Shocks from household appliances are usually less severe but it can be much more damaging if the time
        duration or intensity of the voltage when in contact with body is more. It can cause seizures, muscle spasms,
        burns  and unconsciousness. It sometimes affects the central nervous system too.

        Some common electrical  ased ris  causing factors are:
           amaged extension cords or damaged electronic appliances

          Blocked electrical panels and heaters
          Overloaded circuits
          Loose connections

           resence of inflammable substances near electronic e uipments
          Old or poor wiring
          Thundering and lightening

        Countering Electric Currents

        In case of electric shock incidents  turn off the electric power by unplugging the appliances and flipping the
        circuit breaker.
           on t touch the in ured person if he or she is still in contact with the source.

          Call 112 or local emergency number if the source of burn is a high-voltage wire.
           se a non-conducting dry ob ect  i.e.  wood  plastic  etc.  to remove the source.

        Measures to Prevent Electrical Accidents

        Following are the measures that must be adapted to prevent electrical accidents:
           he users should inspect cord and plug connected e uipment  extension cords  electrical fittings  etc. for
           damages before each use.
           orn or damaged plugs should be discarded or repaired.  amaged and frayed switches and wires should
           be replaced.
          Switch off lights and all electrical connections whenever the o ce or work hours are over.

          Nails and staples should not be used in wires and cords.
           xtension cords or e uipment that is rated for the level of amperage or wattage should only be used for
           the respective devices.
           lways use the correct si e fuse.  eplacing a fuse with one of a larger capacity of wire can cause excessive
           currents in the wiring and ignite fire.

           lways use the receptacle boxes and ladders made with non-conductive materials  e.g.  fibre  glasses
           especially while working with or near electricity lines.
          Floors shouldn t be wet or damped as there is a higher risk of electric shock in such situations. Install
            round Fault  ircuit Interrupters   F Is  as they will interrupt the electrical circuit before the electrical
           current cause serious in uries.
           eat-emanating e uipment should be kept away from the electrical e uipment.

           ightening conductors should be installed at homes and o ce buildings.
           ircuits should not be overloaded and whenever there is an incident of electric shock  turn OFF the main
           connection.
