Only tree-trimming companies with OSHA qualifications may trim trees near power lines
Tree limbs that grow into power lines can cause fires, power outages, and damage to equipment or property. To increase safety and minimize outages, it is important to trim trees near power lines. However, this is a specialized task that requires qualified personnel.
OSHA recognizes three different qualification levels for line-clearance tree trimmers: unqualified employees, qualified employees, and line-clearance tree trimmers. Unqualified employees are those who are electrically unqualified and must maintain the minimum approach distance from power lines. Qualified employees must use their specialized skills and training to safely trim trees. Line-clearance tree trimmers are workers who have received specialized training to work within 10 feet of energized power lines and equipment.
Line-clearance tree trimmers must comply with OSHA's equipment and personnel requirements. They must be trained and certified in safety-related work practices and procedures, including emergency procedures. Additionally, they must follow medical and first aid provisions. Tree-trimming companies with OSHA qualifications are authorized to perform this specialized work and ensure the safety of their employees and the public.
It is important to note that customers can trim their own trees if they interfere with the service line from the utility pole to their home. However, it is recommended to notify the power company in advance so that they can temporarily remove the service line to allow for safe trimming.

Power companies send crews to trim trees near power lines to prevent outages
Power companies deploy crews to trim trees near power lines as a preventive measure against power outages. Tree limbs or other vegetation that grow into power lines can cause fires, damage equipment, and lead to power disruptions. To enhance safety and minimize outages, power companies routinely trim tree limbs and vines around power lines and utility poles.
Dominion Energy, for instance, follows the American National Standard for Tree Care Operations (ANSI 300) for tree trimming. This method, supported by arborists and tree care experts, helps direct future growth away from power lines while preserving the health of the trees. CPS Energy also follows a rigorous vegetation management schedule, addressing emergency, general, and planned tree trimming to minimize power outages.
In some cases, power companies will mark trees that require pruning or removal with paint or ribbons. They conduct inspections and, if necessary, return within a few weeks to perform vegetation work. This work includes pruning or cutting down trees to meet or exceed state vegetation and fire safety standards, as well as performing extra safety measures in high fire-threat areas.
The process of removing trees or trimming branches near power lines is highly dangerous and requires specialized knowledge and experience. Only tree-trimming companies that meet OSHA qualifications are permitted to perform this work near high-voltage power lines. These companies must comply with safety regulations and take the necessary precautions to protect workers and the public.
Property owners are generally responsible for maintaining the trees on their property to prevent interference with service lines. However, they are advised to hire professional tree-trimming services rather than attempting the work themselves due to the associated risks.

Property owners are responsible for trees and branches near wires on pole-to-building connections
Property owners are responsible for maintaining trees and branches that interfere with the service line, which is the electric line from a utility pole to the building. This means that property owners need to schedule and pay for the trimming or removal of trees that are threatening the lines. While property owners can trim their own trees, it is highly recommended to hire a qualified tree-trimming company to carry out the work due to the dangers associated with power and utility lines.
Tree limbs or other vegetation that grow on utility poles and into power lines can cause fires, power outages, and damage to equipment or property. Therefore, it is important for property owners to regularly assess the trees on their property and take necessary actions to prevent any potential issues. If a tree is found to be at risk of or in contact with power lines, it is crucial to contact the appropriate authorities or a professional tree removal company.
In the case of hiring a professional tree removal company, they will typically inspect the tree(s) and property to recommend the best method for removal. For instance, if a tree or limb cannot be lowered safely due to nearby objects, a crane may be necessary to remove the tree in a controlled manner. However, if there are power lines in close proximity, alternative removal methods may be required to ensure the safety of the workers and surrounding buildings.
To ensure safe and reliable power delivery, energy companies also play a role in trimming back trees and brush along power lines. This maintenance work is carried out following specific standards, such as the American National Standard for Tree Care Operations (ANSI 300), to direct future growth away from power lines and minimize potential disruptions. By working together, property owners and energy companies can maintain the safety and reliability of power lines, preventing accidents and reducing the impact of storms or natural disasters.

Power lines are dangerous and must not be touched
Power lines are often located near trees, and tree limbs or other vegetation that grow onto utility poles and into power lines can cause fires, power outages, and damage to equipment or property. Tree-trimming companies that meet OSHA qualifications are responsible for trimming trees away from power lines, complying with safety regulations and taking necessary precautions. This routine maintenance helps to ensure the safe and reliable delivery of power and reduces the risk of fire or other hazards caused by overgrown vegetation.
It is important to maintain a safe distance from power lines and any equipment or objects that may be in contact with them. If you are flying a kite, for example, it is crucial to do so in open areas away from electricity poles, power lines, and other obstacles. Kite strings can conduct electricity, so it is essential to release the string immediately if it gets caught in a power line. Similarly, when using a ladder, it is important to maintain a distance of at least 10 feet from power lines and only use a dry fiberglass or wooden ladder, never a metal one.
