B4Fire extinguishers come in all shapes and sizes, Ralph J. Perry can help you select the best extinguisher for your situation. Once it is installed, we will show you how to use your fire extinguisher correctly and how to conduct monthly inspections. Along with installing, hydro-testing, and recharging your fire extinguisher, we will also perform annual inspections and service as required by NFPA codes.

Annual Fire Extinguisher Inspection and Certification

  1. SHOP 033Clean Extinguisher
  2. Visual Examination – which is performed on entire cylinder inspecting for any dents, rust, corrosion, pitting or other cylinder damage.
  3. Check Pressure Guage – to ensure than the extinguisher is fully pressurized.
  4. Check cylinder date or last hydrotest date – to determine need for hydrotesting or 6-year maintenance service
  5. Heft Extinguisher – to ensure correct amount of agent.
  6. Remove Nozzle or Discharge Hose – look for signs of blockage
  7. Remove Pull Pin.
  8. Ensure handle and lever actuation – for correct discharge operation.
  9. Confirm Extinguisher is properly located to meet the hazard.
  10. Inspect wall hook or mounting bracket – making sure it is securely and correctly mounted so not to be dislodged.
  11. Attach inspection and recertification tag.
6-Year Maintenance

Every 6 years, stored-pressure fire extinguishers that require a 12-year hydrostatic test shall be emptied and subjected to the applicable maintenance procedures.  When the applicable maintenance procedures are performed during periodic recharging or hydrostatic testing, the 6-year requirement shall begin from that date.

– NFPA 10 – 6.3 – Maintenance

Hydrotest Frequency

“At intervals not exceeding those specified in the table below, fire extinguishers shall be hydrostatically retested. The hydrostatic retest shall be conducted within the calendar year of the specified test interval. In no case shall an extinguisher be recharged if it is beyond its specified retest date.”

Extinguisher Type
Test Interval                         (Years)
Stored-pressure water, loaded stream, and/or antifreeze
