physical condition of the pole has been surveyed. Plan
your route to the victim now. To be on the safe side
assume the pole is energized; unless confirmed de-
energized. Leap onto the pole. No part of your body
should touch the pole and the earth at the same time.
This prevents your body from providing an alternate
path for the electricity. Remember, don't take chances
and become a victim also.
CLIMB TO RESCUE POSITION. Lay out the
rescue rope and attach one end to a loop of your body
belt. While climbing to the rescue position, be sure to
climb carefully and belt in at a safe position. Clear the
victim from energized conductors using rubber goods
or hot sticks, then reposition yourself and determine
the victim's condition. Slightly above and to one side is
normally best for checking and working with the victim.
A safe and easy method used to lower the victim to
the ground is shown in figure 4-81 and requires a pulley
line or a handline attached to a crossarm and tied off
around the victim's chest. The knot should be in front of
the victim, close to one armpit. lie three half-hitches,
and snug the knot so that the rope rides high on the
victim's chest Take up the slack, cut the victim's safety
strap, and slowly lower him or her to the ground.
MAINTENANCE OF POWER
The elements, accidents, and willful vandalism are
the causes of most damage to power distribution

equipment. To repair these damages, the lineman
requires experience, a total commitment to safety, and
the knowledge to accomplish repairs to the system as
quickly and economically as possible.
MAINTENANCE OF POLES, TIMBERS,
The maintenance required on the poles, timbers,
and crossarms in a power distribution system is
minimal. Normally, this equipment lasts for a period of
20 years or more. The following problems may occur,
however, and create a need for maintenance action:
A pole can settle and require straightening.
Wood can shrink and cause all hardware to
become loose and require tightening.
WOOD POLE MAINTENANCE
Wood poles are treated with preservatives to
prevent decay, but small organisms, insects, and fungi
all contribute to the breakdown of the wood
preservatives. The life of a pole can be extended by
inspections and treatment, when necessary, to stop pole
The inspection would normally include sounding
the pole by hitting it with a hammer from belowground
level to approximately 6 feet above ground to determine
obvious defects. Also the pole is bored to determine the
presence of internal voids. Poles with internal decay
can be treated with insecticides. External decay is
removed, and the area is treated with preservatives and
wrapped with a moisture-proof barrier. Poles weakened
excessively by internal or external decay must be
reinforced or replaced.
