Federal OSHA Exemptions

Remember: This section does not apply to fire fighting equipment

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.

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

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

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

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.

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).

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

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.

Genie Lift

Compliant??

Retractable handrails results in personal fall protection needed...

Hard tire scissor lift...

Aerial lift with power platform extension

Remove material& debris from lift platform

Damaged equipment is to be repaired.

Why is a compressed gas cylinder and “hot” work dangerous on an aerial lift?

Rough-Terrain Boom lift.

Another Type of Boom Lift

What’s missing?

Elevator OK??

Articulating Boom lift.

Instructions & warnings on a boom lift

Not Even Close….

Only use equipment for it’s intended design
