1 Aerial Lifts & Other Elevating Platforms Chuck Northam

2 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

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

5 Definitions n Aerial Device:Any vehicle mounted or self propelled device, telescoping extensible or articulation, or both, which are designed to position personnel. n Articulation Boom: An aerial device with two or more hinged boom sections. n Aerial Ladder:An aerial device consisting of a single or multiple section extensible ladder. n 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 n Location of the work: – Inside or outside – Enough room – Gas, propane, diesel, electric or manually powered n Operating Terrain – Hard or soft tires n Maximum height required n Weight capacity needed n Fall protection needed n Energized lines or equipment present

18 Manufactures Requirements n An operations manual is required – Manual must cover maintenance n 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 n 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 n Guardrails 42 inches high required on all sides. Where a guardrail is less than 42 inches high personal fall protection is required. n A midrail and toeboards are required on all sides. n No one can sit or stand on the guardrails. n Securing to an adjacent pole, structure or other equipment is prohibited. n Putting a scaffold, ladder, box, bucket, planks, etc. to increase the height of a platform is prohibited. n Aerial devices can not be leaned upon buildings, structures, or other equipment.

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

23 Elevated Platform Traveling Requirements n 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 n 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. n 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) n 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.

25 CFR 1910.333Table S- 5 Approach Distances for Qualified Employees -- Alternating Current -------------------------------+------------------------------- Voltage range Minimum approach distance -------------------------------+------------------------------- | 300V and less................. Avoid contact. Over 300V, not over 750V. 1 ft. 0 in. (30.5 cm). Over 750V, not over 2kV. 1 ft. 6 in. (46 cm). Over 2kV, not over 15kV. 2 ft. 0 in (61 cm). Over 15kV, not over 37kV. 3 ft. 0 in. (91 cm). Over 37kV, not over 87.5kV. 3 ft. 6 in. (107 cm). Over 87.5kV, not over 121kV. 4 ft. 0 in. (122 cm). Over 121kV, not over 140kV. 4 ft. 6 in. (137 cm). -------------------------------------------------------------
