feet for heavier units, and at least 4 inches of floor clearance.

Preventive maintenance schedule for fire extinguisher inspection

Extinguisher intervals are written into regulation. A planned schedule keeps every unit on its cycle, catches a low gauge or broken seal before an inspector does, and builds the record the fire marshal and insurer ask to see.

Task	Recommended frequency	Basis
Visual inspection of location, access, gauge, seal, condition and label	Monthly, not more than 30 days apart	OSHA 29 CFR 1910.157(e)(2); NFPA 10
Record date and inspector initials on tag, checklist or electronic record	Each monthly inspection	NFPA 10 (2010), 7.2.4
Annual maintenance, new tamper seal and service tag	Annually	OSHA 29 CFR 1910.157(e)(3); NFPA 10, 7.3
Empty and internally examine stored-pressure units requiring a 12-year hydrostatic test	Every 6 years	OSHA 29 CFR 1910.157(e)(4); NFPA 10 (2010), 7.3.1.2
Internal examination of carbon dioxide and wet chemical units	Every 5 years	NFPA 10 (2010), Table 7.3.1.1.2
Hydrostatic test of water, carbon dioxide, wet chemical and stainless steel dry chemical units	Every 5 years	OSHA Table L-1; NFPA 10 (2010), Table 8.3.1
Hydrostatic test of stored-pressure dry chemical units with mild steel, brazed brass or aluminum shells	Every 12 years	OSHA Table L-1; NFPA 10 (2010), Table 8.3.1
Remove non-rechargeable units from service	12 years from date of manufacture	NFPA 10 (2010), 7.3.1.2.1.3
Walk-through of extinguisher placement against the current floor plan	Quarterly and after any remodel or fixture reset	Facility First program default, adjusted per site
Employee education on extinguisher use	At hire and annually	OSHA 29 CFR 1910.157(g)

The authority having jurisdiction, the manufacturer and the property’s insurer can require more frequent service, and each location’s schedule is set in its program and recorded on every visit.

Signs an extinguisher needs service now

Gauge needle outside the operable range
Missing pin, broken tamper seal or missing tag
Dents, corrosion, leakage, a cracked hose or a clogged nozzle
Instructions worn off or facing the wall
Any discharge, even a short test squeeze
Unit missing from its bracket, or blocked by stock, fixtures or furniture

Under NFPA 10 (2010), a rechargeable unit with an out-of-range gauge goes to full maintenance, and a non-rechargeable dry chemical unit is removed from service.

Records to keep

Monthly inspection date and initials for each unit
Annual service tag showing month, year, technician and company
OSHA requires the annual maintenance date to be kept for one year after the last entry or the life of the shell, whichever is less
Six-year service label and verification-of-service collar
Hydrostatic test certification showing the test date, the tester’s signature and the extinguisher serial number, kept until the next test or until the unit leaves service
A service history per unit, which the Minnesota Department of Health recommends keeping for the life of the extinguisher

How Facility First runs fire extinguisher inspection across a portfolio

Inventory. Each location’s extinguishers are listed by type, rating and due dates, so 6-year and hydrostatic work is planned.
Schedule. Annual visits are booked by region. Monthly checks go to site staff or the provider, as the client chooses.
Dispatch. A vetted local provider holding the licenses and certifications the jurisdiction requires receives the work order.
Close-out. The technician photographs each new tag and reports deficiencies and replacements. Loaner units cover any unit taken off site.
Verification and invoice. Facility First checks the report against the inventory and invoices in one format. Records sit in PostControl for each location.

Corrective work within the client’s approval limits proceeds; anything above a limit is quoted first. See what NTE means.

Number of units per location
Extinguisher types and the internal examination and test cycle each one carries
How many units fall due for 6-year service or hydrostatic testing in the same year
Recharges after discharge, replacement parts and replacement units
Loaner units, cabinets, brackets and signage
Access windows, after-hours visits and travel to remote sites

Fire extinguisher inspection for retail stores, restaurants and offices

Retail stores. Fixture resets, seasonal displays and deliveries often leave extinguishers blocked or hidden. Service is scheduled outside trading hours, and placement is rechecked after every remodel. Shopping center leases can add landlord inspection and certificate requirements.

Restaurants. Kitchens with cooking oils and fats need a Class K extinguisher, which OSHA guidance places within 30 feet of travel distance. Wet chemical units carry 5-year internal examination and hydrostatic cycles, and service is coordinated with the kitchen hood suppression and fire protection work at the same site to limit downtime.

Offices. In multi-tenant buildings, the lease decides whether the landlord or the tenant owns the extinguishers in a suite. Where paper, furniture and other Class A materials dominate, OSHA limits travel distance to 75 feet, and the fire code official confirms the number and rating of units for the suite.

Frequently asked questions

How often should fire extinguishers be inspected?

A visual inspection is required monthly, at intervals of not more than 30 days, and a full maintenance check annually. Longer cycles apply for 6-year internal examination and 5 or 12 year hydrostatic testing, and local code can add requirements.

Can store staff do the monthly inspection?

Yes. NFPA 10 treats the monthly check as a visual inspection that facility staff may perform, provided the date and initials are recorded. Annual maintenance requires a trained technician, and some states require certification.

Which records does a fire inspector ask for?

Usually the current annual tag on each unit, the monthly inspection record and proof of 6-year and hydrostatic service where due. Facility First keeps these per location.

Is fire extinguisher inspection required in a small office?

Where extinguishers are provided for employee use, OSHA requires monthly inspection and annual maintenance. OSHA exempts employers whose written policy is immediate total evacuation and who provide no extinguishers, but the local fire code can still require extinguishers.
