§ 39.363. General requirements.
(a) Touching live parts. No employe should touch with bare hands at the same time two parts at different potential; nor should he touch with bare hands even a single exposed ungrounded live part at a dangerous potential to ground unless he is insulated from other conducting surfaces, including the ground itself, and stands on insulating surfaces.
(b) Wire insulation. Employes should not place dependence for their safety on the insulating covering of wires. Precautions in this section for handling live parts shall be observed in handling insulated wires. Insulation on a wire may look perfect, but it frequently cannot be relied on to prevent shock.
(c) Exposure to higher voltages. Every employe working on or about equipment or lines exposed in overhead construction to voltages higher than those guarded against by the safety appliances provided should, as far as practicable, assure himself that the equipment or lines worked on are free from dangerous leakage or induction or have been effectively grounded.
(d) Cutting into insulating coverings of live conductors. The following precautions should be observed:
(1) When the insulating covering on live wires or cables is cut into, the employe should use a suitable tool. While doing such work suitable goggles should be worn to protect the eyes. Insulating gloves should be worn to protect the hands.
(2) When metal sheathing is necessarily removed from cables it should be done with special tools which will not injure the insulation. The sheathing should be so cut as to leave enough exposed insulation after the conductor has been bared to avoid arcing over between the conductor and the sheath. If the cable consists of more than one conductor, similar exposed insulating surfaces should be left for each conductor, using insulating separators between conductors, if necessary.
(3) Insulating devices, such as wood separators, and the like, should be examined to eliminate conducting dust or chips, sharp edges, or nails, which may defeat the purpose for which the devices are intended.
