rotating superstructure (whether permanently or temporarily mounted) poses a
reasonably foreseeable risk of:
(i) Striking
and injuring an employee; or
(ii)
Pinching/crushing an employee against another part of the crane or another
object.
(b) To prevent
employees from entering these hazard areas, you must:
(i) Train each employee assigned to work on
or near the crane (authorized personnel) in how to recognize struck-by and
pinch/crush hazard areas posed by the rotating superstructure.
(ii) Erect and maintain control lines,
warning lines, railings or similar barriers to mark the boundaries of the
hazard areas.
|
Exception:
|
When you can demonstrate that it is neither feasible to
erect such barriers on the ground nor on the crane, the hazard areas must be
clearly marked by a combination of warning signs (such as Danger-Swing/Crush
Zone) and high visibility markings on the crane that identify the hazard areas.
In addition, you must train each employee to understand what these markings
signify. |
(c)
Protecting employees in the hazard
area.
(i) Before an employee goes to a
location in the hazard area that is out of view of the operator, the employee
(or someone instructed by the employee) must ensure that the operator is
informed that he/she is going to that location.
(ii) Where the operator knows that an
employee went to a location covered by subsection (43)(c)(i) of this section,
the operator must not rotate the superstructure until the operator is informed
in accordance with a prearranged system of communication that the employee is
in a safe position.
(d)
Where any part of a crane/derrick is within the working radius of another
crane/derrick, the controlling entity must institute a system to coordinate
operations. If there is no controlling entity, the employer (if there is only
one employer operating the multiple pieces of equipment), or employers, must
institute such a system.
(43)
Keeping clear of the load.
(a) Where available, hoisting routes that
minimize the exposure of employees to hoisted loads must be used to the extent
consistent with public safety.

rated capacity of the crane/derrick by at least one of the following methods:
(a) The weight of the load must be determined
from a reliable source recognized by the industry (such as the load's
manufacturer), or by a reliable calculation method recognized by the industry
(such as calculating a steel beam from measured dimensions and a known per foot
weight), or by other equally reliable means. In addition, when requested by the
operator, this information must be provided to the operator prior to the lift;
or
(b) The operator must begin
hoisting the load to determine, using a load weighing device, load moment
indicator, rated capacity indicator, or rated capacity limiter. If the load
exceeds 75% of the maximum rated capacity at the longest radius that will be
used during the lift operation, the operator must not proceed with the lift
until it is verified that the weight of the load is in accordance with (a) of
this subsection.
(63)
Tag lines or restraint lines must be used when rotation or swinging of the load
is hazardous or if the load needs guidance. Tag lines are not required when all
of the following criteria are met:
* The suspended load can be expected to remain still when in
a static (nonmoving) condition or does not swing or rotate in a hazardous
manner;
* The movement of the crane or boom cannot be expected to
cause the load to swing or rotate in an uncontrolled manner that may create a
hazard;
* The operator is in control of the movement of the load and
a hazardous condition is not created.
(64) All brakes must be adjusted in
accordance with manufacturer procedures to prevent unintended
movement.
(65) Safety devices
and/or operational aids must not be used as a substitute for the exercise of
professional judgment by the operator.
(66)
Storm warning. When a local
storm warning has been issued, the competent person must determine whether it
is necessary to implement manufacturer recommendations for securing the
crane/derrick.
(67) Whenever there
is a concern as to safety, the operator has the authority to stop and refuse to
handle loads until a qualified person has determined that safety has been
assured.
(68)
Tag-out.
(a) Tagging out of service. Where you have
taken the crane/derrick out of service, a tag must be placed in the cab or at
the operator station stating that the equipment is out of service and is not to
be used. Where you have taken a function(s) out of service, a tag must be
placed in a conspicuous position stating that the function is out of service
and is not to be used.
(b)
Response to do not operate/tag-out signs.
(i) If there is a warning (tag-out or
maintenance/do not operate) sign on the crane/derrick or starting control, the
operator must not activate the switch or start the crane/derrick until the sign
has been removed by a person authorized to remove it, or until the operator has
verified that:
(A) No one is servicing,
working on or otherwise in a dangerous position around the machine.
(B) The crane/derrick has been repaired and
is working properly.
(ii) If there is a warning (tag-out or
maintenance/do not operate) sign on any other switch or control, the operator
must not activate that switch or control until the sign has been removed by a
person authorized to remove it, or until the operator has verified that the
requirements in (b)(i)(A) and (B) of this subsection have been met.

For additional lockout/tagout procedures for electrical
circuits, see WAC
296-155-429.

(69) If crane/derrick adjustments or repairs
are necessary:
(a) The operator must, in
writing, promptly inform the person designated by you to receive such
information and, where there are successive shifts, to the next operator;
and
(b) You must notify all
affected employees, at the beginning of each shift, of the necessary
adjustments or repairs and all alternative measures.
(70) All cranes and derricks mounted on
barges or other floating structures must meet the requirements as outlined in
ASME B30.8-2004 for construction, installation, inspection, maintenance and
operation.
(71)
Swinging
locomotive cranes. A locomotive crane must not be swung into a position
where railway cars on an adjacent track could strike it, until it is determined
that cars are not being moved on the adjacent track and that proper flag
protection has been established.
(72)
Remote control
cranes/derricks. Before an operator leaves the crane/derrick to operate
remotely, the operator must ensure that the crane/derrick will be used in
accordance with the manufacturer's recommendations. Provisions must be made to
prevent simultaneous activation of controls when more than one control station
(remote control) is provided.
(73)
Remote-operated cranes/derricks must function so that if the control signal for
any crane/derrick motion becomes ineffective, the crane/derrick motion must
stop.
(74) Remote-operated
cranes/derricks must be equipped with an "emergency stop" system, located at
the operator's remote station to provide the means to remove power from the
crane in the event of a malfunction.
(75) A preventative maintenance program must
be established based on the recommendation of the crane/derrick manufacturer.
If manufacturer's recommendations are not available, then those of a qualified
person must be followed. Dated records must be kept available.
(76)
Working with a diver. You
must meet the following additional requirements when working with a diver in
the water:
(a) If a crane/derrick is used to
get a diver into and out of the water, it must not be used for any other
purpose until the diver is removed from the water. When used for more than one
diver, it must not be used for any other purpose until all divers are all out
of the water.
(b) The operator
must remain at the controls of the crane/derrick at all times.
(c) In addition to the requirements in WAC
296-155-53406, Signals,
either:
(i) A clear line of sight must be
maintained between the operator and dive tender; or
(ii) The signals between the operator and
dive tender must be transmitted electronically.
