Do Fire Extinguishers Expire? Everything You Need to Know
小编2025-07-04
Yes — fire extinguishers do expire. While they may seem like durable, long-lasting equipment, extinguishers degrade over time and can eventually become unreliable. Whether you use a 1kg portable extinguisher or a 9kg industrial model, understanding their lifespan is critical to safety.
1. How Long Does a Fire Extinguisher Last?
Disposable (non-rechargeable) extinguishers usually last about 5 to 6 years.
Rechargeable models can last 10 years or more, but only with regular maintenance and servicing.
Always check the manufacturer’s label for the production or expiry date. If it’s been over 10 years, it’s time to replace it — even if it appears unused.
2. What Causes an Extinguisher to Expire?
Several factors affect lifespan:
Loss of internal pressure
Corrosion or rusting on the cylinder
Blocked or cracked hose/nozzle
Expired or leaking chemical agent
Over time, these issues can render the unit useless in a real fire emergency.
3. How to Check If It’s Still Safe to Use
Check the pressure gauge — the needle should be in the green zone
Inspect the body — no dents, rust, or leakage
Verify the tamper seal and safety pin
Look at the inspection tag — has it been serviced in the last year?
4. What If the Extinguisher Has Expired?
Don’t try to use or refill it. Expired extinguishers should be disposed of according to local hazardous waste regulations or returned to certified fire service companies for proper handling.
5. How to Stay Compliant
For home or business safety, create a fire extinguisher maintenance calendar. Make it a habit to inspect 1kg to 6kg units monthly and schedule annual checks for larger models like 9kg extinguishers.
A fire extinguisher that’s expired is not just useless — it’s dangerous. Don’t assume it will work when needed. Keep your protection up to date, and replace any unit that’s beyond its safe life span.
