Fire Extinguisher Inspection Requirements: Monthly and Annual

Fire extinguisher inspection requirements come from more than one place. Federal OSHA sets a monthly and an annual duty for portable extinguishers in general industry, your local fire code adds its own rules, and NFPA 10 is the standard most service companies and fire marshals refer to. This guide starts with the federal rule, then covers how the checks are done in practice and how to keep a simple record.

What federal fire extinguisher inspection requirements say

Federal fire extinguisher inspection requirements for general industry are in 29 CFR 1910.157, paragraph (e). Two lines set the inspection schedule.

• 29 CFR 1910.157(e)(2): portable extinguishers shall be visually inspected monthly.
• 29 CFR 1910.157(e)(3): the employer makes sure portable extinguishers get an annual maintenance check. The employer records the annual maintenance date and keeps that record for one year after the last entry or the life of the shell, whichever is less.

That is the core. The rule does not give a list of items for the monthly check, and it does not say the monthly check must be written down. It does say the annual maintenance date must be recorded and kept.

The same section has more detail on hydrostatic testing and on extinguishers that are emptied for maintenance at longer intervals. Those intervals depend on the extinguisher type, and your service company reads them from the label and the service tag.

How often the fire extinguisher inspection requirements apply

Fire extinguisher inspection requirements run on two clocks: every month for the visual check, and every year for maintenance. Longer-interval service comes on top of that for some types.

The monthly check can fall on any day in the month. Many sites pick a fixed day, such as the first Monday, so it does not get skipped. A gap of one month is easy to see in a log and hard to explain later.

Who can do the monthly fire extinguisher check

The monthly fire extinguisher check does not need a license under the federal rule. The rule puts the duty on the employer, and the employer can assign it to someone on site. Facility managers, office managers, maintenance staff, and safety coordinators commonly do it.

Whoever does it should be shown what a normal extinguisher looks like: where the gauge needle should sit, what the pin and tamper seal look like, and where the tag is. Ten minutes with the service company on their annual visit is a good way to train a new person.

The annual maintenance check is different. It involves a closer look at the mechanical parts and sometimes recharging, so most workplaces hire a fire extinguisher service company. Some states and cities license the companies and technicians who do this work. Check with your local fire marshal if you are not sure.

What to check in a monthly fire extinguisher inspection

A monthly fire extinguisher inspection is a quick look, usually under a minute per unit. Common checks, which match the five columns in the template's monthly log:

1. In place, visible, and not blocked. The extinguisher is on its hanger or in its cabinet, the sign is visible, and nothing is stacked in front of it.
2. Gauge in the operable range. On stored pressure units, the needle is in the green. Some units, such as CO2 extinguishers, have no gauge; follow the label, which may call for a weight check.
3. Pin and tamper seal intact. A broken seal can mean someone used it or tampered with it.
4. No damage, rust, or leaks, and the hose and nozzle are clear. Look for dents, corrosion, a cracked hose, or a nozzle with a nest or debris in it.
5. Tag present and current. The service tag shows the last annual maintenance date. If it is more than a year old, call the service company.

The label on each extinguisher lists the checks for that model. If the label asks for something extra, such as turning a dry chemical unit upside down, add it to your routine.

What happens when an extinguisher fails a check

Fire extinguisher inspection requirements do not end at finding the problem. Some failures can be fixed on the spot, and some mean the unit has to go out for service.

Fix on the spot:

• Something is blocking the extinguisher. Move it and tell the area lead.
• The sign is missing or hidden. Replace or move it.
• The extinguisher is off its hanger. Put it back.

Take it out of service:

• The gauge is out of range.
• The pin is missing or the seal is broken and you cannot confirm it was not used.
• The shell is dented, corroded, or leaking, or the hose is cracked.
• The extinguisher was used, even for a moment. A partly discharged unit may not work the next time.

When a unit goes out for service, put a spare of the same type in its place until it comes back. Write down what was done, the date, and when the unit came back. That line is the proof that the problem was closed.

