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.

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

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.

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.
