PART 1910_OCCUPATIONAL SAFETY AND HEALTH STANDARDS--Table of Contents
Subpart F_Powered Platforms, Manlifts, and Vehicle-Mounted Work
Platforms
Sec. 1910.67 Vehicle-mounted elevating and rotating work platforms.
(a) Definitions applicable to this section--(1) Aerial device. Any
vehicle--mounted device, telescoping or articulating, or both, which is
used to position personnel.
(2) Aerial ladder. An aerial device consisting of a single- or
multiple-section extensible ladder.
(3) Articulating boom platform. An aerial device with two or more
hinged boom sections.
(4) Extensible boom platform. An aerial device (except ladders) with
a telescopic or extensible boom. Telescopic derricks with personnel
platform attachments shall be considered to be extensible boom platforms
when used with a personnel platform.
(5) Insulated aerial device. An aerial device designed for work on
energized lines and apparatus.
(6) Mobile unit. A combination of an aerial device, its vehicle, and
related equipment.
(7) Platform. Any personnel-carrying device (basket or bucket) which
is a component of an aerial device.
(8) Vehicle. Any carrier that is not manually propelled.
(9) Vertical tower. An aerial device designed to elevate a platform
in a substantially vertical axis.
(b) General requirements. (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
Sec. 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: (i)
Extensible boom platforms, (ii) aerial ladders, (iii) articulating boom
platforms, (iv) vertical towers, and (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.
(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.
(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.
(4) For operations near overhead electric lines, see Sec.
1910.333(c)(3).
(c) Specific requirements--(1) Ladder trucks and tower trucks.
Before the
[[Page 187]]
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).
(2) Extensible and articulating boom platforms. (i) Lift controls
shall be tested each day prior to use to determine that such controls
are in safe working condition.
(ii) Only trained persons shall operate an aerial lift.
(iii) Belting off to an adjacent pole, structure, or equipment while
working from an aerial lift shall not be permitted.
(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.
(v) A body belt shall be worn and a lanyard attached to the boom or
basket when working from an aerial lift.
(vi) Boom and basket load limits specified by the manufacturer shall
not be exceeded.
(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.
(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.
(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.
(x) Climbers shall not be worn while performing work from an aerial
lift.
(xi) The insulated portion of an aerial lift shall not be altered in
any manner that might reduce its insulating value.
(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.
(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).
(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.
(5) Welding standards. All welding shall conform to the following
Automotive Welding Society (AWS) Standards, which are incorporated by
reference as specified in Sec. 1910.6, as applicable:
(i) Standard Qualification Procedure, AWS B3.0--41.
(ii) Recommended Practices for Automotive Welding Design, AWS D8.4-
61.
(iii) Standard Qualification of Welding Procedures and Welders for
Piping and Tubing, AWS D10.9-69.
(iv) Specifications for Welding Highway and Railway Bridges, AWS
D2.0-69.
