As an employer, it’s your legal responsibility to ensure collective employee protection and safety. The Health and Safety at Work Act 1974 stipulates all employer responsibilities in this regard, and within that lies the Electricity at Work Regulations 1989.

While most commercial and industrial spaces can go years without any severe electrical faults or issues, that is not to say that they shouldn’t be mitigated. If not properly managed, electricity can have severe consequences, with faulty installations and equipment sometimes being the root cause of fires, explosions, electrocutions, and serious human injuries or even death. 

Conducting regular electrical safety checks is therefore vital; having them professionally tested will ensure that all personnel and your business remain harm- and risk-free. As part of any company’s health and safety policy, regular electrical testing and assessments should be conducted in line with HSE Regulations .

Key Assessments and Inspections

Maintaining electrical safety requires a multifaceted approach involving both proactive checks and reactive incident investigation. There are two main categories of tests you can conduct to assess the safety and stability of electrical systems. They are:

1. Fixed Wire Testing
2. Portable Appliance Testing (PAT)

Fixed wire testing (commonly referred to as EICR testing) refers to the assessment of the main electrical wiring systems under BS 7671. Detailed periodic electrical inspections will usually involve visual inspections, operational testing (including RCDs) and reporting of all compiled faults and issues.

PAT testing is a process where all electrical appliances and equipment undergo individual testing and evaluation to ensure they are safe to use. All portable appliances need to be in good working order, while being reliable for earth continuity, insulation resistance, and polarity. If any problems are identified, the appliance must be repaired or replaced. 

While not compulsory, it’s recommended that all commercial property owners conduct PAT tests every few months, depending on the nature and use of the appliance or portable device. Meanwhile, fixed wiring installations must be tested and inspected every 5 years or sooner if there is a substantial change in the use or structural layout of the building. In other words, if any renovations or alterations have affected the electrical wiring composition, a fixed wire test must be commissioned. The

Some of the main risks of faulty electrical wiring or devices include: for

• Electric shocks: Direct contact with live parts or “leakage” from faulty insulation, tools and cords can result in shocks, burns and even severe health issues.
• Arc flashes and blasts: Short circuits can trigger explosive blasts which can cause immediate serious injuries and burns, particularly if metals and flammable chemicals are nearby.
• Fires: Faulty electrical installations and overloaded circuits are a major cause of workplace fires. Electrical fires warrant the use of specific extinguishers and prevention methods.
• Explosions: Certain industrial environments with combustible dust, vapours and gases can literally fuel an electrical explosion if equipment is not properly rated and maintained.

To enable complete electrical safety across your organisation, consider the following:

• Avoid overloading circuits, by spreading the use of portable devices to multiple sockets.
• Use properly grounded outlets and quality-marked extension cords to reduce the risk of fires and shocks.
• Keep flammable materials away from electrical outlets to prevent any from catching fire and posing an immediate safety risk.
• Ensure all appliances are in well-ventilated areas for the proper dispersion of heat.
• Verify that all fuses and units are installed correctly and functional; disconnect and replace any faulty equipment as soon as you suspect a fault.
• Remove any electrical cords from areas of high foot traffic to reduce the chances of slips, trips, and falls, while ensuring the integrity of the cords.
• Report and follow HSE recommendations if employees suffer electric shocks, burns, or other injuries.
• If an electrical fire cannot be immediately treated using the correct fire extinguishing equipment, call the fire and rescue services immediately.
