Utility Line Clearance Arborist Training

Utility Line Clearance Arborist Training

Become a Utility Line Clearer / Arborist

Professional, trained arborists, know how to properly maintain trees for the safety of the public and the health of the tree. Their focus is to reduce the fire hazard caused by trees, branches or other debris coming in contact with energized power lines using safe work practices. Arborists have the knowledge and understanding of trees and shrubs common to their location. This knowledge helps them assess the condition of the trees, provide a diagnosis for potential diseases, and offer their recommendations on how to properly care and maintain the tree.

Course Details


The skills that the Utility Line Clearance / Arborist trainees receive, provide knowledge in safe tree work practices, tree identification and biology, pruning, trimming and removal techniques and the ability to work as a member of a tree care crew using equipment such as chippers, chainsaws, ropes, and bucket trucks to accomplish their job. They perform pruning, trimming, removal and clearing of trees or brush around electrical power generation, transmission or distribution lines or equipment on behalf of an organization that operates, or that controls the operation of those lines and equipment. This requires the Utility Line Clearance Arborist to be familiar with special techniques and hazards involved in line-clearance tree trimming to prevent contact with energized lines by themselves, their equipment, or by the trees they maintain. This requires special training as outlined by OSHA.
