3
Overhead power lines must be considered to be in this condition until electrical
authorities indicate otherwise - ANSWER: Energized
No part of the crane or load must ever enter this area around an energized power
line - ANSWER: Prohibited zone
The prohibited zone must be enlarged as this increases - ANSWER: kV

kV is unknown - ANSWER: 20 foot
What minimum distance is required if the voltage is over 350 kV and unknown -
ANSWER: 50 foot
This person must be appointed any time the crane is working within a boom's length
of the prohibited zone - ANSWER: Qualified signal person
The use of these should be avoided when lifting near power lines, however if
necessary should be non-conductive type - ANSWER: Tag lines
Avoid operating cranes or handling materials in this area of power lines - ANSWER:
Above power lines
What does an operator do if the crane comes in contact with a power line -
ANSWER: Remain in the cab
If it is necessary to leave the crane cab before power lines are de-energized after
contact, how does the operator exit the cab - ANSWER: Jump
A crane can also become electrically charged when working close to these (radio,
microwave, cell) - ANSWER: transmission towers
, Before traveling on site with a load, be sure that this is allowed by the - ANSWER:
Manufacturer
Ensure the boom low enough when traveling with a load to avoid the possibility of
this - ANSWER: Backward collapse
Always travel in this direction when traveling with a load - ANSWER: Toward the
load
Most manufacturers do not permit travel with a load when the boom is in these
settings - ANSWER: Boom extension, jib, or pinned section
To prevent a lattice boom crane from tipping forward, the boom should be in this
position before traveling down an incline - ANSWER: Raised
To prevent a lattice boom crane from tipping backwards, the boom should be in this
position when traveling up an incline - ANSWER: Lowered
Responsible for seeing that the ground conditions are adequate to support the
equipment. - ANSWER: Controlling entity
Responsible for informing the user and the operator of the equipment of the
location of hazards beneath the equipment set-up area (such as voids, tanks,
utilities) - ANSWER: Controlling entity
Responsible for establishing a system to coordinate the operations of two cranes
that operate within each other's working radius - ANSWER: Controlling entity
hoist rope & reeving, op aids & safety devices, cab windows/equipment, hooks &
latches, fluid levels (crankcase oil, coolant, hydraulic oil, etc.), elec equipment,
leveling device, control & drive mechanisms, fire extinguisher, air/hydraulic system -
