General Replacement Guidelines

Most fire extinguishers can serve for 10-12 years. Actually, the replacement schedule is based on the type of extinguisher, as well as its maintenance record:

  • Disposable fire extinguishers: Every 12 years
  • Rechargeable fire extinguishers: Can last longer with proper maintenance but should be replaced if they fail inspections or after a maximum of 12 years

Factors Affecting Replacement Frequency

Several factors can necessitate earlier replacement:

  • Physical damage (dents, corrosion, leaks)
  • Missing or broken parts
  • Pressure gauge issues
  • Failed inspections or hydrostatic tests
  • Exposure to extreme temperatures

Inspection and Maintenance Schedule

To ensure your fire extinguishers remain in good working condition:

Monthly Visual Inspections

  • Check the extinguisher is visible and accessible 
  • Check for damage, corrosion, or leaks 
  • Check the pressure gauge is in the operable range 
  • Check the operating pin and tamper seal are intact 
  • Check the operating instructions are legible 
  • Take advantage of annual professional inspections 
  • Check all parts and test pressure 

6-Year Maintenance: Rechargeable models must undergo internal inspection and recharging every 6 years. 

12-Year Hydrostatic Testing: Pressurized extinguishers require hydrostatic testing every 12 years to ensure the integrity of the cylinder.

Signs Your Extinguisher Needs Replacement

Replace your fire extinguisher immediately if you notice:

  • Visible damage, corrosion, or leaks
  • A broken handle or missing parts
  • The pressure gauge needle outside the green zone
  • A missing or outdated inspection tag.
  • Proper Disposal

Never throw away fire extinguishers in the regular trash. 

Safe Disposal

  • For non-empty fire extinguishers: Contact your local fire department or hazardous waste facility
  • For empty fire extinguishers: Release all pressure, remove the head, and recyclRemembert an appropriate facility and replacement.
