Benefits and dangers of electricity

 

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 :

 

1. We use it to operate some machines .

    

2. We use it to light houses , factories , streets ............etc .

    

3. 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 

    

   1. Do not place flammable materials ( as furniture , curtains , clothes , paper ) close to the electric materials that generate  heat ( as heater , iron , electric heater ) .

       

   2. Do not place several connections in the same socket .

       

   3. Do not insert a metallic object in the socket ( as nail , metallic wire or uninsulated screw driver ) .

       

   4. Do not touch the electric machine that are connected to the electric current with wet hand . 

       

   5. Do not play with the electric connections .

       

   6. Do not try to fix or clean any electric machine , while connected to the electric current .

       

   7. Do not place the electric wires extending on the ground as anyone can trip on them , while walking .

       

   8. Do not leave an electric machine connected with the electric current , while taking a bath .

       

   9. Do not leave the wires naked and not insulated .

       

   10. 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 .
