7.4.14 PLACING OF INSULATING GOODS ON CONDUCTORS
When workers are about to begin work that requires the use of rubber goods, they should climb or
raise the bucket to a position just below the first line of conductors. When climbing they should then
determine their working position and what lines and other conductors should be covered. They
should then request the required rubber goods. Before proceeding further, the workers shall put on
the rubber gloves and leather protectors and make certain that they are in good order. Rubber goods
shall be raised in a secure manner.
As the workers ascend to their working position, they shall cover all conductors which provide a
hazard. This should be done from below whenever possible. At no time shall workers pass through
energized equipment before it is covered with rubber goods (line guards). All conductors and grounds
adjacent to working space shall be considered, including those near any possible change of position
that may be necessary. When line hose is applied to vertical or sagging wires, it should be fastened
to the line to prevent its slipping from position. When blankets are used for covering items such as
dead ends, potheads, secondary racks, and transformers, they should be secured by wooden or plastic
clamp pins or tie thongs. After the protective equipment has been placed, care should be taken to
prevent damage to the rubber from tie wires, spurs, or other objects.
7.4.15 REMOVING INSULATING GOODS FROM CONDUCTORS
When the job is completed, the protectors should be removed in the reverse order of installation.
Remote conductors are removed first and the wires nearest the workers last. After being detached,
the equipment should immediately be lowered to the ground.
7.4.16 CLEANING AND INSPECTING
After the rubber goods have been lowered to the ground, they should be cleaned and visually
inspected before being placed in the carrier compartments of the truck.
7.5 PROTECTIVE GROUNDING OF LINES AND EQUIPMENT
Grounding is the most effective way of protecting electrical workers from electric shock. That is why
it is important to ensure that all deenergized lines and equipment are grounded. (See Sections 4.5.2,
7.5.3, Figure 7-2, 29 CFR 1910.269(n), 1926.954, and IEEE 1048-1990, "IEEE Guide for Protective
Grounding for Power Lines.")
7.5.1 PURPOSE
This section provides information concerning protection for workers repairing, servicing, or working
on high-voltage power lines. (See 29 CFR 1910.269(n), 1926.954, and ASTM F-855.)
