You should know that electricity is very important in our life . Everyone needs electricity . We can not imagine our life without it , So it also has benefits and dangers . We must know how to deal with it .
Benefits of Electricity :
We use it to operate some machines .
We use it to light houses , factories , streets ............etc .
You should know that we use it to cook food and preserve it cold .
Dangers resulted from the improper use of electricity
Direct injuries include Fires resulting from electricity , The electric shock and Burns resulting from the electric current .
Indirect injuries like injuries that result from falling from the top of a ladder due to an electric shock .
Electric fires occurs due to the increase in the temperature of the electric machines .
Electric shock occurs due to passing the electric current through the human body .
Electric burns are burns that result from electricity and cause the damage of the body tissues .
Important precautions in dealing with electricity
Do not place flammable materials ( as furniture , curtains , clothes , paper ) close to the electric materials that generate heat ( as heater , iron , electric heater ) .
Do not place several connections in the same socket .
Do not insert a metallic object in the socket ( as nail , metallic wire or uninsulated screw driver ) .
Do not touch the electric machine that are connected to the electric current with wet hand .
Do not play with the electric connections .
Do not try to fix or clean any electric machine , while connected to the electric current .
Do not place the electric wires extending on the ground as anyone can trip on them , while walking .
Do not leave an electric machine connected with the electric current , while taking a bath .
Do not leave the wires naked and not insulated .
To prevent inserting another body in the socket , You must place a piece of plastic in it .
The human body is a good conductor of electric current , because water is 70 % of the human body . The electric shock happens when your body is a part of a closed circuit , where the electric current flows from a part of of your body and comes out from another part . The human body is more exposed to electric shock when it is wet . In many cases , electric shock causes death . 
Man made the electric cables ( wires ) from copper which is an electric conducting material . Electricity reaches our houses and factories from electric power stations through metallic cables . These cables are hanged on insulating materials to prevent electric current from reaching the towering poles .
