If you have further concerns about a tree's safety, contact an International Society of Arboriculture.
Feb 26, Continually trimming trees that are close to a high-voltage transmission line is not as safe as removing them. Trimming trees near high-voltage, energized power lines is dangerous work that can be deadly. Ina WAPA line worker was killed while trimming trees. In more severe cases, a limb or entire tree can break the power line, causing a widespread outage.
Damage to power lines by trees or tree limbs can threaten the safety of your employees as well as the public. Line damage could result in injury or death due to electric shock or electrocution. Dead trees present a significant threat to our power lines. That's why it's necessary to remove the portion of the tree that may hit the line, which can sometimes mean taking the entire tree down. Any debris resulting from the partial or full take down of a dead tree is the property owner's responsibility.
