Fire extinguishers last between five and 15 years but they all ultimately expire and become ineffective, no matter what fire-fighting substance they contain.
The exception to this is CO2 extinguishers, which require refurbishing rather than refilling and should be refurbished 10 years after manufacturing. In some areas, the fire code laws may require businesses to have their extinguishers serviced annually to ensure they function properly. Check your local regulations.
How Long Does a Fire Extinguisher Last? – State Systems
Lifespan of a Fire Extinguisher. When you purchase a new carbon dioxide, pressurized water, or wet chemical extinguisher, you can expect it to last at least five years. For dry chemical extinguishers, the minimum lifespan is 12 years.
CO 2 fire extinguishers should be replaced every 10 years. But obviously, there are caveats. Fire extinguishers need to have been maintained in good working order. That includes both the monthly visual checks and the annual fire extinguisher inspection by a competent fire extinguisher engineer (more on that below).

How do I know if my fire extinguisher is working properly?
If the needle is within the green area, your extinguisher should be in working order. If so, set up a monthly reminder on your calendar or your phone to continue checking the gauge. A needle in the red or white area indicates that it requires service.
What happens if you throw a fire extinguisher in the trash?
Never throw a fire extinguisher into the trash or recycling bin, because it still has hazardous, pressurized chemicals inside that can contaminate the earth or even explode. Depending on where you live, improper fire extinguisher disposal may also be subject to a fine.
