of the poles being hauled. The red flag or light should be visible in any direction. State highway
regulations should be observed when poles are transported on state highways.
e. Poles temporarily dispersed along streets and highways should be laid near the curb or
in parkways between the curb and sidewalk, where they will not interfere with traffic, driveways,
or walkways. When laid on an incline, poles should not be placed where they will interfere with
drainage. The foreman should decide whether or not danger signs by day and red lights at night
are required.
f. When moving a pole by hand, with a pole cart or with the truck derrick, warn those
nearby who might be struck accidentally. Station a worker with a red flag to warn or stop traffic
as necessary.
Pole Installation Requirements. Poles will normally be installed for new aerial
7.4
line construction by contract workers. However, facility-installed poles may be needed for short
line replacements of storm-damaged lines or because of pole decay. These poles may be installed
by either Navy or contract workers. Remember that poles and guys should be located relative to
local facility property line requirements.
7.4.1 Pole Holes. If new poles are to be set adjacent to existing poles to be dismantled,
new holes should be dug. Power tools are available for digging, such as power borers or augers
and should be used by qualified personnel. Rock cutting drills are available, as a safer alternative
to the use of explosives, where rock is encountered. Most facility-provided pole holes will
probably be dug by hand when power diggers are unavailable or cannot be used.
7.4.2 Digging Holes. Digging pole holes does not involve any great hazard, but does
contribute to a great number of minor injuries, such as eye injuries from flying dirt and rocks;
blisters on hands from the use of hand tools (blisters can be partially eliminated by using gloves);
and foot and leg injuries resulting from falling over tools left too close to the pole hole,
particularly shovels that have been left turned up.
7.4.3 Hole Covers. Hole covers should be at least 750 millimeters (30 inches) in
diameter. Covers may be made of 25 millimeters (1-inch) thick lumber with two cross braces not
smaller than 25 by 100 millimeters (1 inch by 4 inches) in cross section. Four or five shovels of
soil should be put on the cover after it is placed over the hole. Casings may be required in sand or
swampy soil to prevent the sides of a hole from caving in. Casing covers are required if pole
setting is not done immediately.
