Tree Trimming and Removal

Safe Work Practices

  • Assume all powerlines are energized.
  • Contact the utility company to discuss de-energizing and grounding or shielding of power lines.

  • All tree trimming or removal work within 10 feet of a power line must be done by trained and experienced line clearance tree trimmers.

  • A second tree trimmer is required within normal voice communication range.

  • Line-clearance tree trimmers must be aware of and maintain the proper minimum approach distances when working around energized power lines.

  • Use extreme caution when moving ladders and equipment around downed trees and power lines.

  • Do not trim trees in dangerous weather conditions.

  • Perform a hazard assessment of the work area before starting work.

  • Eliminate or minimize exposure to hazards at the tree and in the surrounding area.

  • Operators of chain saws and other equipment should be trained and the equipment properly maintained.

  • Use personal protective equipment such as gloves, safety glasses, hard hats, hearing protection, recommended in the equipment manufacturer’s operating manual.

  • Determine the felling direction of the tree. Address potential problems of forward lean, back lean, and/or side lean.

  • Determine the proper thickness of hinge wood to guide the tree’s fall safely. Provide a retreat path to a safe location.

  • Inspect tree limbs for strength and stability before climbing.

  • Tree trimmers working aloft must use appropriate fall protection.

  • Do not climb with tools in your hands.

  • If broken trees are under pressure, determine the direction of the pressure and make small cuts to release it.

  • Use extreme care when felling a tree that has not fallen completely to the ground and is lodged against another tree.

  • Never turn your back on a falling tree.

  • Be alert and avoid objects thrown back by a tree as it falls.
