A fire extinguisher that isn’t working is one of the most dangerous hidden risks in a home. You may never need to use it — but if you do, it must work instantly. Fortunately, inspecting a fire extinguisher is simple and only takes a few minutes.
Here’s how to check whether your fire extinguisher is ready for an emergency and what to do if it’s not.
—
1. Check the Pressure Gauge
Every fire extinguisher has a pressure gauge that shows whether it’s ready for use.
What to look for:
- Needle in the green zone = ready
- Needle in the red zone = under‑pressurized or over‑pressurized
- No movement or broken gauge = replace immediately

2. Inspect the Safety Pin and Tamper Seal
The safety pin prevents accidental discharge.
What to check:
- Pin is fully inserted
- Tamper seal is intact
- No signs of tampering or damage
If the pin is missing or loose, the extinguisher may not work properly.

3. Look for Physical Damage
A damaged extinguisher is unsafe to use.
Warning signs:
- Dents or cracks
- Rust or corrosion
- Leaking powder or residue
- Loose or broken handle
If you see any of these, replace the extinguisher immediately.

4. Check the Hose and Nozzle
A clogged or cracked hose can prevent the extinguisher from discharging.
What to inspect:
- Hose is flexible, not brittle
- No cracks or holes
- No obstructions in the nozzle
Dust buildup can also affect other home fixtures.

5. Verify the Expiration Date
Fire extinguishers don’t last forever.
Typical lifespan:
- Disposable extinguishers: 10–12 years
- Rechargeable extinguishers: 6 years between services
If yours is expired, replace it — even if it looks fine.

6. Shake Dry Chemical Extinguishers (If Applicable)
Some dry chemical extinguishers can compact over time.
What to do:
- Turn the extinguisher upside down
- Gently shake to loosen the powder
- Do this once or twice a year
Check your model’s instructions before doing this.

7. Make Sure It’s Stored Correctly
Improper storage can damage the extinguisher or make it hard to access.
Best practices:
- Mount it on a wall or keep it upright
- Store in a cool, dry place
- Keep it visible and easy to reach

8. Know When to Replace the Extinguisher
Replace your fire extinguisher if:
- It’s expired
- The gauge is in the red
- The pin or seal is missing

Fire extinguishers are inexpensive — replacing them is the safest choice.

Call a fire safety professional if:
- You’re unsure whether the extinguisher is safe

- You have multiple extinguishers to service
Professionals can test, recharge, and certify extinguishers.
