Electrical shock

Where a serious electrical shock is suspected, act to break the contact between the casualty and the electrical supply.

• If it is possible to do so safely, you should turn off the source of electricity, by switching off the current at the mains, turning the power off at the circuit board etc.
• Alternatively, move the source of the shock away using an object of low conductivity. Stand on a dry insulating material, such as a book, newspapers or rubber matting and use a long, low-conductivity object to push the power source away from the casualty, or to free the casualty's limbs from contact with the source.
