TEXT

Electricity May Be Dangerous

Many people have had severe shocks from electric wires in a house. The wires seldom carry current at a higher voltage than 230, and a person who touches a bare wire or terminal may suffer no harm if his heart is strong and his skin is dry. But if the hand is wet he may be killed. Water is a good conductor of electricity and provides an easy path for the current from the wire to the body. One of the main wires carrying the current is connected to earth, and if a person touches the other with a wet hand, a heavy current will flow through his body to earth and so to the other wire. The body forms part of an electric circuit. The current contracts the muscles, and if the hand is holding the wire it may be quite impossible to open it so as to pull it away from the wire and break the circuit. The best thing that you can do for a person who is suffering from electric shock is first to switch off the current at once if possible and then to pull him away from the wires quickly. You should wear dry gloves while you are doing it or pull him off by some dry part of his clothes so as to avoid getting a shock yourself. Then give him artificial respiration at once. If this is done quickly, his life may be saved.

When we are dealing with wires and fuses carrying electric current it is best to wear rubber gloves. Rubber is a good insulator and will not let the current pass to the skin. If no rubber gloves can be found in the house, dry cloth gloves are better than nothing. Never touch a bare wire with the hand, and never in any circumstances, touch a water pipe and an electric wire at the same time.
