Portable Fire Extinguisher Maintenance Checklist
Keep portable extinguishers serviceable and in place — monthly visual checks, the annual basic service, pressure and seal verification, and signage to BS 5306.
What is a fire extinguisher maintenance checklist?
A portable fire extinguisher maintenance checklist is a structured list of the 10 preventive maintenance tasks — covering visual, functional and record-keeping checks — that keep a portable fire extinguisher running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core fire extinguisher checks
- Confirm each extinguisher is in its designated location and not obstructed
- Verify the extinguisher type suits the risk in that area
- Arrange the annual basic service by a competent technician
What is a portable fire extinguisher?
Portable fire extinguishers provide first-aid firefighting for the responsible person and trained staff. UK commissioning, siting, and maintenance follow BS 5306-3 (maintenance) and BS 5306-8 (selection and positioning). Extinguishers require a monthly visual check by the responsible person, an annual basic service by a competent technician, and extended service or replacement at defined intervals (typically five years extended service, ten years for CO₂). Correct type, location, signage, and accessibility matter as much as the unit's internal condition.
Typical Fire Extinguisher maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.
Visual Checks
- Confirm each extinguisher is in its designated location and not obstructed
- Check the pressure gauge reads in the green operating band (where fitted)
- Verify the safety pin and tamper seal are intact
- Inspect the body, hose, and horn for damage, corrosion, or blockage
- Confirm the service label and next-service date are current
- Check location signage is present, correct, and visible
- Confirm wall brackets or stands are secure and at the correct height
Functional Checks
- Verify the extinguisher type suits the risk in that area
Record Keeping
- Arrange the annual basic service by a competent technician
- Record monthly checks and the annual service in the fire log book
