The inspection records shall provide an ongoing safety assessment of the equipment and be

used to predict repair-part replacement. All inspections shall be dated and initialed by the

inspector.

6.2.9

MECHANICAL ELEVATING AND ROTATING EQUIPMENT

The primary electrical safety concern is working in proximity to live and unguarded electrical

overhead lines by uninsulated equipment. Unless these lines are visibly grounded at the point of

work and the owner of the lines indicates that they are deenergized, barriers or insulating

protective material shall be installed to prevent worker contact with them. The following

clearances shall be maintained between equipment and electrical overhead lines:

1. Lines 50 kV or below: 10 ft between the lines and any part of the equipment or load

2. Lines over 50 kV: 10 ft plus 0.4 in. for every 1 kV above 50 kV.

In locations and situations where it is possible that the operator may have difficulty observing

that these clearances are being maintained, someone shall be designated to monitor the

clearances and provide the operator with timely warning before contact can be made. The use

of cage-type boom guards, insulating links, or a proximity sensor shall not alter the electrical

safety requirements of 29 CFR 1910.269(p)(4) and 1926.550, even if these devices are

required. (See Figure 6-2.)
