With all the appliances, tools, cords and plugs we use in everyday life, it's important to know how to use them safely.
When you use a plug with three prongs, the third prong connects inside the outlet with a 'ground wire' which usually connects to a water pipe or a ground rod at the service panel. As a result, in a short circuit, electricity should flow to the ground instead of through you. Never remove a third prong.
Understanding how electricity works will enable you to use it safely around the home. Here are facts and tips that will help you avoid electrical hazards and injuries.
Electricity always seeks the shortest path to the ground. It tries to find a conductor, such as metal, wet sod, wet wood, water or your body. Your body is 70 percent water. So if you touch an energized bare wire or faulty appliance while you are grounded, electricity will instantly pass through you to the ground, causing a harmful or fatal shock.
The amount of electricity used by one 7.5-watt bulb on a string of holiday lights can kill you in a fraction of a second if it passes through your chest. Even if it isn't fatal, electrical shock can easily cause serious falls, burns, cuts or internal bleeding.
Most service panels have a main switch. Use it to cut all power when changing a fuse, or in case of fire or shock. If you don't have a main switch, turn off all circuit breakers. Don't tamper with your electric meter. You'll risk shock, explosion or fire.
Consider an inspection if:
A ground fault occurs when electricity travels outside an intended path, because of a frayed wire or faulty device, and tries to get to the ground by the shortest route. Touch that device, and you may become that route. Unless you have an outlet with a GFCI, you may be seriously shocked or burned.
