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

Retractable handrails results in personal fall protection needed...
Why is a compressed gas cylinder and “hot” work dangerous on an aerial lift?
