Case Study: How Regular PAT Testing Prevented a Workplace Fire

Electrical fires are a serious risk in any workplace, yet many businesses underestimate how preventable they are. This case study highlights how regular PAT testing (Portable Appliance Testing) stopped a potential disaster before it happened, protecting staff, property, and business operations.


The Workplace

A medium-sized marketing agency in Birmingham relied heavily on electrical equipment, including:

  • Computers and monitors
  • Printers and photocopiers
  • Kitchen appliances in staff areas (kettles, microwaves, fridges)
  • Extension leads and surge protectors

With over 50 employees using this equipment daily, the risk of an electrical fault was significant.


The PAT Testing Program

The agency had implemented a regular PAT testing schedule, with annual checks for all office appliances and quarterly inspections for high-use devices like kitchen equipment and extension leads.

During the most recent inspection, the PAT engineer conducted:

  1. Visual inspections – checking cables, plugs, and appliance casings for damage
  2. Electrical tests – assessing earth continuity, insulation resistance, and polarity
  3. Labelling and documentation – marking pass/fail status and recording all results

The Discovery

During the inspection, the engineer identified a faulty kettle in the staff kitchen:

  • The internal wiring showed signs of insulation breakdown
  • The plug was slightly burnt, indicating overheating
  • The appliance posed a real fire risk if left in use

Without PAT testing, this kettle might have been used daily, potentially causing a serious electrical fire.


Action Taken

The faulty kettle was immediately removed from service and replaced with a certified, safe appliance. The engineer updated the agency’s PAT records and flagged the risk for all kitchen appliances, prompting staff to be more vigilant about checking their equipment.


The Outcome

Thanks to regular PAT testing:

  • A potential electrical fire was prevented
  • Staff remained safe, and no property damage occurred
  • The agency maintained compliance with health and safety regulations
  • Insurance obligations were met, ensuring continued coverage

This incident highlights how proactive PAT testing is a cost-effective way to manage risk and protect a business.


Key Takeaways

  1. Regular PAT Testing Saves Lives – Small electrical faults can escalate into major hazards.
  2. High-Use Appliances Are High-Risk – Equipment used frequently or by multiple people requires closer attention.
  3. Documentation Protects Your Business – Records from PAT testing demonstrate compliance and reduce liability.
  4. Prevention Is Cheaper Than Recovery – Replacing a faulty appliance is far less costly than dealing with a fire.

Final Thoughts

This case study proves that PAT testing isn’t just a regulatory box to tick—it’s a vital safety measure. By scheduling regular inspections and acting on any faults immediately, businesses can prevent accidents, protect staff, and safeguard property.

👉 If your workplace hasn’t had a PAT test recently, now is the time to schedule one. Small checks today can prevent major disasters tomorrow.
