contact with a power line
Jump - CORRECT ANSWER - If it is necessary to leave the crane cab before power lines are
de-energized after contact, how does the operator exit the cab

is allowed by the
Backward collapse - CORRECT ANSWER - Ensure the boom low enough when traveling
with a load to avoid the possibility of this
Toward the load - CORRECT ANSWER - Always travel in this direction when traveling with
a load
