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.
