boom sections shall be inspected daily to ensure the

ELECTROCUTION HAZARD
Thoroughly read, understand, and abide by all applicable
federal, state, and local regulations regarding operation of
equipment near electric power lines or equipment.
United States federal law prohibits the use of
equipment closer than 6 m (20 ft) to power
sources up to 350 kV and greater distances for
higher voltages unless the line’s voltage is
known [29CFR1910.180 and 29CFR1926.1400].
To avoid death or serious injury, National Crane
recommends that all parts of equipment, boom,
and load be kept at least 6 m (20 ft) away from
all electrical power lines and equipment less
than 350 kV.
NOTE: For detailed guidelines on operating near power
lines, refer to the current edition of OSHA
29CFR1926.1408 and ASME B30.5 American
National Standard.
If operation within 3 m (10 ft) of any power lines cannot be
avoided, the power utility must be notified and the power
lines must be de-energized and grounded before
performing any work.
Electrocution can occur even without direct contact with the
equipment.
Equipment operation is dangerous when close to an
energized electrical power source. Exercise extreme caution
and prudent judgement. Operate slowly and cautiously when
in the vicinity of power lines.
Before operating this equipment in the vicinity of electrical
power lines or equipment, notify the power utility company.
Obtain positive and absolute assurance that the power has
been turned off.
This equipment is not insulated. Always consider all parts of
the load and the equipment, including the wire rope, hoist
rope, pendant cables, and tag lines, as conductors. You, the
operator, are responsible for alerting all personnel of
dangers associated with electrical power lines and
equipment. Do not allow unnecessary personnel in the
vicinity of the equipment while operating. Permit no one to
lean against or touch the equipment. Permit no one,
including riggers and load handlers, to hold the load, load
lines, tag lines, or rigging gear.
If the load, wire rope, boom, or any portion of the equipment
contacts or comes too close to an electrical power source,
everyone in, on, and around the equipment can be seriously
injured or killed.
WARNING
Electrocution Hazard!
National Crane equipment is not equipped with all
features required to operate within OSHA
