SOL Complainant v Jesco Inc Docket 10-0265 Contest: 29 C. F. R. § 1910.67(b)(2), for using a “field modified” aerial lift without first obtaining written certification from the manufacturer of the aerial lift. The Secretary proposed a penalty of $ 4,500.00 for the violation. Finding: The court finds the Secretary established a serious violation of 29 C. F. R. § 1910.67(b)(2). Item 1 of Citation No. 1 is affirmed, and a penalty of $ 2,500.00 is assessed. • • • employees performed an unapproved field modification of a rented JLG Aerial Boom Lift by using clamps to attach 325-pound, 31-foot long beams to the guardrails of the Lift’s platform and using the Lift to lower and lift the beams to the ceiling, 31-feet above. The Operation and Safety Manual for the Lift instructs users to “not carry materials directly on platform railing” and further states that “[s]upplies or tools which extend outside the platform are prohibited unless approved by JLG.” (b) On or about August 29, 2009, at Mueller Copper Fittings, employees performed an unapproved field modification of a rented JLG Aerial Boom Lift by placing 325-pound, 31foot long beams on the guardrails of the Lift’s platform and using the Lift to lower and lift the beams to the ceiling, 31.5-feet above. The Operation and Safety Manual for the Lift instructs users to “not carry materials directly on platform railing” and further states that “[s]upplies or tools which extend outside the platform are prohibited unless approved by JLG.” Excavation Standard – EE had clear view - Deleted • 1926.651(f) Warning system for mobile equipment. When mobile equipment is operated adjacent to an excavation, or when such equipment is required to approach the edge of an excavation, and the operator does not have a clear and direct view of the edge of the excavation, a warning system shall be utilized such as barricades, hand or mechanical signals, or stop logs. If possible, the grade should be away from the excavation. CFR 1926.453(a)(1) • Unless otherwise provided in this section, aerial lifts acquired for use on or after January 22, 1973 shall be designed and constructed in conformance with the applicable requirements of the American National Standards for "Vehicle Mounted Elevating and Rotating Work Platforms," ANSI A92.21969, including appendix. Aerial lifts acquired before January 22, 1973 which do not meet the requirements of ANSI A92.2-1969, may not be used after January 1, 1976, unless they shall have been modified so as to conform with the applicable design and construction requirements of ANSI A92.2-1969. Aerial lifts include the following types of vehicle-mounted aerial devices used to elevate personnel to job-sites above ground: Question (1): Does §1926.453(b)(2)(i) through (xii) apply to self propelled boom-supported elevating work platforms, such as those dealt with in ANSI A92.5 (1992), or does it only cover elevating and rotating work platforms mounted on vehicles? Answer: The "aerial lifts" covered by this section are those that are considered aerial lifts in ANSI A92.2-1969 (see §1926.453(a)). The ANSI A92.2-1969 standard, under 1.1.1 "Equipment Covered," states that it covers: the following types of vehicle-mounted aerial devices used to elevate personnel to job sites above ground: (1) Extensible boom platforms; (2) aerial ladders; (3) articulating boom platforms; (4) vertical towers; (5) a combination of any of the above. These devices are made of metal, wood, fiberglass reinforced plastic (FRP), or other material and are powered or manually operated; whether or not they are capable or rotating about a substantially vertical axis. Under section 2 of the ANSI standard ("Definitions"), "vehicle" is defined as "any carrier that is not manually propelled." So, to be within the coverage of the ANSI standard, and thus the requirements of §1926.453, the "aerial device" can be powered or manually operated, but it must be vehicle-mounted -- and the vehicle must be a "carrier that is not manually propelled." Because the ANSI definition of "vehicle" is so broad, "vehicle" is not limited to over-theroad trucks. In answer to your question, boom-supported elevating work platforms identified in ANSI A92.5 (1992) are covered by §§1926.453(b)(2)(i) through (xii) if they are mounted on powered carriers. ANSI A 92.5 ANSI/SIA A92.5-2006 American National Standard Boom-Supported Elevating Work Platforms 1.1.1 Equipment Covered. This standard applies to self-propelled integral chassis aerial platforms having a platform that can be positioned completely beyond the base and are used to position personnel, along with their necessary tools and materials, at work locations. Aerial platforms are power operated with primary functions, including drive, controlled from the platform. Such aerial platforms are intended to be occupied when driven. ….(3) Responsibilities for dealers, owners, users, operators, lessors, lessees and brokers. All provisions detailed for dealers, owners, users, operators, lessors, lessees and brokers apply to both new and existing units delivered by sale, lease, rental or any form of beneficial use on or after the effective date. ANSI/SIA A92.6-2006 ANSI/SIA A92.6-2006 Self-Propelled Elevating Work Platforms • Applies to self-propelled, integral chassis aerial platforms having a platform that cannot be positioned completely beyond the base and are used to position personnel, along with their necessary tools and materials, at work locations. Platforms are adjustable by manual or powered means and shall not be occupied when moved horizontally.

Publication Date: 02/24/2010 Publication Type: Notice Fed Register #: 75:8406-8407 Standard Number: 1926.453 •Title: Aerial Lifts; Extension of the Office of Management and Budget's (OMB) Approval of an Information Collection (Paperwork) Requirement. How do I know what to inspect? Question: Is it permissible to allow workers to stand on boom lift1 guardrails or scissor lift guardrails in order to perform work if they use a personal fall arrest system? Aerial lifts The answer is no for aerial lifts. Section 1926.453(b)(2)(iv) states that "employees shall always stand firmly on the floor of the basket, and shall not sit or climb on the edge of the basket or use planks, ladders, or other devices for a work position." Scissor lifts The requirements of 29 CFR Part 1926 Subpart L (Scaffolds) applies to scissor lifts. There is no single provision in the scaffold standard that states that this practice is prohibited. However, as a practical matter, it is unlikely that all the requirements of the scaffold standard could be met while engaging in this practice. Use of personal fall protection would not be a substitute for compliance with these scaffold requirements - these plus the fall protection requirements2 must be met. Note that §1926.502(d)(23) prohibits personal fall arrest systems to be attached to guardrails systems. Therefore, the system would have to be anchored to either the scissor lift or an adjacent structure.3 Question 1: Do the OSHA standards permit employers to use aerial lifts to transport workers to and from elevated work stations where the basket is either set down on an elevated surface or placed at the edge of a structure? Answer: OSHA standards do not prohibit employees from exiting or entering an aerial lift basket that rests on or adjacent to an elevated surface. Section 1926.453(b)(2)(v) requires that employees working from aerial lifts be tied-off. On the other hand, when employees move from the basket to the elevated surface, the requirements in 29 CFR Part 1926 Subpart M apply. In particular, §1926.501(b)(1) requires fall protection at 6 feet above a lower level. A worker may enter or exit an aerial lift (at heights above 6 feet) provided that fall protection such as guardrails or a fall arrest system is used while the worker moves between the lift and the working surface. A fall arrest system and its components must meet the criteria in §1926.502(d). During entry to and egress from the lift, a worker may tie-off to the lift (if the lift is designed to withstand the vertical and lateral loads imposed by the employee's movement itself or by an arrested fall) or to an appropriate nearby structure.
