Tree Trimming & Removal
Safety
Assume that All Power Lines Are Energized!
- Contact the utility company to discuss de-energizing and grounding or shielding of power lines.
- All tree trimming or removal work within ten 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.
Stay Alert at All Times!
- 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, etc., recommended in the equipment manufacturer’s operating manual.
- Determine the tree’s felling direction. Address forward lean, back lean, and/or side lean issues.
- Determine the proper amount of hinge wood to safely guide the tree’s fall. 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.
