Fire Extinguisher Maintenance 101

Posted June 15, 2015 by Koorsen Fire & Security

fire extinguisher maintenance

Having a sufficient number of the right type of fire extinguishers present at your facility is important. Yet, without proper maintenance, these units may not provide the protection you need. Why? Your extinguishers must be kept in working order, otherwise they may fail to function at full capacity (or at all) when called upon to subdue a fire. In addition, not performing the required maintenance can lead to costly code violations.

Therefore, it is important to learn the basics of fire extinguisher maintenance and what is required to ensure that they are at peak readiness at all times. Check out the fire extinguisher maintenance steps below.

Monthly Inspections

The NFPA requires that all fire extinguishers be inspected at least once per calender month. During this inspection, the following questioned will be answered:

  • Are the units in proper locations?
  • Are the units in clear view and properly accessible?
  • Are the units in clean condition?
  • By the naked eye do the units appear to be operable?
  • Have the monthly inspection tags been properly signed?

Koorsen personnel also complete the following rigorous 12 point inspection on every unit:

  1. Visually inspect extinguisher.
  2. Check the test and maintenance dates.
  3. Weigh extinguisher. (CO2)
  4. Visually inspect pressure gauge (when applicable).
  5. Remove safety pull pin.
  6. Install new tamper seal (some units may require additional inspection procedures).
  7. Remove discharge hose and inspect valve assembly.
  8. Check CO2 hoses for continuity (when applicable).
  9. Clean extinguisher.
  10. Attach a new certification tag.
  11. Complete Fire and Safety Report.
  12. Ensure customer understands completed work.

Annual Maintenance

The NFPA requires that maintenance on all portable fire extinguishers present at your facility be completed on an annual basis. This is the minimum requirement, and if your monthly inspections reveal any problems, then maintenance may need to be performed even more often.

This maintenance includes an annual external examination of all extinguishers, and according to NFPA 10 7.3.2, its purpose is to:

  • catch signs of physical damage or any corrosion that may be present
  • determine if the nozzle has become blocked
  • ensure that the operating instructions are still on the unit, facing forward and able to be clearly read
  • check that the HMIS is present
  • fix any issues which are discovered

Finally, tamper seals must be installed after your annual maintenance is complete.

5-Year Hydrostatic Test

The hydrostatic test is required every five years for carbon dioxide, water-based extinguishers and some other types.

6-Year Maintenance

  • 6 year maintenance is required for all extinguishers which are subject to the 12 year hydrostatic test. This includes most stored-pressure extinguishers which can be recharged.
  • If the extinguisher passes the six year inspection, a label needs to be affixed to the unit stating that the extinguisher has been inspected.

The tag lists the person who completed the inspection and their affiliated agency, so the inspection must be completed by a qualified organization, such as Koorsen Fire & Security.

12-Year Hydrostatic Test

  • The 12-year hydrostatic test is required on most stored-pressure units and all cartridge-operated extinguishers.
