Use this fire extinguisher maintenance checklist to ensure compliance, improve safety, and keep extinguishers inspection-ready at all times.

Fire extinguishers are one of the most critical pieces of life safety equipment in any facility. However, simply having extinguishers on the wall is not enough. Regular maintenance and inspections are required to ensure they function properly during an emergency and remain compliant with fire safety regulations.

This fire extinguisher maintenance checklist outlines the key steps facility managers, safety officers, and inspection teams should follow to keep their equipment in proper working condition.

Why Fire Extinguisher Maintenance Is Important

Routine fire extinguisher maintenance helps to:

  • Ensure extinguishers operate correctly during an emergency

  • Maintain compliance with NFPA and local fire codes

  • Identify damaged, discharged, or missing units early

  • Reduce liability and improve overall workplace safety

Neglected extinguishers can fail when they are needed most, putting lives and property at risk.
