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.
