Electrical Safety & Guidance

Share this page

Electricity can kill or severely injure people and cause damage to property. However, you can take simple precautions when working with or near electricity and electrical equipment to significantly reduce the risk of injury to you, your workers and others around you.

  • What are the hazards?

    • The main hazards of working with electricity are:
      • Electric shock and burns from contact with live parts.
      • Injury from exposure to arcing, fire from faulty electrical equipment or installations.
      • Explosion caused by unsuitable electrical apparatus or static electricity igniting flammable vapours or dusts, for example in a spray paint booth.
      • Electric shocks can also lead to other types of injury, for example by causing a fall from ladders or scaffolds etc..
  • What do I have to do?

    • You must ensure an assessment has been made of any electrical hazards, which covers:
      • Who could be harmed by them.
      • How the level of risk has been established.
      • The precautions taken to control that risk. 
      • The risk assessment should take into consideration the type of electrical equipment used, the way in which it is used and the environment that it is used in.
      • You must make sure that the electrical installation and the electrical equipment is:
      • Suitable for its intended use and the conditions in which it is operated.
      • Only used for its intended purpose. 
      • In wet surroundings, unsuitable equipment can become live and make its surroundings live too. Fuses, circuit-breakers and other devices must be correctly rated for the circuit they protect. Isolators and fuse-box cases should be kept closed and, if possible, locked.
      • Cables, plugs, sockets and fittings must be robust enough and adequately protected for the working environment. Ensure that machinery has an accessible switch or isolator to cut off the power quickly in an emergency.
  • Maintenance

    • So far as is reasonably practicable , you must make sure that electrical equipment and installations are maintained to prevent danger.
    • Users of electrical equipment, including portable appliances, should carry out visual checks. Remove the equipment from use immediately and check it, repair it or replace it if:
      • the plug or connector is damaged.
      • the cable has been repaired with tape, is not secure, or internal wires are visible etc.
      • burn marks or stains are present (suggesting overheating).
    • Repairs should only be carried out by a competent person (someone who has the necessary skills, knowledge and experience to carry out the work safely).
    • Have more frequent checks for items more likely to become damaged (eg portable electrical tools and equipment that is regularly moved, or used frequently or in arduous environments). Less frequent checks are needed for equipment less likely to become damaged (eg desktop computers etc). 
    • Visual checks are not usually necessary for small, battery-powered items, or for equipment that works from a mains-powered adaptor (laptops or cordless phones etc). However, the mains-powered adaptor for such equipment should be visually checked.
    • Consider whether electrical equipment, including portable appliances, should be more formally inspected or tested by a competent person. Also think about the intervals at which this should be done.
    • An HSE leaflet Maintaining portable electrical equipment in low-risk environments can help you decide whether and when to test portable appliances in low-risk environments.
    • Make arrangements for inspecting and testing fixed wiring installations, ie the circuits from the meter and consumer unit supplying light switches, sockets, wired-in equipment (eg cookers, hairdryers) etc, to be carried out regularly so there is little chance of deterioration leading to danger. This work should normally be carried out by a competent person, usually an electrician.
  • When is someone competent to do electrical work?

    • In this context, a competent person is someone who has the suitable training, skill and knowledge for the task to be undertaken to prevent injury to themselves and others.
    • A successfully completed electrical apprenticeship, with some post-apprenticeship experience, is one way of demonstrating technical competence for general electrical work.
    • More specialised work, such as maintenance of high-voltage switchgear or control system modification, is almost certainly likely to require additional training and experience.
  • Key points to remember

    • Ensure that workers know how to use the electrical equipment safely.
    • Make sure enough sockets are available. Check that socket outlets are not overloaded by using unfused adaptors as this can cause fires.
    • Ensure there are no trailing cables that can cause people to trip or fall.
    • Switch off and unplug appliances before cleaning or adjusting them.
    • Ensure everyone looks for electrical wires, cables or equipment near where they are going to work and check for signs warning of dangers from electricity, or any other hazard. Checks should be made around the job, and remember that electrical cables may be within walls, floors and ceilings (especially when drilling into these locations) etc.
    • Make sure anyone working with electricity has sufficient skills, knowledge and experience to do so. Incorrectly wiring a plug can be dangerous and lead to fatal accidents or fires.
    • Stop using equipment immediately if it appears to be faulty - have it checked by a competent person.
    • Ensure any electrical equipment brought to work by employees, or any hired or borrowed, is suitable for use before using it and remains suitable by being maintained as necessary.
    • Consider using a residual current device (RCD) between the electrical supply and the equipment, especially when working outdoors, or within a wet or confined place (see HSE's electrical safety at work site).
  • Overhead electric lines

    • Be aware of the dangers of working near or underneath overhead power lines. Electricity can flash over from them, even though machinery or equipment may not touch them.
    • Don't work under them when equipment (eg ladders, a crane jib, a tipper-lorry body or a scaffold pole) could come within a minimum of six metres of a power line without getting advice. Speak to the line owner, eg the electricity company, railway company or tram operator, before any work begins.
  • Underground cables

    • Always assume cables will be present when digging in the street, pavement and/or near buildings.
    • Consult local electricity companies and service plans to identify where cables are located.
    • Tools to help people stay safe

      • As well as their popular socket calculator and product recall checker, they have taken advantage of digital technology to develop tools that will help people stay safe when shopping online or wanting to check the electrical products in their homes are safe.
      • They have developed an app for Alexa Skills and Google Nest which you can use to check whether the products in your home have been subject to a recall or safety notice. 
      • Their 'Check It Out' plug-in is available for Chrome, Firefox, MS Edge and Safari, and will let you know if you are buying from a third party seller on Amazon Marketplace or eBay, rather than from a trader you know and trust.

      • Product misuse is the top cause of accidental fires in British homes and the number has increased by over a third since 2009.
      • Millions of people commit basic electric safety 'blunders' in the home without realising that they are exposing themselves to the risk of fire or electric shock.
      • Modern living means we are using more and more electrical appliances in the home. Just twenty years ago, the average UK home would have had a hi-fi system and one TV or video. Today, it is more likely that there are at least two TVs, a DVD player, a satellite receiver, games console, microwave, computer and more. So, the risk of electrical accidents in the home is much higher than before.
