Most fire extinguishers don’t expire. A rechargeable extinguisher has no expiration date: it stays in service as long as it keeps passing its inspections, maintenance and pressure tests. A disposable (non-rechargeable) extinguisher is different. It has to be replaced no later than 12 years after it was made, and right away after any use.
So “expired” usually means something else: a pressure gauge out of the green, a missed annual service, an overdue hydrostatic test, or a disposable unit past its 12 years. Here’s how long each type lasts, where to find its dates, and when to replace it.
Do fire extinguishers expire?
Not with a printed expiration date, but every extinguisher has dates that decide whether it can stay in service. NFPA 10, the national standard for portable fire extinguishers, sets a hard limit only for disposable units: they get no 6-year maintenance and no hydrostatic test, and come out of service at most 12 years after their manufacture date.
Rechargeable extinguishers have no fixed end date. Instead, OSHA requires employers to keep every extinguisher fully charged and working, give each one a maintenance check every year, and have its shell pressure-tested (a hydrostatic test) every 5 or 12 years depending on the type. An extinguisher that fails that test, or can no longer be serviced according to its manufacturer’s manual, has to come out of service for good.
How long do fire extinguishers last?
A disposable extinguisher lasts up to 12 years. A rechargeable one can last much longer, as long as it keeps passing its service and tests. The type decides how often it needs a hydrostatic test, and the test is what usually ends an old extinguisher’s life.
| Extinguisher type | How long it lasts | Service it needs |
|---|---|---|
| Disposable (non-rechargeable) dry chemical, including most home extinguishers | Up to 12 years from the manufacture date, and only until it’s used | Monthly checks; no 6-year maintenance and no hydrostatic test |
| Rechargeable stored-pressure dry chemical (ABC or BC) with a mild steel, brazed brass or aluminum shell | No set limit while it passes service and tests | Annual maintenance, emptied and serviced every 6 years, hydrostatic test every 12 years |
| Carbon dioxide (CO2) | No set limit while it passes service and tests | Annual maintenance, hydrostatic test every 5 years |
| Water, foam (including AFFF) and loaded stream | No set limit while it passes service and tests | Annual maintenance, hydrostatic test every 5 years |
| Wet chemical (Class K, for commercial kitchens) | No set limit while it passes service and tests | Annual maintenance, hydrostatic test every 5 years (NFPA 10) |
| Dry chemical with a stainless steel shell | No set limit while it passes service and tests | Annual maintenance, hydrostatic test every 5 years |
| Halon 1211 or 1301 | No set limit while it passes service and tests | Annual maintenance, hydrostatic test every 12 years |
Many home extinguishers are disposable: Kidde’s basic home models, for example, are built for 12 years of use with no internal service. The 6-year clock on a rechargeable dry chemical extinguisher restarts whenever it’s recharged or hydrostatically tested. For the monthly and annual checks in detail, see Brian’s guide to fire extinguisher inspection requirements.
Where is the expiration date on a fire extinguisher?
Look for the manufacture date, not an expiration date. Kidde, for example, prints it as a two-digit code on the bottom of the extinguisher or stamps a four-digit date into the cylinder. For a disposable extinguisher, add 12 years to that date to get the last day it can stay in service.
Rechargeable extinguishers carry two more dates. The service tag shows the last annual maintenance, and a hydrostatic test label or stamp shows when the shell was last tested, so you can work out when the next test is due. If you can’t find a date at all, ask a fire extinguisher service company to identify it, and treat the extinguisher as suspect until they do.
How to tell if a fire extinguisher is expired or needs replacing
Replace or service an extinguisher as soon as any of these is true:
- The gauge isn’t in the green. Kidde says an extinguisher is still good only if the needle is in the green (full) area and it was made less than 12 years ago.
- It’s been used, even briefly. NFPA 10 requires a rechargeable extinguisher to be recharged after any use, and disposable ones are marked to be discharged and thrown away after any use.
- It’s disposable and 12 years old, counting from the manufacture date.
