How Often Should Fire Extinguishers Be Checked?
Last updated October 25, 2026
The short answer
Monthly Checks
You can do a simple monthly check in under a minute. Look at the pressure gauge to confirm the needle is in the green zone. Ensure the safety pin is intact and the tamper seal is not broken. Check for any dents, rust, or leakage on the body and nozzle.
If you spot any issues, replace the extinguisher or have it serviced by a professional. Monthly checks are about catching small problems before they become big ones. Keeping a written log of your checks can help you remember what you inspected and when.
Also, make sure the extinguisher is easily accessible and not blocked by boxes, furniture, or other items. In an emergency, you don't want to waste time moving things to reach it. Keep your extinguisher in a spot that is easy to grab, like near a kitchen exit or garage door.
Annual Professional Inspection
Once a year, have a qualified professional inspect your fire extinguisher. This is a more thorough check that includes verifying the internal pressure, checking the hose and nozzle for blockages, and confirming the extinguisher is properly charged. The professional will also look for any signs of corrosion or damage that you might have missed.
This annual service is separate from a monthly visual check. The cost of this service is not fixed; it often depends on the type and size of your extinguisher, as well as the service provider's rates. However, it is a worthwhile investment to ensure your extinguisher works when you need it most.
Hydrostatic Testing
Hydrostatic testing is a more rigorous procedure that checks the integrity of the extinguisher's cylinder. This test involves filling the extinguisher with water or another fluid and pressurizing it to ensure it doesn't leak or rupture. This is not something you can do yourself; it requires specialized equipment and training.
The frequency of hydrostatic testing depends on the type of extinguisher. For example, a standard dry chemical extinguisher typically needs testing every 12 years, while a pressurized water extinguisher may need it every 5 years. Always check the manufacturer's label for the recommended testing interval.
If your extinguisher fails a hydrostatic test, it must be taken out of service and replaced. Never attempt to use an extinguisher that has not passed this test. If you are unsure about the status of your extinguisher, contact a local fire equipment professional for guidance.
- Check the pressure gauge monthly.
- Inspect the pin and tamper seal monthly.
- Look for dents, rust, or leaks monthly.
- Have a professional inspect annually.
- Follow manufacturer's hydrostatic testing schedule.
- Replace any extinguisher that fails an inspection.
When to Replace
Fire extinguishers do not last forever. Even with regular maintenance, they eventually need to be replaced. Common signs that it is time for a new one include a pressure gauge that doesn't read in the green zone, a broken handle or lever, or a damaged hose or nozzle.
Also, if you have used your extinguisher, even partially, it should be recharged or replaced. A partially discharged extinguisher is not reliable. If you are unsure whether your extinguisher can be recharged, check the manufacturer's instructions or consult a professional.
As a general rule of thumb, consider replacing your extinguisher every 10 to 12 years, even if it looks fine. This is because the seals and internal components can degrade over time. Always follow the manufacturer's recommendations for replacement intervals.
Additional Tips
Keep a record of all inspections and tests. This helps you track when the next service is due and provides documentation for your insurance company. Policies vary, and your insurer decides what is covered. Store this record in a safe place, such as with your home maintenance files.
Make sure everyone in your home knows where the extinguishers are and how to use them. Practice the PASS technique: Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep side to side. Knowing this can make a difference in an emergency.
If you have a fire extinguisher in your kitchen, check it more frequently, as grease and cooking residue can affect the nozzle. Also, if you live in an area with high humidity, moisture can cause corrosion, so inspect more often than the monthly minimum.
- Keep a written log of checks.
- Teach everyone the PASS method.
- Check kitchen extinguishers more often.
- Watch for corrosion in humid climates.
- Store extinguishers upright and secure.
- Replace after any use or damage.

Can I check my fire extinguisher myself?
Yes, you can do a basic monthly visual check yourself. Look at the gauge, ensure the pin is intact, and inspect for damage. However, an annual professional inspection is recommended to ensure the extinguisher is fully functional.
What does a professional inspection involve?
A professional inspection includes checking the pressure, verifying the extinguisher is properly charged, examining the hose and nozzle, and looking for any signs of corrosion or damage. They may also perform a hydrostatic test if due.
How long does a fire extinguisher last?
Most fire extinguishers last between 5 and 15 years, depending on the type and how well they are maintained. Check the manufacturer's label for the recommended service life. If the gauge is not in the green zone, replace it immediately.
