7.13.4 Working on Trees Near Energized Lines
Be aware that lines may not always be de-energized for tree trimming
operations. Review the rules for live-line safety and for climbing and
working on a pole especially in regard to being knowledgeable of the
energized lines in the area and the relevant dangers. Workers in trees
should use harnesses and safety straps. When working near energized
lines, arrange your safety line so that a slip or fall will carry you away
from the energized lines.
7.13.5 Climbing and Working on Trees
Climbing trees should be avoided unless ladders or aerial lift bucket
trucks will not provide the necessary access. Workers in trees should use
every precaution to prevent contact with aerial electric and telephone
wires, and damage thereto. Ensure that the following precautions are
126.96.36.199 Tree Climbers. If tree climbers are used, ensure the equipment is approved for
the bark thickness of the tree being climbed. Never use pole climbers.
a. Use a harness and safety strap or life line. Place the strap around a tree limb of
sufficient size to hold the worker's weight, but never around the tree limb being cut.
b. Do not stand on tree limbs too small to support your weight. Extreme care should be
exercised when working in trees that have brittle wood.
188.8.131.52 Tree Work. Before felling trees inspect tools to be used (such as ropes, tackle,
ladders, and chain saws) to ensure they are in proper condition.
a. Place signs warning pedestrian and vehicular traffic of the danger from work being
performed. Station flagmen where necessary.
b. Inspect each tree for possible dangers (conductors and fences) in the line of fall. Have
energized conductors de-energized if possible.
