7.10.8.2 Removal of Guys. Before guys can be removed, the condition of the pole should
be determined. If the pole is weak, it should be securely braced before any changes in pole strains
are made.
a. Where the removal of guys from a pole will change the strain and present a dangerous
condition, the pole should be braced temporarily to make such a changed condition safe.
b. Where it is not possible to install side guys, poles may need to be braced to be
self-supporting. The pole bracing should be installed so that it will not interfere with climbing or
with street or highway traffic. Pole braced guys should not be used on poles which will be
climbed.
7.10.9 Insulators. Pick up insulators by their tops to avoid cutting gloves or hands on
insulator petticoats. Do not screw down insulators too tightly because their tops may break off,
cutting gloves or hands.
Streetlighting. Streetlighting circuits can be either low-voltage multiple circuits
7.11
or medium-voltage series circuits. It is important that the type of circuit be identified because of
the voltage level differences. There should be no reason that streetlighting circuits cannot be
de-energized for daytime work.
7.11.1 Streetlighting Precautions. Streetlighting line wires and streetlighting fixtures
and wires, not under construction or grounded, should be considered energized and should always
be worked with rubber protective equipment, unless de-energized and grounded. The voltage of
streetlighting circuits should be treated as that of the highest voltage occupying one or more poles
on which the streetlighting circuit is run. This is necessary because streetlighting wires sometimes
become crossed with live voltage wires during a fire or during the day when not in use.
7.11.2 Multiple Streetlighting Circuits. Multiple streetlighting circuits should be
considered to be at the same voltage as the circuits to which they are connected, unless the circuit
is on the same structure with a higher voltage wire, in which case it should be considered to be at
the higher voltage level.
7.11.3 Series Streetlighting Circuits. Before a series streetlighting circuit is opened
and work is performed, the following procedures will be followed:
a. A circuit should be disconnected from the source of supply by opening disconnecting
switches or other absolute voltage cutouts, and lockout/tagout/tryouts attached to such
disconnects or cutouts. Do not depend on time switches or other automatic devices.
b. A circuit should be properly jumpered to avoid an open-circuit condition.
