ISA Certified Arborist has proven their knowledge about commercial or municipal arboriculture. However, through the execution of their tree trimming and pruning they can be in proximity to energized power lines. The UVMA would encourage any arborist that works on trees that can contact a power line or other energized electrical equipment to first check with the local utility to confirm what the rules and minimum tree to line (conductor) clearances are in that jurisdiction.
It is vitally important that arborists carefully consider the tree to energized line clearances and if there is ANY doubt about the ability of the tree to contact the conductor to cease work immediately and call the utility.
Only certified utility arborists can work on trees in close proximity to energized power lines and even then there are strict limits of approach for various situations.
Be wise and check with your utility.
Work safely.
