Section R. 408.41969 - Hot sticks

Rule 1969.

(1) A hot stick and any tool attached to it shall be clean and inspected for damage before use.
(2) A hot stick that has been damaged shall not be used until replaced or repaired by a knowledgeable employee or an outside service and tested to meet the requirements of subrule (3) of this rule.
(3) A hot stick shall not be used unless it has been certified and labeled by the manufacturer to meet the following standards:
(a) Fiberglass, 100,000 volts per foot of length for 5 minutes, or any equivalent test.
(b) Wood, 75,000 volts per foot of length for 3 minutes, or any equivalent test.
(4) A hot stick shall be stored in a manner to protect it from damage. A hot stick made of wood shall be protected from moisture.
(5) A hot stick shall not be used in excess of the rated capacity certified by the manufacturer.
(6) The minimum working distance and minimum clear hot stick distances prescribed in table 1, when using live-line tools, shall not be violated.
(7) The minimum working distance for live-line bare-hand technique prescribed in table 2 shall not be violated.
