8 common electrical hazards in the workplace

Posted by Tracy Seward

  • Learn about electrical hazards in the workplace and how to protect staff.
  • Understand how the Electricity at Work Regulations (1989) affect your business.
  • Identify common electrical hazards – from damaged equipment to overloaded sockets.

While your workplace may not seem a high-risk environment for electrical injuries, electrical safety should be considered by all businesses. Poorly maintained or incorrectly used electrical equipment can cause fires, electric shock or electrocution – resulting in life-changing injuries or death. This guide outlines the electrical hazards to look out for and how to manage them in the workplace.

Help keep your workplace safe from electrical hazards with our Electrical Safety online training course. Tailored to employees, it helps staff identify electrical hazards at work and how to deal with them.

What are the Electricity at Work Regulations?

For employers, maintaining a healthy and safe workplace is vital – and electrical safety is part of that.

Every year, around 1,000 accidents at work involving electricity are reported to the Health and Safety Executive and about 30 people die from injuries caused by electrical hazards.

Under the Electricity at Work Regulations (1989), employers must make sure all electrical equipment is safe. It should be checked, properly installed and regularly inspected and maintained by a qualified person.

Employers must carry out an electrical risk assessment of any electrical hazards. The assessment should detail who could be harmed by electrical hazards, how the level of risk has been established and the precautions that have been taken to control the risk. You must also provide staff with training on electrical safety in the workplace.

Employers are also required to report certain incidents and injuries to the Health and Safety Executive.

Employers risk fines for not complying with the regulations, so it’s essential to be aware of electrical hazards in the workplace.

What injuries can be caused by electrical hazards?

The main injuries caused by electrical hazards are:

  • Electrocution.
  • Electrical burns, which occur when the electrical current enters and exits the body.
  • Electric shock caused when contact is made with a live wire or equipment that is not grounded.
  • Secondary injuries resulting from the effects of shock, such as being thrown to the ground or falling off a ladder.

Eight common electrical hazards

Many appliances and equipment in the workplace present an electrical hazard, but the most common hazards are:

Damaged equipment and power tools

Using damaged electrical equipment, such as construction power tools, can be very dangerous. Broken tools and equipment should not be used until they are fixed and certified by someone qualified to do so.

Frayed, loose or exposed electrical cables

Electrical hazards workplace safety - frayed cable

Electrical cords on equipment contain securely insulated live wires. If the cable becomes frayed or cracked, the live wire can be exposed and lead to electrical fires or electric shock. Damaged cables should be reported and repaired by a qualified person, and should not be temporarily fixed with tape.

Using electrical equipment near water or with wet hands

Water can significantly increase the chance of electrocution so electrical equipment should not be used near a source of water or operated with wet hands. If the equipment does get wet, a qualified electrician should inspect it before it is used again.

Overhead power lines

The high voltage in overhead electrical lines can result in significant burns and electrocution. If you have workers working near overhead power lines, it is recommended that a minimum distance of 10 feet from the lines and nearby equipment is maintained. Do not store equipment or materials under overhead power lines, and use safety barriers and signs to warn others of the hazard.

Incorrect use of replacement fuses

If you’re fitting or replacing a fuse, you must use the right fuse for the appliance so that it doesn’t overheat. Check the manual or the label on the appliance to find out the wattage and the correct fuse required.

Overloaded sockets

Overloaded sockets in the workplace are dangerous

Many offices are full of computers and other equipment that all need plugging in, often with lots of extension leads and adapters that can result in a spaghetti of cables and plugs. Ideally, an individual power socket should provide electricity to a single item, such as a computer monitor or printer.

If you do need to power several appliances from a single socket, use a fused, multi-way bar extension lead with surge protection rather than relying on a basic block adapter when plugging in additional equipment.

Do not overload the extension lead by plugging in several appliances that exceed the maximum electrical current level stated for the extension lead. Never plug an extension lead into another extension lead.

Smoke and smells from equipment

Smoke and burn damage is a warning sign of electrical hazards

A smell of hot plastic, sparks or smoke coming from plugs, appliances or sockets are signs of an electrical hazard so keep an eye out for these danger signs. Get help from a qualified person and turn off the electrical supply to any equipment that appears to develop an electrical fault.

Improper grounding

All electrical equipment and devices must be earthed or grounded. If not, you’re at risk of electrocution. Make sure that electrical equipment is periodically checked and certified by a qualified person.

Who is most at risk from electrical hazards?

Engineers, electricians, engineers and overhead line workers are among the professions that are most exposed to electrical hazards. Installation, repairs, inspection and maintenance of electrical equipment are common activities that lead to accidents.

Agricultural workers are also at high risk because machinery or equipment can come into contact with overhead power lines on farmland.

On average, one farm worker dies this way each year, and in the five years to 2018, there were 1,140 near-miss incidents involving machinery and equipment contacting overhead electric power lines where serious injury or death was a possibility.

Most workplaces have some electrical hazards, though. The high volume of electrical equipment in most offices can expose workers to shocks, burns and fire.

Electrical hazard assessment checklist

Employers should make sure all employees are aware of electrical safety at work.

Staff should be encouraged to keep an eye out for any risks, and if they spot faulty equipment, it should be reported to a supervisor or whoever is in charge. The equipment should stop being used immediately and be checked by a qualified person.

Here are some precautions to take:

  • Make sure that employees know how to use electrical equipment safely.
  • Ensure enough sockets are available so that they aren’t overloaded.
  • Switch off and unplug appliances before cleaning them.
  • All appliances should be turned off at the end of the day.
  • Keep an eye out for trailing cables which might cause people to trip or fall.
  • Make sure that anyone working with electricity has been properly trained.
  • Keep floors and work surfaces dry so that electrical equipment doesn’t come into contact with water or other liquids.
  • Keep a minimum of three feet of clearance in front of electrical panels.
  • Electrical cords should not be used through high-traffic areas, across doorways or under carpets as they could be damaged and cause accidents.
If your organisation works with electrical systems or equipment, make sure your business meets compliance requirements with our Electrical Safety online training course – helping staff to understand, spot and report electrical hazards in the workplace.
