4. 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.

17. 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. Manufacture’s 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.
