Fire Extinguisher Hydrostatic Testing

Hydrostatic Testing

Fire extinguishers are required to have routine Hydrostatic Tests. We are fully licensed by the DOT (license RIN# N213) to perform all hydrostatic pressure tests on fire extinguisher cylinders.

Ask about our swap out program to ensure your property does not go uncovered for the duration of the test!

Only a visual inspection is not enough to guarantee that the portable fire extinguisher will function properly when needed. In order to prevent any hazardous and dangerous situations, all fire extinguishers must undergo a hydrostatic test by skilled and certified experts who use adequate equipment and testing tools.

Hydrostatic testing is the technique that is used to test all the crucial components of portable fire extinguishers. These components include the cylinder, shell, hose, assembly, and others. During this procedure, the cylinder and the whole vessel is pressurized with a liquid to check for any leaks or structural flaws.

Steps for Hydrostatic testing:

Hydrostatic testing is a multi-step procedure, which includes:

  1. Removal of the hose
  2. Emptying of the cylinder by discharging its contents completely
  3. Removal of the valve
  4. Performing the pressure testing, where the tank is filled with water and then pressurized up to 125 to 150 percent of the functional capacity. During this test, the internal pressure is monitored. A decrease in this shows leaks and deformities, suggesting a replacement.
  5. Draining out the liquid and refilling with a fresh fire suppressant
  6. Updating the decals to show successful hydrostatic testing.
  7. Re-pressurization of the vessel to its functional capacity
  8. Re-installing the safety components for optimum fire protection

Typically, you should get a fire extinguishing tank hydrostatically tested every 12 years from its manufacture date. The hydro date on the tank can be found in different places on the vessel. It can either be on the label, on the bottom outside corner of the cylinder, or the underside of the cylinder.

Besides hydrostatic testing, monthly inspection is the key to ensure a sufficient fire safety protocol. In fact, it is one of the NFPA requirements to conduct a monthly inspection of your fire extinguishers.

The necessary steps to perform a monthly inspection:

  1. Weigh the tank to make sure that it is filled adequately.
  2. Check to see if the safety seals are proper and intact
  3. Look to make sure that the tank has no physical damage, such as dents, rust, or any other form of wear and tear.
  4. Make sure that the pressure gauge is in the functional and acceptable range.

Maintenance, testing, and proper inspections of your building’s fire extinguishing tanks are some essential requirements by the law. Contact us to learn more about our hydrostatic testing service.
