Fire Extinguisher Inspection Checklist: What You Need to Know

Fire extinguishers are the first line of defense against small fires in any commercial building. In a restaurant or industrial setting, having functioning extinguishers can mean the difference between a minor incident and a catastrophic loss.

To ensure your fire extinguishers are ready when you need them, they must be inspected regularly. The National Fire Code of Canada and NFPA 10 require both monthly visual inspections and annual professional maintenance.

The Monthly Visual Inspection Checklist

As a business owner, you or a designated staff member should perform a visual check of all fire extinguishers every 30 days. Use this checklist:

  • [ ] Accessibility: Is the extinguisher clearly visible, marked with signage, and free of obstructions (not blocked by boxes, coats, or equipment)?
  • [ ] Physical Condition: Check for obvious physical damage. Are there dents, rust, corrosion, or leaks?
  • [ ] Pressure Gauge: Look at the dial on the pressure gauge. Is the needle in the green zone? If it is in the red zone (undercharged or overcharged), it needs immediate service.
  • [ ] Safety Seal and Pin: Is the plastic tamper seal intact? Is the metal pull pin securely in place?
  • [ ] Operating Instructions: Are the instructions on the label legible and facing outward?
  • [ ] Nozzle and Hose: Inspect the nozzle or hose for cracks, dry rot, or blockages (like spiders or dust buildup).
  • [ ] Inspection Tag: Initial and date the paper tag attached to the extinguisher to document the monthly check.

Professional Inspections and Maintenance

While monthly visual checks can be done by your staff, professional servicing is required by law at specific intervals:

1. Annual Certification (Every Year)

Once a year, a certified fire protection technician must perform a full physical inspection of each extinguisher. They check the internal components, weigh the unit to verify contents, check the date of manufacture, and attach a certified inspection tag valid for one year.

2. Six-Year Maintenance (Every 6 Years)

Every 6 years, dry chemical fire extinguishers must be emptied and subjected to an internal inspection. The technician replaces the valve stem, seals, and recharging agent before pressurizing the unit again.

3. Hydrostatic Testing (Every 12 Years)

Every 12 years, the extinguisher cylinder must undergo hydrostatic testing. This involves pressure testing the cylinder using water to ensure there are no structural weaknesses or leaks that could cause the cylinder to rupture.

Choosing the Right Extinguisher for Commercial Kitchens

Standard ABC dry chemical extinguishers are great for office spaces but should not be used near deep fryers. Commercial kitchens require a Class K (Wet Chemical) fire extinguisher.

Class K extinguishers discharge a fine mist of potassium acetate, which reacts with hot cooking oils to form a soapy layer (saponification), cooling the oil and suffocating the grease fire without splashing.
