TM 5-3810-302-10
Position the crane far enough away from power sources to ensure that
no part of the crane or load can reach to within an unsafe zone. This
includes the crane boom (fully extended to maximum height, radius,
and length) and all attachments (rigging, tag lines, etc.).
- Erect a suitable barricade to physically restrain the crane and all
attachments (including the load) from entering into an unsafe distance
from the power source.
- Obtain positive and absolute assurance that power has been turned
OFF.
IMPORTANT - Always consider the wire rope, hoist cable, pendant cables,
tag lines, etc. as conductors.
EXERCISE EXTREME CAUTION AND PRUDENT JUDGEMENT WHEN-
EVER ELECTROCUTION HAZARDS EXIST - OPERATE SLOWLY AND
CAUTIOUSLY.
Federal law prohibits use of cranes closer than 10 feet (3.048 m) to power
sources - to be safe, double that (i.e. 20 ft. [6.096 m] ).
Comply with all federal, state, and local laws and regulations.
It is not necessary to touch a power line or power source to become electro-
cuted. Electricity, depending on magnitude, can jump or become induced
into a crane. "Low" voltages can also be dangerous.
Be alert.
Keep all parts of the crane (ropes, lines, hook block, and Ioad) at least 20 feet
(6.096 m) from the line.
Slow down crane operations.