Fire extinguisher inspection requirements for records and tags

Fire extinguisher inspection requirements for records are narrower than many people think. Under 1910.157(e)(3), the employer records the annual maintenance date and keeps that record for one year after the last entry or the life of the shell, whichever is less. The record must be available to OSHA on request.

For the monthly check, the federal rule is silent on records. Two common ways to show it was done:

• Initial and date the back of the service tag each month. NFPA 10 is commonly referenced for this practice, and many local fire codes follow it. The weak point is that one missed month on one tag is easy to overlook, and an inspector may treat a blank as a missed check.
• Keep a log with one line per extinguisher per month. A log shows every unit in one place, so you can see which ones are due without walking the building.

Many sites do both: initials on the tag for the fire marshal walking the building, and a log for the manager who needs to see the whole picture. The Fire Extinguisher Inspection Log has two sheets for this. The Extinguisher Register lists every unit with its location, type, size, manufacture year, annual maintenance date, and service company, and calculates the next annual date 12 months out. The Monthly Inspection Log has the five checks per unit, a result, the action taken, initials, and the next due date. It is a way to record the checks; it is not an official OSHA or fire department form.

Local fire codes, NFPA 10, and state plans

Fire extinguisher inspection requirements at your site may be stricter than the federal rule. Three sources commonly add to it:

• Local fire codes. Your city or county fire marshal enforces the fire code adopted where you are. It often adopts NFPA 10 by reference, sets who may service extinguishers, and sets what the tag must show.
• NFPA 10. This is the standard commonly referenced for selecting, placing, inspecting, and maintaining portable extinguishers. It is not a federal OSHA rule by itself, but your fire code may make parts of it binding.
• State plans. States that run their own OSHA program, such as California and Washington, may add requirements.

Your insurer may also ask for specific records. When the rules differ, follow the strictest one that applies to your building. The monthly check also fits well into a wider walk-through; the workplace safety inspection checklist and the facility inspection checklist both have room for exits, signs, and extinguisher locations.

Setting up a monthly routine that does not slip

A monthly routine is the part of fire extinguisher inspection requirements that most often breaks down, simply because a month goes by fast. A few habits help:

1. Number every extinguisher and put the number on its wall sign, so the log and the unit match.
2. Walk the same route each month, floor by floor, in the order the register lists them.
3. Set a calendar reminder for the same day each month, with a backup person named.
4. After the annual visit, update the register the same day and file the service company's report with it.
5. Start a new log each year and copy the register over, so the annual dates carry forward.

A maintenance schedule template is useful if extinguishers are one of many recurring tasks in your building, such as emergency lights or generator tests.

Fire extinguisher inspection requirements FAQ

Fire extinguisher inspection requirements raise a handful of questions that come up at almost every site.

How often do fire extinguishers need to be inspected?

Under 29 CFR 1910.157(e)(2), portable extinguishers are visually inspected monthly. Under 1910.157(e)(3), they also get an annual maintenance check. Some types need internal maintenance or a hydrostatic test at longer intervals, which your service company tracks.

Can I inspect my own fire extinguishers?

For the monthly visual check, yes. The federal rule does not require a license for it, and the employer can assign a trained employee. The annual maintenance check is usually done by a service company, and some states and cities require it to be done by a licensed company.

How long do I need to keep fire extinguisher inspection records?

For the annual maintenance date, 1910.157(e)(3) says the record is kept for one year after the last entry or the life of the shell, whichever is less. The federal rule does not set a record or retention period for the monthly checks. Your fire code or insurer may ask for more.

What does the monthly inspection tag need to show?

The federal rule does not say what goes on the tag. NFPA 10 is commonly referenced for noting the date and the initials of the person who did the check, and many local fire codes follow it. Ask your fire marshal what they expect to see.

Do the OSHA rules apply to construction sites?

The paragraphs above are in the general industry standard. Construction work has its own fire protection rules, and the monthly and annual pattern described here is common on job sites too. Check the rules that apply to your work.
