(d) Crew instructions.
(1) Before commencing assembly/disassembly
operations, the A/D director shall ensure that the crew members understand all
of the following:
(A) Their tasks.
(B) The hazards associated with their
tasks.
(C) The hazardous
positions/locations that they need to avoid.
(2) During assembly/disassembly operations,
before a crew member takes on a different task, or when adding new personnel
during the operations, the requirements in subsections (d)(1)(A) through
(d)(1)(C) of this section shall be met.
(e) Protecting assembly/disassembly crew
members out of operator view.
(1) Before a
crew member goes to a location that is out of view of the operator and is
either in, on, or under the equipment, or near the equipment (or load) where
the crew member could be injured by movement of the equipment (or load), the
crew member shall inform the operator that they are going to that
location.
(2) Where the operator
knows that a crew member went to a location covered by subsection (e)(1), the
operator shall not move any part of the equipment (or load) until the operator
is informed in accordance with a prearranged system of communication that the
crew member is in a safe position.
(f) Working under the boom, jib or other
components.
(1) When pins (or similar devices)
are being removed, employees shall not be under the boom, jib, or other
components.
(g) Capacity
limits. During all phases of assembly/disassembly, rated capacity limits for
loads imposed on the equipment, equipment components (including rigging),
lifting lugs and equipment accessories, shall not be exceeded for the equipment
being assembled/disassembled.
(h)
Addressing specific hazards. The A/D director supervising the
assembly/disassembly operation shall address the hazards associated with the
operation, which include:
(1) Site and ground
bearing conditions. Site and ground conditions shall be adequate for safe
assembly/disassembly operations and to support the equipment during
assembly/disassembly (see Section
4991.1 for ground condition
requirements).
(2) Blocking
material. The size, amount, condition and method of stacking the blocking shall
be sufficient to sustain the loads and maintain stability.
(3) Proper location of blocking. When used to
support lattice booms or components, blocking shall be appropriately placed to:
(A) Protect the structural integrity of the
equipment, and
(B) Prevent
dangerous movement and collapse.
(4) Verifying assist crane loads. When using
an assist crane, the loads that will be imposed on the assist crane at each
phase of assembly/disassembly shall be verified in accordance with Section
4999(b) before
assembly/disassembly begins.
(5)
Boom and jib pick points. The point(s) of attachment of rigging to a boom (or
boom sections or jib or jib sections) shall be suitable for preventing
structural damage and facilitating safe handling of these components.
(6) Center of gravity.
(A) The center of gravity of the load shall
be identified if that is necessary for the method used for maintaining
stability.
(B) Where there is
insufficient information to accurately identify the center of gravity, measures
designed to prevent unintended dangerous movement resulting from an inaccurate
identification of the center of gravity shall be used.
(7) Stability upon pin removal. The boom
sections, boom suspension systems (such as gantry A-frames and jib struts), and
components shall be rigged or supported to maintain stability upon the removal
of the pins.
(8) Snagging.
Suspension ropes and pendants shall not be allowed to catch on the boom or jib
connection pins or cotter pins (including keepers and locking pins).
(9) Struck by counterweights. The potential
for unintended movement from inadequately supported counterweights and from
hoisting counterweights.
(10) Boom
hoist brake failure. Each time reliance is to be placed on the boom hoist brake
to prevent boom movement during assembly/disassembly, the brake shall be tested
prior to such reliance to determine if it is sufficient to prevent boom
movement. If it is not sufficient, a boom hoist pawl, other locking
device/back-up braking device, or another method of preventing dangerous
movement of the boom (such as blocking or using an assist crane) from a boom
hoist brake failure shall be used.
(11) Loss of backward stability. Backward
stability before swinging the upperworks, travel, and when attaching or
removing equipment components.
(12)
Wind speed and weather. The effect of wind speed and weather on the
equipment.
(i)
Cantilevered boom sections. Manufacturer limitations on the maximum amount of
boom supported only by cantilevering shall not be exceeded. Where these are
unavailable, a certified agent familiar with the type of equipment involved
shall determine in writing this limitation, which shall not be
exceeded.
(j) Weight of components.
The weight of each of the components shall be readily available.
(k) Components and configuration.
(1) The selection of components, and
configuration of the equipment, that affect the capacity or safe operation of
the equipment shall be in accordance with:
(A)
Manufacturer instructions, prohibitions, limitations, and specifications. Where
these are unavailable, a certified agent familiar with the type of equipment
involved shall approve, in writing, the selection and configuration of
components; or
(B) Approved
modifications that meet the requirements of Section
4884.1 (Equipment
Modifications).
(2)

inspected to ensure compliance with subsection (m)(1) (see Section
5031.1 for post-assembly inspection
requirements).
(l)
Shipping pins. Reusable shipping pins, straps, links, and similar equipment
shall be removed. Once they are removed they shall either be stowed or
otherwise stored so that they do not present a falling object hazard.
(m) Pile driving. Equipment used for pile
driving shall not have a jib attached during pile driving operations.
(n) Outriggers and stabilizers. When the load
to be handled and the operating radius require the use of outriggers or
stabilizers, or at any time when outriggers or stabilizers are used, all of the
following requirements shall be met (except as otherwise indicated):
(1) The outriggers or stabilizers shall be
either fully extended or, if manufacturer procedures permit, deployed as
specified in the load chart.
(2)
The outriggers shall be set to remove the equipment weight from the wheels,
except for locomotive cranes [see subsection (q)(6) for use of outriggers on
locomotive cranes]. This provision does not apply to stabilizers.
(3) When outrigger floats are used, they
shall be attached to the outriggers. When stabilizer floats are used, they
shall be attached to the stabilizers.
(4) Each outrigger or stabilizer shall be
visible to the operator or to a signal person during extension and
