How Often Should You Replace a Fire Extinguisher?
Many home fire extinguishers should be replaced after 12 years or after use, but gauge, type, damage, and service status matter too.
Many common home fire extinguishers should be replaced when they are more than 12 years old or after they have been used. Replace or service one sooner if the gauge is not in the green, the pin or seal is missing, the hose is cracked, the can is dented or corroded, or the extinguisher is recalled.

Type changes the answer
Disposable and rechargeable extinguishers do not always follow the same path. A disposable unit is usually replaced, while a rechargeable unit may be professionally serviced if it is otherwise within its service requirements.

- 4Replace or service the extinguisher after any use.

FAQ
Do fire extinguishers expire after 12 years?
Many common disposable home extinguishers use a 12-year replacement rule, but rechargeable units and commercial extinguishers may need inspection, service, or hydrostatic testing instead.
Should I replace a fire extinguisher after one use?
Yes, treat a used extinguisher as needing service or replacement right away. Even a short discharge can lower pressure or leave it unreliable for the next emergency.
What if the gauge is still in the green?
A green gauge is necessary but not the whole check. Also verify the manufacture date, damage, corrosion, hose condition, recall status, and whether the extinguisher has ever been used.
