Wood, paper, and some chemicals can catch fire from just a spark. Second, electricity can burn, shock or even kill you, depending on the strength of the shock. Third, when you are shocked, your muscles can contract violently, causing serious falls or other accidents. Fourth, when electric equipment is not turned off after use, the next person to use it may not know the power is on. That person can be shocked or injured.
Electricity always tries to reach the ground.
Excellent conductors include people, weather, damp floors or metal. Electricity cannot flow easily through insulators like plastic, rubber boots, dry wood or glass. Protect yourself by following these important rules for electric safety. Don't use any appliance or machinery while you are touching metal or anything wet. Unplug machinery and appliances before cleaning, inspecting, repairing or removing anything from them.
