SAFETY INFORMATION
ELECTROCUTION HAZARD
Thoroughly read, understand, and abide by all applicable
federal, state, and local regulations regarding operation of
cranes near electric power lines or equipment.
United States federal law prohibits the use of
cranes 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 crane, 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
crane.
Crane 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 crane 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 crane is
not insulated
. Always consider all parts of the
load and the crane, including the wire rope, hoist cable,
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 crane while operating. Permit no one to lean
against or touch the crane. 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 crane
contacts or comes too close to an electrical power source,
everyone in, on, and around the crane can be seriously
injured or killed.
Most overhead power lines
are not
insulated. Treat all
overhead power lines as being energized unless you have
reliable information to the contrary from the utility company
or owner.
WARNING
Electrocution Hazard!
National cranes are not equipped with all features
required to operate within OSHA 29CFR1926.1408, Table
A clearances when the power lines are energized.
