c. Ducts will always be fished in the direction that presents the least hazard. A worker
will be stationed at each end when required.
d. Avoid parking tool carts and reels on inclined streets. Where this cannot be avoided,
equipment should be placed at a slight angle to the curb so that the curb serves as a chock.

Existing Obstruction Protection. When obstructions such as existing utilities
are encountered in digging, the supervisor should be notified immediately, so that damaging or
hazardous contact with energized cables may be avoided. Excavation practices and procedures
for damage prevention to existing utilities are covered in 8.4.
8.3.1 Locating Buried Facilities. Use area utility maps to locate existing utilities as
accurately as possible.
Direct-Burial Electrical Cable Work
Extreme care will be used in excavating near or exposing direct-burial electric
underground cables. Before excavating the location of the cables should be
determined. If the depth of all direct-burial cables is definitely known, power
digging equipment may be used for excavating all but the last 300 millimeters (12
inches) of cover over the cables. The remaining cover will be removed by use of
shovels with wooden handles or similar hand-digging tools. Where the depth of
direct-burial cables is not established, power digging equipment should not be
used, except to break and remove the surface pavement.
