Electrical accidents mean workers get electrical shock or electrocuted when they are working in their workplaces. Some common causes of electrical accidents are shown as below:

    1. The switch of machine is badly contacted and badly insulated
    2. The live and neutral conductors are wrongly connected
    3. Under wet environment
    4. The electrode of welding machine is wet
    5. Without fuse in the machine
    6. Not proper use of electric appliances




    Cause of shock
      Electric shock results from touching a part which is 'live' or charged with electricity so that the victim's body completes the electrical circuit. It includes direct contact and indirect contact:

      Direct contact:
        1. Between earth and normally alive
        2. Between a metal live part and earth caused for instance by insulation breakdown or broken protective conductors
      Indirect contact:
        1. Insulation faults on live equipment
        2. Between earth and normally accessible metal part of apparatus that becomes accidentally faults due to a breakdown

    Effect of shock
      Injuries can vary from slight shock to fatal. Injuries are usually less severe when the electrical current by-pass nerve centres and vital organs. Electrical current that flows through the body from limb to limb usually passes through the heart and lungs cause serious injury, possibly death. The physical effects from an electrical shock most likely to cause death or serious injury are:
        1. Contraction of the chest muscles, resulting in an inability to breathe
        2. Inhibits the respiratory centre in the brain
        3. Causes fibrillation of the heart
        4. Destruction of tissues, nerves or muscles
