Amend Section 2940.2 to read:

2940.2. Clearances.

(a) No employee shall be permitted to approach or take any conductive object without an approved insulating handle closer to exposed energized parts than shown in Table 2940.2 unless:
(1) The employee is insulated or guarded from the energized part (gloves or gloves with sleeves rated for the voltage involved shall be considered insulation of the employee from the energized part), or
(2) The energized part is insulated or guarded from the employee and any other conductive object at a different potential. (b) When performing work with live line tools, minimum clear distances in Table 2940.2 shall be maintained. Conductor support tools, such as link sticks, strain carriers, and insulator cradles, shall be permitted to be used provided that the clear insulation is at least as long as the insulator string or the minimum distance specified in Table 2940.2 for the operating voltage.

TABLE 2940.2-1


NOTE: Above 242 KV the minimum working distance and the minimum approach distance shall be permitted to be reduced provided that such distances are not less than the shortest distance between the energized part and a grounded surface.

Table 2940.2-2

Note 1: The distances specified in this table may be applied only where the maximum anticipated per-unit transient overvoltage has been determined by engineering analysis and has been supplied by the employer. However, if the transient overvoltage factor is not known, a factor of 1.8 shall be assumed.
Note 2: The distances specified in this table are the air, bare-hand, and live-line tool distances.

Amend Section 2940.6 to read:

2940.6. Tools and Protective Equipment.
(a) Rubber Insulating Equipment
(1) Rubber iInsulating equipment designed for the voltage levels to be encountered shall be provided and the employer shall ensure that they are used by employees as required by this section. This equipment shall meet the electrical physical requirements contained in the standards as shown in Appendix C.
(2) Whenever rubber gloves are used, they shall be protected by outer canvas or leather gloves. This equipment shall meet the electrical physical requirements contained in the standards shown in Appendix C.
(3) Insulating equipment fabricated of material other than rubber shall provide electrical and mechanical protection at least equal to that of rubber equipment.
(4) The employer is responsible for the periodic visual and electrical re-testing of all insulating gloves, sleeves and blankets. Effective February 23, 1998, t The following maximum re-testing intervals in accordance with the listed ASTM standards, which are hereby incorporated by reference, shall apply:


(In-service care)

ASTM STANDARD                                                                                                  MONTHS
Standard Specification for In-Service Care of
Insulating Gloves and Sleeves, ASTM F 496-95a 97                                                      6
Standard Specification for In-Service Care of
Insulating Blankets, ASTM F 479-95                                                                          12
Standard Specification for In-Service Care of
Insulating Line Hose and Covers, ASTM F 478-92

(5) Gloves, sleeves and blankets shall be marked to indicate compliance with the re-test schedule and shall be marked with either the date tested, or the date the next test is due.
(6) When not being used, insulating gloves and sleeves shall be stored in glove bags or suitable containers. Insulating blankets shall be stored in a canister or other means that offers equivalent protection.
(7) Insulating equipment shall be stored away from direct sunlight, steampipes, radiators and other sources of excessive heat and shall be protected from physical damage. Gloves, sleeves and blankets shall not be folded while in storage; however, blankets shall be permitted to be rolled for storage.
(8) Insulating equipment shall be visually inspected for defects and damage, and shall be cleaned prior to use each day.
(9) Rubber gloves shall be air and water tested at the beginning of each work period and at any other time when the glove’s condition is in doubt. As a minimum, tThe gloves shall:
        (A) Be visually examined over their entire inner and outer surface for any defects, i.e., burns, cuts, cracks, punctures                 and weak spots; and
        (B) Have the cuff stretched to detect abrasions and weak spots.
(10) Insulating equipment found to be defective or damaged shall be immediately removed from service.

 Amend Section 2941 to read:

2941. Work on or in Proximity to Overhead High Voltage Lines.

Overhead High Voltage Lines.

(h) Grounding De-Energized Conductors or Equipment. Any exposed ungrounded conductors or equipment not worked upon in accordance with the provisions of subsections (f) above, shall not be worked upon until the following provisions are complied with:
(1) Conductors or equipment to be grounded are clearly identified and isolated from all sources of voltage.
(2) Notification has been obtained from the designated employee that all switches or other points of isolation through which electric energy may be supplied to the conductors or equipment to be worked on have been opened and are plainly tagged indicating that employees are at work, and where the design permits, they have been rendered inoperable.
(3) When more than one independent crew requires the same conductors or equipment to be de-energized, a tag for each such independent crew has been placed at the switch(s)or other point(s) of isolation, except that where clearances for such independent crews are controlled by a designated authority having immediate jurisdiction over the conductors or equipment involved, only one tag need be installed at each switch or point of isolation.
(4) A test has been conducted to insure that conductors or equipment have been de-energized.
(5) The conductors or equipment shall be grounded and short-circuited.
(6) Suitable grounding devices shall be used. They shall be first connected to a ground before being brought into contact with any de-energized conductor or equipment to be grounded. The other end shall be attached and removed by means of insulated tools or other suitable devices. When removed they shall be removed from all circuit conductors or equipment before being disconnected from ground.
(7) There shall be a minimum of one ground on the conductors or equipment being worked on:
(A) between the place where the work is being done and each possible source of supply, or
(B) at each work location.
(8) One of the grounding devices shall be visible to at least one member of the crew unless one of the grounding devices has all of its component parts at least 15 feet above ground level to prevent tampering.
(9) Grounds shall be permitted to be temporarily removed for test purposes and extreme caution shall be exercised during test procedures.
(10) Grounding devices shall be capable of conducting the anticipated fault current and shall have a minimum conductance of No. 2 AWG copper.
NOTE: Guidelines for protective grounding equipment are contained in American Society for Testing and Materials Standard Specifications for Temporary Grounding Systems to be Used on De-energized Electric Power Lines and Equipment, ASTM F 855-97.
(11) Upon completion of work on grounded conductors or equipment, the employee in charge of each independent crew shall determine that all employees in the crew are clear, and shall report to the designated authority that all tags protecting the crew may be removed. Prior to the energizing of the conductors or equipment, the employer shall ascertain that all employees are clear and all grounds are removed.
(12) Temporary protective grounds shall be placed at such locations and arranged in such a manner as to prevent each employee from being exposed to hazardous differences in electrical potential.
