Fire Extinguisher Testing in Dallas and the DFW Metro Area
Introduction to Fire Extinguisher Testing
Fire extinguishers are only as effective as their internal condition allows. Even if an extinguisher looks fine externally, its cylinder, valves, or pressure may degrade over time — making it unreliable during an emergency. That’s why regular fire extinguisher testing is essential.
At AllStar Fire Extinguisher Service, we provide professional fire extinguisher testing in Dallas TX, including hydrostatic testing, recharging, and certification services. Backed by State License ECR 2019 and more than 25 years of field experience, our company ensures every extinguisher meets or exceeds NFPA 10 standards for safety and compliance.
Since 2015, we’ve served businesses throughout Dallas, Collin, Denton, Tarrant, and Ellis counties with expert inspection and testing services designed to keep equipment reliable, documentation up to date, and workplaces fully protected.
Why Fire Extinguisher Testing Matters
Over time, extinguishers are exposed to environmental conditions, pressure fluctuations, and mechanical wear that can compromise their integrity. Hydrostatic testing confirms the extinguisher’s cylinder can safely hold pressure, while recharging ensures it contains the correct extinguishing agent and propellant.
Testing is not optional — it’s a legal and safety requirement under NFPA 10, OSHA, and Texas fire protection regulations. If an extinguisher fails or has not been tested on schedule, it must be removed from service until it passes inspection or is replaced.
Routine testing helps prevent unexpected failures, reduces liability, and gives business owners confidence that their extinguishers will perform exactly as intended when needed.
Types of Fire Extinguisher Testing We Offer
Hydrostatic Testing
Hydrostatic testing involves filling the extinguisher’s cylinder with water and pressurizing it to a specific level to verify its structural strength. This process ensures the cylinder can safely contain pressurized contents without leaks or deformation.
Pressure and Leak Testing
In addition to hydrotesting, we perform low-pressure leak tests to ensure valves, hoses, and fittings remain airtight. Even minor leaks can cause gradual depressurization and failure during emergencies.
Extinguisher Recharging
After any use or testing, extinguishers must be recharged with the proper extinguishing agent and propellant. We refill and pressurize units to manufacturer specifications, verifying that pressure readings, weight, and chemical levels are accurate.
Six-Year Maintenance
Every six years, stored pressure dry chemical extinguishers must be emptied, inspected internally, and refilled. We perform this maintenance service alongside testing to extend the life and reliability of your extinguishers.
Replacement and Certification
If an extinguisher fails testing or shows signs of corrosion, cracks, or deformation, it must be removed from service. We supply and install certified replacements to keep your facility compliant without interruption.
Our Testing Process
Collection and Tag Review
We record model numbers, serials, and current tag information for every extinguisher.
External Inspection
The cylinder, valve, and hose are checked for corrosion, dents, or physical damage.
Hydrostatic or Pressure Testing
The extinguisher is tested under controlled conditions to verify its integrity.
Drying and Reassembly
The cylinder is thoroughly dried and reassembled with new O-rings, seals, and gaskets if needed.
Recharging
The extinguisher is refilled with the correct extinguishing agent and re-pressurized.
Tagging and Documentation
A new tag and test record are attached, showing the test date and technician license number.

frequently asked questions
How often is hydrostatic testing required?
Most dry chemical extinguishers require testing every 12 years, while CO₂ and high-pressure models require testing every 5 years.
Can a failed extinguisher be repaired?
If a failure is due to a minor issue like a valve or hose, repairs can often be made. However, cylinders that fail hydrostatic testing must be replaced.
Do you perform testing on-site?
In most cases, testing is done at our licensed facility due to specialized equipment requirements, but we provide pick-up and return services for your convenience.
Are testing records provided?
Yes. Every tested extinguisher receives a certification tag and documented record for your compliance files.
What happens to extinguishers that fail testing?
Failed units are safely depressurized, marked “unserviceable,” and properly disposed of according to EPA and DOT regulations.
When Fire Extinguishers Require Testing
Fire extinguishers must be tested when:
- They reach their
six-year or twelve-year maintenance cycle
- The pressure gauge shows low or inconsistent readings
- They have been
used or partially discharged
- The extinguisher has been
dropped, damaged, or corroded
- Required by the fire marshal, insurance provider, or safety audit
Our scheduling system tracks each extinguisher’s maintenance date and notifies you before it’s due for testing, keeping you inspection-ready year-round.
