Check for frayed or cracked electrical cords, and replace them.
Make sure that outlets and extension cords are not overloaded. Either change the cord to a higher rated one or unplug some of the appliances.
Check to see that all lamps and light fixtures are outfitted with bulbs of the correct wattage; this will prevent overheating which could lead to a fire.
Make sure that all fuses are the correct size for the circuit. The wrong size fuse can create a serious fire hazard.
If an appliance has repeatedly blown a fuse, tripped a circuit breaker, or shocked you, unplug it and have it repaired or replaced.
If an outlet or switch is unusually warm or hot to the touch, an unsafe wiring condition could exist. Have it checked by an electrician as soon as possible.
Always follow the manufacturer's instructions and safety precautions for all home appliances.
Have earthing installed in your house.
First Aid For Electric Shock
If someone gets an electric shock, here is what you can do.
The victim usually gets stuck to the source of the electricity, and it is important that you first separate him from the electrical source.
Turn off the power supply switch and disconnect the plug. It's best to simply turn off the main power supply or pull out the fuse. Often, simply turning off the switch may not stop the flow of electricity.
In certain circumstances it may be quicker to simply pull the victim away from the electrical source.
Do NOT touch the victim with your bare hands, or the electric current will pass through you as well.
If you are barefoot, stand of some clothes or any hand non-conductive material like wood or paper. Make sure you are not standing on anything that is wet.
Throw a blanket over the victim and try to separate him from the source. Make sure you don't touch him though. You can also use dry, nonconductive material such as a wooden broom handle or a chair to separate the victim from the live current
Once the victim is separated, check to see if he is breathing. If breathing has stopped or seems slow, administer articificial respiration immediately.
Let his head be slightly lower than the rest of the body, and raise his legs.
Cover the victim with a blanket.
Move the victim as little as possible. He may have suffered injuries to his spine and neck.
If the victim has a burn, remove the clothing from the burned area (unless it's stuck to the skin) and rinse it in cool, running water. Cover the burn with a dressing.
Don't apply ice or any other ointment or cotton dressing to the burn.
Call for emergency medical attention as soon as possible.
