Should I Test My Fire Extinguishers?
If you recently installed portable fire extinguishers in your Texas building, they’re a crucial resource for minimizing property damage and safeguarding lives if a fire breaks out. However, these devices only work effectively when the canisters are fully charged and in proper working order. You may be wondering if you should test them by discharging a small amount from time to time. The short answer is no. Here’s why.
Why Avoid DIY Fire Extinguisher Testing?
Releasing even a small amount of fire-extinguishing agent during a do-it-yourself test can reduce the pressure in the canister. Because full pressure gives you the best chance of stopping a small fire before it spreads, any pressure loss could render your extinguisher useless during a real emergency.

Professional Hydrostatic Testing Is a Must
While you should never test your fire extinguisher on your own, that doesn’t mean all testing is off the table. In fact, NFPA 10: Standard for Portable Fire Extinguishers mandates a process called hydrostatic testing.
Why is hydrostatic testing necessary?
Over time, the chemicals stored under pressure can weaken the extinguisher’s canister. Hydrostatic testing ensures that the tank shell, nozzle, and hose are all in good condition to prevent rupturing or other failures. Because this test requires specific equipment and expertise, only a certified professional should perform it.
What is hydrostatic testing?
The test begins by completely emptying the fire extinguisher of its pressurized contents. Next, the canister is filled with colored water and brought to a high pressure for about 30 seconds. The shell must hold this pressure for a specified duration—usually one minute—while the unit is inspected for leaks, bulging, or signs of metal fatigue. Certain models also require the hose to be tested in the same way.
How often is hydrostatic testing needed?
Professional testing is mandatory every five years for pressurized water, wet chemical, and carbon dioxide extinguishers. Dry chemical extinguishers must be tested every 12 years.
Non-rechargeable canisters are an exception. They must be taken out of service 12 years after their manufacturing date. The same applies to any rechargeable extinguisher that fails a hydrostatic test.
Monthly DIY Fire Extinguisher Inspections Are Recommended
Instead of partially discharging your extinguisher to check its functionality, simply examine the outside for visible signs of damage or defects. Every month, follow these steps:
- Confirm the extinguisher is accessible and properly mounted.
- Ensure the pin is in place, the tamper seal is unbroken, and the nozzle isn’t blocked.
- Check for any dents, corrosion, or leaks.
- Inspect the pressure gauge. The needle should be in the green zone to indicate a full charge. Pick up the extinguisher to gauge whether it feels full.
- Verify that the operating instructions are clear and facing outward.
- Look at the date on the service tag. If it’s been over 12 months since your last professional inspection, schedule one right away.
