ELECTRICAL HAZARDS

The following guidelines must be followed to prevent accidental contact with overhead electrical conductors and/or communication wires and cables. (Ref. ANSI Z133.1-2000)

WORKING IN PROXIMITY TO ELECTRICAL HAZARDS

An inspection shall be made by a qualified arborist to

determine whether an electrical hazard exists before climbing, or otherwise entering, or performing work in or on a tree.

Only qualified line-clearance arborists or qualified line-

clearance arborist trainees shall be assigned to work

where an electrical hazard exists. Qualified line-clear-

ance arborist trainees shall be under the direct supervi-

sion of qualified line-clearance arborist.

A second qualified line-clearance arborists or line-clear-

ance arborist trainees shall be within vision or voice communication during line-clearing operations aloft when line-clearance arborists or line-clearance arborist trainees must approach closer than 10 feet (3.05 me- ters) to any energized electrical conductor in excess of

750 volts (primary conductor) or when:

1.Branches or limbs being removed cannot first be cut (with a pole pruner/pole saw) to sufficiently clear electrical conductors, so as to avoid contact.

2.Roping is required to remove branches or limbs from such electrical conductors. This does not ap- ply to individuals working on behalf of, or employed by, electrical system owners/operators engaged in line-clearing operations incidental to their normal occupation.

Qualified line-clearance arborists and line-clearance arborist trainees shall maintain minimum approach dis- tances from energized electrical conductors in accor- dance with Table 1.

All other arborists shall maintain a minimum approach distance from energized electrical conductors in accor- dance with Table 2.

Branches hanging on an energized electrical conductor shall be removed using non-conductive equipment.

Table 1 – Minimum approach distances from energized conductors for qualified line-clearance arborists and qualified line- clearance arborist trainees.
