In almost all occupations, electrical hazards exist in some form. Those hazards are multiplied for workers involved in cleanup and recovery efforts following major disasters. A particular life-threatening danger exists around downed and low-hanging electrical wires caused from high winds, ice storms, or other weather-related troubles.
Some Safety Tips:
- First, contact appropriate utility personnel.
- Do not assume that a downed conductor is safe simply because it is on the ground, or not sparking. Always consider all equipment, lines and conductors to be energized.
- The circuits don’t always turn off when a power line falls into a tree or on the ground. These downed power lines can kill you if you touch them, or the ground nearby.
- Low-hanging wires still have voltage potential even if they aren’t touching the ground.
- Never go near a downed or fallen electric power line. Always assume that it is energized. Fences, water pipes, bushes and trees, buildings, telephone/fiber optic cables, aluminum roofs, siding, sheds, etc., can also be energized by downed wires.
- Some sources that create electrical backfeed are: circuit ties/switch points, lightning, generators, and downstream events.
- Remember that electricity can travel away from its source.
- Don’t touch anything that is touching the wire.
- Never touch a person injured by a downed power line. Call 911 immediately.
- If you are in your car, stay inside and use a cell phone for help. Do not touch the outside of the car.
- Finally, never drive over downed power lines.

Sensible advice. I’d like to add that in case of downed power lines, it’s best to keep children indoors. They are curious at best and this curiosity might lead to touch or play with the downed wires. That, and their impression that they are young and are therefore invincible.
My boss just inquired about energized stuff. I will forward your info to him. Thanks! Check out my blog as well: http://beinginwardoutward.blogspot.com/
