Power distribution lines are a major hazard in electrocution of equipment operators. When
power lines are in the area, care must be taken. Below are just a few of the many items to
check for crane operation.
If any part of the crane operating within the work zone, could get within 20 feet of a power line
(50 feet if >350kV), then one of the following 3 requirements must be met.
1) Contact the utility owner/operator and obtain documentation that the power line has been
de-energized and visibly grounded at the worksite.
2) Ensure that no part of the equipment (crane, load line, and load) operates within 20 feet of
the power line and implement the Encroachment Prevention Plan Checklist (Attachment A);
or
3) Determine the minimum approach distance allowed under the Minimum Clearance
Distances Table and determine the lines voltage. If any part of equipment operating within
its maximum working radius in the work zone could get closer to the minimum approach
distance then implement the Encroachment Prevention Plan Checklist (Attachment A).
