This section applies to work performed on exposed live parts (involving either direct contact or contact by means of tools or materials) or near enough to them for employees to be exposed to any hazard they present. - (2) Work on energized equipment . Only qualified persons must work on electric circuit parts or equipment that have not been deenergized under the procedures of WAC 296-[redacted postal code](2). Such persons must be capable of working safely on energized circuits and must be familiar with the proper use of special precautionary techniques, personal protective equipment, insulating and shielding materials, and insulated tools. ## (3) General requirements - high voltage lines . - (a) Minimum clearance . - (i) You must not perform any work, you must not pile, store, or otherwise handle any material, you must not erect or dismantle any scaffolding, commercial signs, or structures, nor must you operate any tools, machinery or equipment within the specified minimum distances from any energized high voltage electrical conductor capable of energizing the material or equipment; except where the electrical distribution and transmission lines have been deenergized and visibly grounded at point of work, or where insulating barriers not a part of or an attachment to the equipment have been erected, to prevent physical contact with the lines, you must operate equipment proximate to, under, over, by, or near powerlin…

If work is to be performed near overhead lines, you must deenergize and ground the lines, or provide other protective measures before work is started. If the lines are to be deenergized, you must make arrangements with the person or organization that operates or controls the electric circuits involved to deenergize and ground them. If protective measures, such as guarding, isolating, or insulating, these precautions must prevent employees from contacting such lines directly with any part of their body or indirectly through conductive materials, tools, or equipment. - (6) Unqualified persons . When an unqualified person is working in an elevated position, or on the ground, near overhead lines, the location must be such that the person and the longest conductive object he or she may contact cannot come closer to any unguarded, energized overhead line than the following distances: - (a) For voltages to ground 50kV or below--10 ft.; - (b) For voltages to ground over 50kV--10 ft. plus 0.4 inch for every 1 kV over 50 kV. - (7) Qualified persons . When a qualified person is working in the vicinity of overhead lines, whether in an elevated position or on the ground, the person must not approach or take any conductive object without an approved insulating handle closer to exposed energized parts than shown in subsections (3) and (4) of this section unless: - (a) The person is insulated from the energized part (gloves, with sleeves if necessary, rated for the voltage involved are considered to be insulation of the person from the energized part on which work is performed); or - (b) The energized part is insulated both from all other conductive objects at a different potential and from the person; or - (c) The person is insulated from all co…
