Before assembly or disassembly of a crane the employer must determine if it could come within 20 feet of a power line (up to 350 kV). If so the employer must take one of the following actions (a) Confirm with the power company that the line is deenergized and visibly grounded at the worksite. (b) Make sure no part gets within 20 feet of the power line.
