Power Line Safety

Always use extreme caution near wires and power lines—for your own safety, assume they are live and deadly.

If you see a downed line, keep everyone away and report it to us at 1-800-465-1212 immediately. Repairing downed power lines can be dangerous work, so please drive carefully when you spot our repair crews on the road.

Downed Power Lines

If you see a downed power line, NEVER:

  • Touch downed power lines or anything coming in contact with fallen lines
  • Walk beneath overhead equipment, lines, or wires near a downed line
  • Touch someone who is being electrically shocked
  •  Handle or cut utility poles
  • Burn old poles as firewood—this will expose you to the chemicals used to treat and preserve them

Tree Trimming

Diseased or overgrown trees can damage power lines and lead to outages. To ensure reliable service, we will visit your neighborhood every five to seven years to trim around high voltage electric wires. We do not trim outside of our schedule unless there is a significant hazard affecting those wires.

Homeowners are responsible for trimming tree branches near the low voltage service drop to their individual home. Many people choose to remove these trees to reduce the risk that their tree may damage their home or electric service. To learn more how to manage the trees that grow around the distribution lines that power your homes and businesses, read our brochures on our trimming policies, planting near electric lines, and how to combat tree-killing insects.  

Vegetation Around High Voltage Lines

Power Transmission Lines

Unregulated tree and vegetation growth near high-voltage transmission lines can cause service interruptions, wildfires, and electrocution. National Grid has established “rights of way” around these lines where vegetation is strictly regulated to ensure public safety. If there are transmission lines on your property, you can learn more about our policies and your responsibilities in our Landowners Along Our Transmission Lines brochure or Pennsylvania State's Research on Vegetation Management on ROWs.
