1910.67(b)(1)
Unless otherwise provided in this section, aerial devices
(aerial lifts) acquired on or after July 1, 1975, shall be designed and
constructed in conformance with the applicable requirements of the
American National Standard for "Vehicle Mounted Elevating and Rotating
Work Platforms," ANSI A92.2 - 1969, including appendix, which is
incorporated by reference as specified in 1910.6. Aerial lifts acquired
for use before July 1, 1975 which do not meet the requirements of ANSI
A92.2 - 1969, may not be used after July 1, 1976, unless they shall have
been modified so as to conform with the applicable design and construction
requirements of ANSI A92.2 - 1969. Aerial devices include the following
types of vehicle-mounted aerial devices used to elevate personnel to
jobsites above ground:
1910.67(b)(1)(i)
Extensible boom platforms,
..1910.67(b)(1)(ii)
1910.67(b)(1)(ii)
aerial ladders,
1910.67(b)(1)(iii)
articulating boom
platforms,
1910.67(b)(1)(iv)
vertical towers, and
1910.67(b)(1)(v)
a combination of any of the above. Aerial equipment may be
made of metal, wood, fiberglass reinforced plastic (FRP), or other
material; may be powered or manually operated; and are deemed to be aerial
lifts whether or not they are capable of rotating about a substantially
vertical axis.
1910.67(b)(2)
Aerial lifts may be "field modified" for uses other than
those intended by the manufacturer, provided the modification has been
certified in writing by the manufacturer or by any other equivalent
entity, such as a nationally recognized testing laboratory, to be in
conformity with all applicable provisions of ANSI A92.2 - 1969 and this
section, and to be at least as safe as the equipment was before
modification.
1910.67(b)(3)
The requirements of this section do not apply to
firefighting equipment or to the vehicles upon which aerial devices are
mounted, except with respect to the requirement that a vehicle be a stable
support for the aerial device.
1910.67(b)(4)
For operations near overhead electric power lines, see
1910.333(c)(3).
..1910.67(c)
1910.67(c)
"Specific requirements" -
1910.67(c)(1)
"Ladder trucks and tower trucks." Before the truck is
moved for highway travel, aerial ladders shall be secured in the lower
traveling position by the locking device above the truck cab, and the
manually operated device at the base of the ladder, or by other equally
effective means (e.g., cradles which prevent rotation of the ladder in
combination with positive acting linear actuators).
1910.67(c)(2)
"Extensible and articulating boom platforms."
1910.67(c)(2)(i)
Lift controls shall be tested each day prior to use to
determine that such controls are in safe working condition.
1910.67(c)(2)(ii)
Only trained persons shall operate an aerial lift.
1910.67(c)(2)(iii)
Belting off to an adjacent pole, structure, or equipment
while working from an aerial lift shall not be permitted.
1910.67(c)(2)(iv)
Employees shall always stand firmly on the floor of the
basket, and shall not sit or climb on the edge of the basket or use
planks, ladders, or other devices for a work position.
1910.67(c)(2)(v)
A body belt shall be worn and a lanyard attached to the
boom or basket when working from an aerial lift.
1910.67(c)(2)(vi)
Boom and basket load limits specified by the manufacturer
shall not be exceeded.
1910.67(c)(2)(vii)
The brakes shall be set and outriggers, when used, shall
be positioned on pads or a solid surface. Wheel chocks shall be installed
before using an aerial lift on an incline.
..1910.67(c)(2)(viii)
1910.67(c)(2)(viii)
An aerial lift truck may not be moved when the boom is
elevated in a working position with men in the basket, except for
equipment which is specifically designed for this type of operation in
accordance with the provisions of paragraphs (b)(1) and (b)(2) of this
section.
1910.67(c)(2)(ix)
Articulating boom and extensible boom platforms, primarily
designed as personnel carriers, shall have both platform (upper) and lower
controls. Upper controls shall be in or beside the platform within easy
reach of the operator. Lower controls shall provide for overriding the
upper controls. Controls shall be plainly marked as to their function.
Lower level controls shall not be operated unless permission has been
obtained from the employee in the lift, except in case of emergency.
1910.67(c)(2)(x)
Climbers shall not be worn while performing work from an
aerial lift.
1910.67(c)(2)(xi)
The insulated portion of an aerial lift shall not be
altered in any manner that might reduce its insulating value.
1910.67(c)(2)(xii)
Before moving an aerial lift for travel, the boom(s) shall
be inspected to see that it is properly cradled and outriggers are in
stowed position, except as provided in paragraph (c)(2)(viii) of this
section.
..1910.67(c)(3)
1910.67(c)(3)
"Electrical tests." Electrical tests shall be made in
conformance with the requirements of ANSI A92.2 - 1969, Section 5.
However, equivalent DC voltage tests may be used in lieu of the AC voltage
test specified in A92.2 - 1969. DC voltage tests which are approved by the
equipment manufacturer or equivalent entity shall be considered an
equivalent test for the purpose of this paragraph (c)(3).
1910.67(c)(4)
"Bursting safety factor." All critical hydraulic and
pneumatic components shall comply with the provisions of the American
National Standards Institute standard, ANSI A92.2 - 1969, Section 4.9
Bursting Safety Factor. Critical components are those in which a failure
would result in a free fall or free rotation of the boom. All noncritical
components shall have a bursting safety factor of at least two to one.
1910.67(c)(5)
"Welding standards." All welding shall conform to the
following Automotive Welding Society (AWS) Standards which are
incorporated by reference as specified in 1910.6, as applicable:
