Electricity Safety

Electricity is so integrated into our daily lives that we often take the convenience it offers for granted. Though we have safe uses for it, electricity can become very dangerous if not used safely. Outlined below are all the things you need to watch out for to ensure electricity safety.

Basic Characteristics of Electricity

Electricity seeks the shortest path to the ground. When an object or person is too close to or comes in contact with a power line, the electricity travels at approximately 185,000 miles per hour through the person or object.

Electricity flowing through the human body can severely injure or kill a person. Electric power lines are not insulated like power cords used for appliances and other electric devices. Power lines have no protection when touched and should always be considered energized and very dangerous.

Overhead Power Lines

Substations and power lines are protected and secured for a reason. Never attempt to climb a fence to a substation or climb a utility pole. And remember that copper theft could cost you more than time in prison – you could be electrocuted while taking the copper and die.

When working around overhead lines, use extreme caution and ensure that you maintain at least a safe distance of 10 feet from any service or three-phase overhead line. Additional distance should be maintained from higher voltage lines. Electricity can arc to nearby equipment, even if it’s not directly touching lines. Because of this, always carry ladders and other equipment horizontally, not vertically. And, remember, you can always contact LCUB for additional assistance and advice if you will be working near overhead lines.

Underground Power Lines

Overhead power lines are easier to identify than underground. Especially in recent years, underground utilities have become increasingly popular in new commercial and residential development.

Even though you cannot see them, underground lines present the same safety issues as overhead lines and are just as dangerous. Any time you dig, excavate, or move earth, regardless of how small the job might be, contact Tennessee 811 before digging to have underground utility lines properly marked. Tennessee 811 is a FREE service that can be reached by dialing 811, calling (800) 351-1111, or submitting a ticket online through the Tennessee 811 website. Locators will also mark other underground utility lines, including gas and water, so you can complete your project safely.

Green transformer enclosures may be located in your subdivision or in commercial areas. While these structures are secured and are relatively safe, it’s important to never attempt to open the box and that children understand to leave them alone. Never plant shrubs or trees near underground transformers in attempt to landscape around or conceal the device. They must remain easily accessible by utility workers for routine maintenance and repair work to ensure your safety.

Around the House

Take these electricity safety precautions anytime you use an electrical device around the house:

• Never insert your finger or any other object into outlets. Take care to not touch any metal portion of a device you are plugging into an outlet.
• Limit the number of devices plugged into each outlet. Circuit overload can cause fires.
• Routinely inspect electrical cords and plugs for appliances to ensure they are not damaged. If it is damaged, do not use it and contact a licensed electrician if you need additional assistance or advice.
• Install outlet covers and protectors if small children are in your home.
• Do not remove ground pins (the third prong) from plugs. Always use a two prong adapter if your outlets do not have a ground pin.
• GFCIs (or GFIs) should be used in any area where water and electricity may contact one another. Routinely test GFCIs to ensure they work properly.
• Keep all appliances, radios, and any other electric powered device away from water.

Downed Power Lines

During emergency situations, downed power lines may be present. Always use extreme caution when approaching the scene of an emergency to ensure that you do not come into contact with any downed power line. Review the following safety tips to be more prepared if an accident or natural disaster occurs:

• Always assume that downed power lines are energized and dangerous.
• Never approach or touch any downed power line.
• Contact LCUB to report downed power lines.
• Never drive over downed power lines.
• If a power line falls over your car, stay inside and do not exit the vehicle, provided it is safe. If you must exit the car because of a fire or other impending emergency, try to jump completely clear of the vehicle to land on both feet. When landing, keep both feet together and shuffle until you are at least 10 feet away from the lines and vehicle.
• Do not try to help others near downed power lines. You will be unable to help them if you are electrocuted in the process. Leave the rescue efforts to emergency personnel and professionally trained crew members.
