Electrical hazards in our business pose risks like fires and shocks. Learn how to identify common electrical hazards in business premises and keep your workplace safe. We’ll cover how they appear, the risks involved, and how to stay safe by taking the right steps at the right time.
Overloaded Power Sockets
Plugging too many devices into one socket is a common problem in offices and shops. It may seem harmless, but overloading a socket can create too much heat, which may cause sparks, smoke, or even fire.
Overloaded circuits can also cause sudden power loss, putting equipment and work at risk. Using approved extension leads with built-in safety switches is a better option.
To stay safe, make sure heavy-use devices like heaters, printers or kettles each have their own socket. You should also avoid plugging one extension lead into another, which is known as “daisy chaining”.
If your staff often rearrange desks or plug in extra items, review how sockets are used. Consider installing more fixed outlets to safely handle demand.
Damaged or Exposed Wiring
Over time, wires can crack, fray or come loose—especially in busy workplaces where furniture, chairs, and foot traffic may press against them.
Exposed wires are dangerous because they leave live electricity open to contact. If someone touches it, even by accident, it could result in a shock, serious injury or even fire.
Loose wires near desks, behind shelves or under carpets should be checked regularly. Cables with splits, dents or burn marks should be replaced immediately.
Extension leads run under carpets are especially risky, as heat can build up with no airflow. These should be rerouted or covered using proper trunking.
Faulty Electrical Equipment
Old or faulty appliances are a serious hazard. They may short out, overheat, or leak current, putting both people and property at risk.
Common signs include buzzing sounds, flickering power, or burning smells when the item is switched on.
All electrical equipment should be tested and inspected as part of your maintenance plan. Label each item with the last test date to help track usage over time. This includes printers, monitors, kitchen appliances, and any plug-in devices.
Encourage staff to report any equipment that seems faulty, even if it still works. Catching faults early helps prevent damage and reduces repair costs.
Water Near Electrical Sources
Water and electricity should always be kept apart. But in real workplaces, you often find sockets and extension leads close to taps, sinks, kettles, or cleaning buckets.
Even a small leak, splash, or wet floor can lead to electrical contact and create a serious hazard.
Keep all power sources raised off the floor and away from areas where water is used. Use signs or barriers in risky zones. Wipe up spills right away and train staff to report problems such as damp walls or slow leaks.
In kitchens, break rooms and cleaning areas, make sure all sockets have waterproof covers and use RCD protection to cut off power instantly in an emergency.
Lack of Regular Electrical Inspections
Even when things look fine, hidden faults can still be a threat. Cables wear out. Sockets loosen. Fuses age.
Without inspections, these problems build up over time and increase the risk of damage, downtime or injury.
All business premises should have a full electrical inspection every five years, or sooner if using high-powered tools or machinery. This helps protect your team and ensures your systems remain up to date with current safety standards.
Keep a record of each inspection. Make note of repairs, replacements or safety advice given by your electrician. This proves your business takes safety seriously.
A clear inspection history also helps when selling or insuring the property and shows you’ve taken the right steps to keep everyone safe.
