Tree Trimming & Removal Cheat Sheet (DRAFT) by [deleted]

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Introd­uction

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 AllTimes!

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., as 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.
