Base of Pole: Telephone Plant Repairs
Examine the pole for potential electrical hazards such as a vertical power
ground wire, vertical metallic power conduit, street light fixture, power
company primary disconnect hardware, or other foreign metal objects. Also,
observe the pole and adjacent spans for such hazards as improper clearance
from power conductors or equipment, dangling power wires, inadequate
clearance on pole-to-pole guys from power wires or energized attachment,
etc. If none of these is present, the pole may be climbed providing no other
hazard is evident.
If a vertical power ground wire is present, make a voltage test of the wire
before climbing or working on the pole. If a vertical metallic power conduit or
other power company hardware extends to the base of the pole, make a
voltage test before climbing or working on the pole. If the ground wire is
broken, test the portion going up the pole unless the break exists above the
telephone space. Do not attempt to test a broken ground wire or fixture in
the power company's space (40 inches or more above the highest telephone
attachment). Refer to your company's safety procedures.
If the Voltage Detector does not indicate a hazardous voltage, poles carrying
vertical power ground wires may be climbed. Care should be taken to avoid
simultaneous contact between power ground wires and telephone cable or
guys since a small voltage may be present. This is recommended to avoid the
possibility of a shock that might cause a fall from the pole.
If an ungrounded street light fixture is less than 40 inches above or below
telephone attachments and is on a pole not carrying a telephone cable or a
bare vertical power ground wire, wear insulating gloves. Since it is not
possible to place a temporary bond to an effective ground, you should avoid
contact with the fixture.
Do not make contact with supply wires going to the fixture.
Loose Plant
In general, you should avoid unsecured objects, dangling wires, etc., which
would tend to move if probed. Breaking through corrosion is difficult in such
cases and there is a danger that the object might suddenly swing around and
hit you.
Temporary Bond
The temporary bond is used to temporarily ground a fixture, conduit, or bare
vertical ground wire which has been tested for and found to be free from a
voltage potential while working aloft. Should a fault develop, the temporary
bond will provide a direct path to ground for the foreign potential. The
