3.3 HOT-LINE TOOLS
3.3.1 Minimum Working Distances. Hot-line tools shall be of sufficient length to
provide a minimum free insulated working distance between any part of the workmen
and the energized conductor or part being worked on as specified in

and the energized conductor or part being worked on as specified in
3.3.2 Care of Hot-line Tools. All hot-line tools when not in use shall be kept clean and
dry in an approved protective container. To prevent scratching while inserting and
removing hot-line tools stored in pipes, it is recommended that PVC pipes be used
rather that steel pipes.

3.3.3 Maintenance of Hot Sticks. Any splitting or deep cracks in the insulating
material, or cracks or other signs of weakness in metal parts shall be considered
sufficient reason for discarding the particular tool. FRP (fiberglass reinforced plastic)
portions of hot-stick tools shall be maintained in accordance with the manufacturer's
recommendations, The use of emery or carborundum papers, steel wool, or paint
brushes that have been used for other purposes shall NOT be used for refinishing

3.3.5 Testing Hot-line Tools. Insulated portions of hot-line tools shall be properly
tested for insulation value at least once a year and the results logged. Inservice
care, inspection, testing, and use shall be in accordance with the latest ASTM
(American Society for Testing and Materials) specifications or IEEE (Institute of
Electrical and Electronic Engineers) guidelines. In the absence of such
specifications and guidelines, inservice care, inspection, testing, and use shall be in
accordance with the recommendations by reputable tool manufacturers and
accepted practices among comparable electric utility organizations.
