• 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.
