Outdoor Electrical Safety

Powerlines/Substations/Transformers

Electrical currents exist in places other than electrical outlets. There are a number of electrical dangers to be aware of in the outdoors, including lightning and power lines. To avoid injury, pay attention to your surroundings both indoors and outdoors.

  • Check for power lines in trees before using a ladder (even a wooden ladder) or scaffolding.
  • Check for power lines running through or near trees before trimming branches. Call Delmarva Power to trim branches that interfere with power lines.
  • Install antennas away from power lines.
  • Never go near or touch a fallen power line. Call Delmarva Power to report the location of the downed line at one of the following numbers:
    • New Castle County (Delaware); Cecil & Harford Counties (Maryland
      1-800-898-8042
    • Kent & Sussex Counties (Delaware); Eastern Shores of Maryland 1-800-898-8045
  • Do not throw anything over or at a power line, substation, or transformer.
  • If a power line falls on your car, stay in the car and try to drive away. Do not touch the metal parts of the car. If you can’t drive, wait for help. Call 911 for assistance if you have a cellular phone. If you must get out of the car, jump clear without touching the car and the ground at the same time.
