Working around or near electrical power lines is one of the most dangerous practices for crane operations. The OSHA requirements limit crane operations to a minimum clearance of 10 feet.
Cranes should not be used to handle materials or loads stored under electric power lines. In addition, operation of mobile cranes near de-energized electric power lines is not recommended until the following steps have been taken:
The power company or owner of the power line has deenergized the lines.
The lines are visibly grounded and appropriately marked at jobsite.
Durable warning signs are installed at the operator's station and on the outside of the crane identifying the clearance requirements between the crane/load and electrical power lines.
A qualified representative of the power company or owner of the electrical power line are on the job site to verify that the power lines have been de-energized or properly grounded.