- It’s damaged. New corrosion, dents or other damage call for a hydrostatic test under OSHA’s rule, and a shell that fails the test, or is too damaged to test, has to leave the workplace.
- It’s overdue for service: a missed annual maintenance, 6-year maintenance or hydrostatic test.
- It’s an obsolete type. NFPA 10 lists types that must be taken out of service, including any extinguisher you have to turn upside down to use, anything made before 1955, and stored-pressure dry chemical units with a manufacturing date of 1984 or earlier. OSHA doesn’t allow carbon tetrachloride or chlorobromomethane extinguishers in the workplace at all.
- It can’t be serviced anymore according to its manufacturer’s maintenance manual.
A monthly look catches most of these early. Our free fire extinguisher inspection checklist covers the gauge, the pin and tamper seal, access and visible damage, and the printable inspection tag records each check.
What to do with an expired fire extinguisher
A rechargeable extinguisher usually goes back to a service company; a disposable one gets replaced. At work, NFPA 10 says an extinguisher taken out of service must be replaced right away with one suited to the same hazard and rated at least as high, and OSHA requires equal protection to stay in place while extinguishers are out for maintenance or recharging.
To throw an old extinguisher away:
- Keep it out of the household trash. Kidde advises against it and points to local recycling and household hazardous waste programs, which take pressurized containers like extinguishers and propane tanks.
- Find a drop-off site through your city or county, or search Earth911.com, which Kidde recommends.
- Ask your local fire department. Some take old extinguishers, and they can tell you the rules where you are.
- Don’t empty a halon extinguisher. NFPA 10 says a disposable halon unit must not be discharged. Send it back to its maker or to a fire equipment dealer or distributor, who can recover the halon.
If you use a fire extinguisher service company, ask whether it takes old units when it delivers replacements.
How AED Log tracks fire extinguisher dates
AED Log keeps every extinguisher’s dates in one place, alongside your AEDs. Each extinguisher has a record with its class, capacity, serial or tag number, manufacture date and last service date. Its next service date and hydrostatic test due date show on the compliance calendar and raise an alert before they come due, by email or in Slack, Microsoft Teams or Discord.
The monthly checklist runs on any phone, with a QR code label on each extinguisher, and every inspection is saved with the date and the inspector’s name. If an extinguisher is used, the incident report records whether it now needs a recharge or a replacement. Fire extinguishers are an add-on at $6 per extinguisher per year, on top of an AED plan; see fire extinguisher inspection software. AEDs have a similar story: read how long an AED lasts.
Fire extinguisher expiration FAQ
How long is a fire extinguisher good for?
A disposable extinguisher is good for up to 12 years from its manufacture date, or until it’s used. A rechargeable one has no set limit: it stays in service as long as it passes its annual maintenance, 6-year maintenance where required, and hydrostatic tests.
Can you use an expired fire extinguisher?
Don’t count on one. A disposable extinguisher past 12 years, or any extinguisher overdue for service or with its gauge out of the green, should be replaced or serviced right away rather than left on the wall.
Do fire extinguishers go bad if they’re never used?
They can. That’s why each one gets a monthly look at its gauge and condition, a maintenance check every year and a hydrostatic test every 5 or 12 years, and why disposable units come out of service after 12 years even if unused.
Where is the manufacture date on a fire extinguisher?
Check the label and the cylinder. Kidde, for example, prints a two-digit code on the bottom of the extinguisher or stamps a four-digit date into the cylinder. Rechargeable units also carry a service tag and a hydrostatic test label.
How do you dispose of an old fire extinguisher?
Not in the household trash. Take it to a local recycling or household hazardous waste program, or ask your fire department. Never empty a halon extinguisher: return it to the maker or a fire equipment dealer.
Can AED Log track fire extinguisher service dates?
Yes. Each extinguisher’s next service and hydrostatic test due dates go on the calendar and raise an alert before they’re due, with monthly checks on any phone. It’s $6 per extinguisher per year on top of an AED plan.
