National Electrical Safety Month: Power Lines on Trees

Before you break out the shears, there are a few safety tips to keep in mind when trimming your trees and shrubs!

Power lines on trees

Some would say that spring is simply the most delightful time of the year here in Seattle (and frankly, it’s hard to disagree!). As trees and shrubs begin to blossom, it may be tempting to go outside and start trimming. Before you break out the shears, there are a few safety tips to keep in mind. We reached out to City Light’s arboriculturist and resident tree buff Heidi Asplund for tips on how to keep your pines, maples and family safe around power lines.

Here are a few of Heidi’s handy safety tips:

  • Keep kids safe – make sure their play activities don’t include trees near power lines. Trees touching power lines may become energized, causing a dangerous situation for kids climbing in them, swinging in them or otherwise playing in them.
  • Heading out into your yard to prune trees and shrubs? Make sure you, your tools and the branches you want to prune are a safe distance from power lines. If the branches you’re pruning or your tools make contact with a power line, you could receive an electrical shock injury which can result in significant burns or even death. Branches, tools and you should be at least 10 feet from distribution power lines and 21 feet from high voltage transmission lines.
  • See a tree or branch touching a power line? Trees touching power lines may be energized and safety hazards. If you’re not sure whether a tree could cause an issue, give us a call and we’ll check it out!
