Federal OSHA Regulations
  • 29CFR1926.453 Subpart L, Aerial Lifts
  • 29CFR1910.67 Subpart F
  • Vehicle-Mounted Elevating Rotating Work
    Platforms
  • 29CFR1910.333 Subpart S

3
ANSI Standards
  • ANSI/SIA A92.2-2001 Manual of
  • Responsibilities for Dealers, Owners, Users,
  • Operators, Lessors, and Lessees of Vehicle-
  • Mounted Elevating and Rotating Aerial Devices.
  • ANSI/SIA A92.3-1990, Manually Propelled
  • Elevating Aerial Platforms
  • ANSI/SIA A92.6-1999, Self-Propelled
  • Elevating Work Platforms
  • ANSI/SIA A92.7-1998, Airline Ground
  • Support Vehicle-Mounted Vertical Lift Devices
  • ANSI/SIA A92.8-1993 (reaffirmed 1998),
  • Vehicle-Mounted Bridge Inspection and
  • Maintenance Devices

Federal OSHA Exemptions
  • Remember This section does not apply to fire
    fighting equipment

5
Definitions
  • Aerial Device Any vehicle mounted or self
    propelled device, telescoping extensible or
    articulation, or both, which are designed to
    position personnel.
  • Articulation Boom An aerial device with two
    or more hinged boom sections.
  • Aerial Ladder An aerial device consisting of a
    single or multiple section extensible
    ladder.
  • Boom An elevating member the lower end of
    which is attached to a rotating or
    non- rotating base that permits elevation of
    the free or outer end.

6
Definitions - cont.
  • Elevating Work Platform A device designed to
    elevate a platform in a substantially
    vertical axis (vertical tower, scissor
    lift).
  • Extensible Boom Platform An aerial device with
    an extensible boom. Telescopic booms
    with personnel platforms
    attachments shall be considered to be
    extensible boom platforms
  • Vertical Tower An aerial device designed to
    elevate a platform in a
    substantially vertical axis.

Work Environment Considerations
  • Location of the work
  • Inside or outside
  • Enough room
  • Gas, propane, diesel, electric or manually
    powered
  • Operating Terrain
  • Hard or soft tires
  • Maximum height required
  • Weight capacity needed
  • Fall protection needed
  • Energized lines or equipment present

18
Manufactures Requirements
  • An operations manual is required
  • Manual must cover maintenance
  • An identification plate that includes
  • Make, model and I.D.
  • Rated capacity
  • Maximum travel height
  • Maximum operating pressure of
    hydraulic/pneumatic system
  • Rated line voltage
  • Cautions /or restrictions

19
Training
  • OSHA requires that all Operators be trained for
    the aerial device they are using (Qualified
    Operator). This training is to be documented,
    retained and available.

20
Training
21
General Requirements
  • Guardrails 42 inches high required on all
    sides. Where a guardrail is less than 42 inches
    high personal fall protection is required.
  • A midrail and toeboards are required on all
    sides.
  • No one can sit or stand on the guardrails.
  • Securing to an adjacent pole, structure or
    other equipment is prohibited.
  • Putting a scaffold, ladder, box, bucket,
    planks, etc. to increase the height of a platform
    is prohibited.
  • Aerial devices can not be leaned upon
    buildings, structures, or other equipment.

22
General Requirements - cont.
  • Articulating boom and extensible boom
    platforms, primarily designed as personnel
    carriers shall have both platform (upper) and
    lower controls.
  • Vehicles must be inspected prior to use and
    annually (ANSI Standard Requirement).

23
Elevated Platform Traveling Requirements
  • A worker can ride an aerial device in an
    elevated position when permitted by the
    manufacturer and the following conditions are met
  • Travel speed does not exceed three (3) feet per
    second
  • Units that have maximum travel height shall
    have an interlock to prohibit movement.
  • Surface is level with no hazards or
    accumulation of debris

24
Aerial Devices Around Energized Equipment or Line
  • Near energized lines/equipment aerial devices
    shall be grounded or barricaded and considered as
    energized equipment, or the aerial device shall
    be insulated for the voltage exposure.
  • Insulating booms of aerial devices used for
    work on energized high voltage conductors and
    equipment shall have a dielectric test performed
    every 12 months (ANSI regulation)
  • Equipment, materials, or tools shall not be
    passed between a pole or structure and an aerial
    device while a worker from the aerial device is
    in reaching distance of unprotected energized
    equipment/lines.
