Many fire extinguishers don't have an "expires on" date. You check three things instead: the gauge, the date it was made, and if it's disposable or rechargeable. Fire extinguisher expiration comes down to this: a disposable one gets replaced 12 years after it was made, or after any use. A rechargeable one gets an internal check every 6 years and a pressure test at 12.
I checked mine for a Reel in my "Things no one taught you" series. It takes two minutes. Here's the whole check, and what to do with an old one.
Needle in the green: it's charged. The gauge can't tell you how old it is.
How do you read a fire extinguisher gauge?
Look at the needle. Green means it holds enough pressure to work. Left of green means it's low and needs a recharge or a replacement. Right of green means it's overcharged.
A green needle is only half the answer. Kidde, which makes extinguishers, says yours is good when the needle is in the green and it was made less than 12 years ago. The gauge reads pressure. It knows nothing about age.
While it's in your hand, give it a once-over. Check for 1. the gauge in range, 1. nothing blocking it, 3. seals intact, 3. no damage, rust, leaks or clogged nozzle.
Where is the date on a fire extinguisher?
Turn it over. Pye-Barker Fire & Safety says to look on the label or the bottom of the cylinder. Serviced Fire Equipment adds the cylinder neck. On mine, it's a printed code on the bottom.
Every brand writes it differently. Some print a plain year. Some print a code. If you can't read yours, look up the model number on the maker's website or call them. Don't guess.
Is your extinguisher disposable or rechargeable?
Read the label first. Serviced Fire Equipment says a unit marked "Non-Rechargeable" or "Discard After Use" is disposable.
The head is a clue. Pye-Barker says a rechargeable unit usually has a metal head, and a disposable one a plastic head. Mine doesn't fit that rule neatly, which is why the label wins.
Read the whole label. It tells you the type and what fires it's rated for.
How long does a fire extinguisher last?
NFPA 10 is written for businesses, but it's the clearest rulebook there is. Per the Minnesota Department of Health's summary of it:
Disposable: out of service 12 years from the date it was made. Serviced Fire Equipment adds: replace it after any discharge, even a short one.
Rechargeable (dry chemical): emptied and checked inside every 6 years, and pressure-tested every 12. A fire equipment company does both.
Any type: if the gauge is out of the green, it's dented or rusted, or the seal is broken, take it out of service.
Should you recharge it or replace it?
For a small home unit, replacing is often the simpler call. ThePricer puts a recharge for a small home extinguisher at about $20 to $60, and a new one at about $25 to $60. A disposable can't be recharged at all.
How do you get rid of an old fire extinguisher?
Not in the trash or the recycling bin. Home Depot's guide says extinguishers hold chemicals that aren't safe in either, and points you to:
household hazardous waste site
your fire department or city hall.
A fire equipment company: if you're buying or servicing one, ask if they'll take the old one.
Who keeps track of this in your house?
A fire extinguisher is easy to forget. It sits in a cabinet for years and works only if someone checked it. Same with a smart water shutoff valve: safety gear is only as good as the last time someone looked at it.
At Home CEO Services, that's our job. Nothing to remember. We track every system, maintenance date, and warranty for the homes we manage in Brentwood, Franklin, Nashville and across Williamson County.
Frequently asked questions
Do fire extinguishers expire?
Many don't print an expiration date, but they don't last forever. Per NFPA 10, a disposable unit comes out of service 12 years after it was made. A rechargeable one needs service every 6 years and a pressure test at 12.
Is my extinguisher OK if the gauge is green?
Only if it's also less than 12 years old, per Kidde. The gauge shows pressure, not age, so check the date too.
Can I throw away a fire extinguisher?
Not in the trash or recycling. Take it to a household hazardous waste collection, or call your fire department or city hall to ask where it goes.
Do I need a new extinguisher after using it once?
Yes, for a disposable one, per Serviced Fire Equipment. A rechargeable one needs a recharge from a fire equipment company before you count on it again.
