Tree branches touching power lines can cause fires, outages and electric shocks
Tree branches should never touch nearby power lines. When this happens, electricity can arc from the power line to the tree, causing a fire. This doesn't typically occur under normal conditions, but it is possible if there is a voltage surge on the power line, such as from a lightning strike. The fire risk is twofold: not only can arcing cause a fire, but a short circuit in a power line can also create sparks that could ignite a nearby tree.
Even without a fire, the electricity arcing from the power line to the tree can kill anyone in or near the tree. If you're standing too close to a tree that is touching a power line, electricity can jump from the tree to you, causing serious injuries or even death. Just touching a branch that is touching a wire can cause a fatal injury.
Trees that grow too close to electric lines can also cause power outages or momentary power interruptions when branches touch the lines. This can happen unexpectedly due to wind gusts or during pruning.
It is a homeowner's duty to maintain trees near power lines. Tree pruning typically costs between $75 and $1,500, while tree removal costs between $200 and $2,000. Dominion Virginia Power, which provides electricity to most of northern Virginia, recommends that you shouldn't plant trees of any kind within 15 feet of electric utility wires.

Trees conduct electricity due to their water content, which can lead to electrocution
Trees are not inherently good conductors of electricity, but their water content allows for the conduction of electricity. The water content in a tree's tissues enables electricity to travel from the branches to the ground. This means that if a tree touches a power line, electricity can flow through the tree and into anything that is touching the tree and the ground. This can lead to electrocution.
The risk of electrocution increases when trees or their branches are near power lines. A voltage surge on a power line, such as from a lightning strike, can cause electricity to arc from the power line to the tree. This can result in a fire and potentially electrocute anyone in or near the tree. Additionally, during storms, there is an increased chance of issues with a tree touching power lines. Strong winds can cause branches to unexpectedly make contact with electrical lines, or a power line may spark too closely to a tree, resulting in a fire.
Homeowners should be aware of the dangers associated with trees and power lines and take necessary precautions. It is recommended to maintain a safe distance between trees and power lines, with mature trees of 25 feet or taller being at least 25 feet away from overhead power lines. If a tree is too close to a power line, it is important to contact a professional for tree trimming or removal. Attempting to prune or remove a tree branch that is too close to a power line can be extremely dangerous and may result in serious injury or even death.
It is also crucial to keep children away from trees that are near power lines. Climbing or playing around such trees can lead to accidental contact with electric wires, often with fatal consequences. Even if branches are not touching the power lines, the additional weight of a child climbing the tree could cause the branches to make contact. Therefore, it is important to educate children about the dangers of playing near power lines and to supervise them accordingly.
In summary, trees can conduct electricity due to their water content, which can lead to electrocution if they come into contact with power lines. It is important for homeowners to be vigilant about maintaining a safe distance between trees and power lines and to seek professional help when needed to ensure the safety of their family and property.

Tree pruning near power lines is dangerous and should be left to professionals
Tree pruning near power lines is a dangerous task that should be left to professionals. The risks associated with trees near power lines increase exponentially, and horrific accidents can occur if the proper precautions are not taken.
Firstly, it is important to understand that trees can conduct electricity. While wood itself is not a good conductor, the water inside a tree's tissues allows electricity to travel from the branches to the ground. This means that if a tree's branches come into contact with power lines, electricity can arc from the lines to the tree, potentially causing a fire or delivering a fatal electric shock to anyone in or near the tree. Even if the branches are not touching the power lines, a strong gust of wind could cause them to make contact, or a person climbing the tree could bend the branches and accidentally make contact.
Additionally, attempting to prune trees near power lines can be extremely hazardous. It is easy for pruning tools, such as long-handled saws or ladders, to accidentally come into contact with the power lines, resulting in serious injury or even death. Professional tree service companies have the necessary training and equipment to perform these tasks safely. They are able to distinguish between dead and healthy branches and know how to keep branches from falling during pruning.
Furthermore, power lines can be damaged by tree branches rubbing against them, leading to short circuits and potential fires. Severe weather conditions can also cause trees to interfere with power lines, resulting in power outages and disruptions to essential services.
In some cases, utility companies may be responsible for trimming trees near power lines, and they often have professional line-clearing crews who can safely handle these tasks. It is always best to contact your local utility company or a professional tree-trimming service specializing in working around power lines. They will have the knowledge and experience to safely and effectively handle any tree-related issues near power lines.
