I wasn't able to find specific documentation on electrical rough-in safety procedures and inspection requirements in our current safety knowledge base, but here are industry-standard safety guidelines:

When working with or around electricity, employers must ensure that workers do not work near any energized electrical conductor or equipment unless adequate protective guards or equipment are provided and workers are using adequate protective equipment. Employers must ensure that workers in a manhole or tunnel have continual communication with another competent worker when working on any energized electrical conductor or equipment having a potential in excess of 600V. Manholes containing energized electrical conductors or equipment must also have approved insulated mats or platforms to protect workers while at work. [1] [1] [1]

Before working on electrical conductors or equipment that must be de-energized, the worker in charge must open, lock, and tag any switching device which supplies electrical energy to the conductors or equipment being handled. After work has been completed on de-energized electrical conductors, utility lines, or equipment, the worker in charge of the work shall determine that all workers are clear of work areas and authorize the energizing of the electrical conductors, utility lines, or equipment. [1] [1]

When operating equipment near power lines, workers must maintain specific minimum approach distances. For alternating current, the minimum clearance distance is 10 feet for voltages up to 50kV, 15 feet for voltages over 50kV to 200kV, 20 feet for voltages over 200kV to 350kV, 25 feet for voltages over 350kV to 500kV, 35 feet for voltages over 500kV to 750kV, and 45 feet for voltages over 750kV to 1000kV. [2] [2] [2] [2]

Portable electric equipment should be handled in a manner that does not cause damage, and flexible electric cords connected to equipment should not be used for raising or lowering the equipment. Flexible cords should also not be fastened with staples or hung in a way that could damage the outer jacket or insulation. Portable cord and plug-connected equipment and flexible cord sets should be visually inspected before each shift for external defects or evidence of possible internal damage. [3] [3]

In proximity to electrical equipment operating at over 600 V that may be accessible to workers, notices reading "Danger-High Voltage" must be placed in prominent positions. [1]
