Fire extinguishers last between five and 15 years but they all ultimately expire and become ineffective, no matter what fire-fighting substance they contain.
Fire extinguishers have an average life expectancy of approximately 5-12 years. The manufacture date will tell you the age of the fire extinguisher and you can find it on the fire extinguisher’s UL nameplate. Even if a fire extinguisher is less than 10 years old, it still requires some maintenance and may have small amounts of sustained damage.
Do Fire Extinguishers Expire? How Long Do They Last?
Yes, most fire extinguishers will last for 5 to 15 years and they usually indicate the lifespan of the extinguisher. Though they may last for years, they need to be inspected and serviced/recharged regularly (usually annually) to function properly.
The exact shelf life of every fire extinguisher varies from manufacturer to manufacturer and whether it is rechargeable or disposable. According to the National Fire Protection Association (NFPA) standards, rechargeable fire extinguishers must be recharged every 6 years, whereas disposable extinguishers must be replaced every 12 years.

How long do fire extinguishers last?
It may surprise you that fire extinguishers will not last forever. A fire extinguisher is no longer “good” when the chemicals within the extinguisher lose their charge, or when the pressure of the contents has fallen.
Do fire extinguishers lose charge over time?
Household fire extinguishers—which are typically filled with dry chemicals (carbon dioxide or halon)—lose their charge over time. Those with compressed gas can leak contents slowly as their seals weaken, while those with ammonium phosphate will solidify over the years, rendering the entire device unusable.
What to do if your fire extinguisher is expired?
If the canister is dented or bruised, or if the tamper seal and pin are missing, there’s a possibility that it might explode unprompted. Examine the entire unit and if it’s not in good shape, properly dispose of it without delay. If your fire extinguisher is indeed expired or damaged beyond repair, dispose of it properly.
How can you tell if a fire extinguisher is rechargeable?
You can tell the difference between the two by the head; a rechargeable extinguisher has a metalhead with a gauge that reads Charge/Recharge, and a disposable extinguisher has a plastic head with a gauge that reads Full/Empty. How do you know if a fire extinguisher is still good?
