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.
This checklist is one of 16 in our fire safety maintenance checklists, covering fire dampers, alarms, emergency lighting, sprinklers, risers and fire doors — the statutory checks and their records.
