Monthly Fire Extinguisher Inspections: What NFPA 10 and OSHA Require, and the Records to Keep

Portable fire extinguishers are probably the most inspected thing in any building. A hospital, school or office tower can have hundreds of them, and every one needs a quick look every month.

The check itself takes less than a minute. Where facilities run into trouble is the paperwork: a missing month, a tag that disappeared when a unit was swapped, or no record of what happened to the one that failed. Here is what the rules ask for and how to keep records that hold up.

What the monthly inspection covers

NFPA 10, the Standard for Portable Fire Extinguishers, lists what a monthly inspection has to confirm. In plain terms:

  1. The extinguisher is in its designated place.
  2. It's visible, or there's signage showing where it is.
  3. Nothing is blocking access to it.
  4. The pressure gauge reads in the operable range.
  5. It's full, which you can check by lifting it or weighing it.
  6. On wheeled units, the tires, wheels, carriage, hose and nozzle are in good condition.
  7. On non-rechargeable units, the push-to-test pressure indicator works.

Most facilities also check that the pin and tamper seal are intact, the instructions face outward and are readable, and there's no obvious damage, corrosion, leakage or clogged nozzle.

How often

NFPA 10 requires an inspection when the extinguisher is first put in service. After that, the 2022 edition requires inspections at intervals of no more than 31 days, and at least once every calendar month. That rules out doing January on the 2nd and February on the 28th.

Extinguishers in places where they're more likely to be knocked around, rust or get tampered with should be checked more often. Weekly or even daily checks are appropriate there.

OSHA's rule for workplaces, 29 CFR 1910.157, says the same thing more briefly: portable extinguishers "shall be visually inspected monthly," and the employer is responsible for it.

Who can do it

Anyone knowledgeable and competent. NFPA notes that you don't need to be certified to perform the monthly inspection, so a facilities tech, a safety coordinator or a trained staff member can handle it.

Maintenance is different. The annual maintenance examination, internal examinations and hydrostatic testing have to be done by a certified technician, usually your fire protection contractor.

The records to keep

This is the part surveyors and fire marshals look at. Under NFPA 10:

Monthly inspection isn't annual maintenance

The monthly look doesn't replace the work your contractor does. NFPA 10 calls for an external maintenance examination every year. Internal examinations happen every one to six years, and hydrostatic tests every 5 or 12 years, depending on the type of extinguisher. A stored-pressure dry chemical extinguisher, the common ABC unit, needs an internal examination every 6 years.

OSHA lines up with this. It requires an annual maintenance check and a record of the annual maintenance date. Keep that record for one year after the last entry or for the life of the shell, whichever is less. Stored-pressure dry chemical units that need a 12-year hydrostatic test must also be emptied and maintained every 6 years.

When an extinguisher fails

Inspecting is only half the job; closing the loop is the other half. When an extinguisher fails the monthly check, write down what was wrong and get it serviced or replaced. Then record when it was fixed and by whom. Many facilities put a spare of the same type and rating in its place while the original is out.

An auditor will look for that whole sequence for every failure: the failure was found, someone owned it, and it was fixed.

Where paper tags fall short

A punched tag on the extinguisher is perfectly legal, and for a small building it works. As a building grows, the gaps show:

That's why NFPA 10 explicitly allows electronic records, and why more facilities are moving to them.

How RoundReady handles it

We built RoundReady for the teams that do these rounds. Each extinguisher gets a QR label. The tech scans it and the monthly checklist opens with the NFPA 10 reference attached. The tech marks each step, adds a photo if something's wrong and signs. The inspection is stamped with the date and the tech's name automatically, and it saves on the phone even in a basement with no signal.

When a step fails, RoundReady opens a corrective action with an owner and a due date. The action stays open until a passing re-inspection closes it. The schedule tracks when every extinguisher is due, so the manager sees what's coming up and what's overdue. When the fire marshal asks, one PDF shows every inspection, failure and fix for the date range they want. It works in English and Spanish.

RoundReady is free during launch, and we're looking for a facilities team to pilot it. Email support@articlex29.com with "RoundReady pilot" in the subject.

This guide summarizes general requirements and isn't legal advice. Your authority having jurisdiction enforces a specific edition of NFPA 10, sometimes with local amendments. Check that edition, and the manufacturer's manual, before you set your program.
