When outside, stay at least 10 feet away from downed power lines and be alert to the possibility that tree limbs or debris may hide an electrical hazard. Treat all downed or hanging power lines as if they are energized. Lines do not have to be arcing or sparking to be live. Warn others to stay away, and contact your local electric cooperative.
Do not attempt to move downed power lines with other objects, and do not touch objects or puddles of water in contact with those lines. Make sure children are aware of these hazards as well.
After a storm, keep in mind:
• If you find yourself too close to a downed power line, shuffle away from it in small steps, with your feet together and touching the ground at all times.
• Don’t enter seriously damaged buildings and avoid using matches and lighters in case of gas leaks. Never attempt to turn off power at the breaker box if you must stand in water to do so.
• If you are driving and come upon a downed power line, stay in your vehicle, warn others to stay away. Never drive over a downed line; it could pull down poles and other items along its path.
• Never step into a flooded basement or other area if water is covering electrical outlets, appliances or cords. Never touch electrical appliances, cords or wires while you are wet or standing in water.
• If you use a portable generator, be sure a transfer safety switch has been installed, or connect appliances directly to the generator. This prevents electricity from traveling back through the home to power lines — what is known as “backfeed.” Backfeed creates danger for anyone near lines, particularly crews working to restore power.
