Abstract

Three new industry standards, American National Standard/Scaffold & Access Industry Association, Inc. (ANSI/SAIA) A92.20, A92.22 and A92.24, were introduced in December 2018 to address the safe design, use and training associated with mobile elevating work platforms (MEWPs). MEWPs are defined in the new Standards as “machine/device intended for moving persons, tools and material to working positions, consisting of at least a work platform with controls, an extending structure and a chassis.”2 This definition encompasses certain types and sizes of MEWPs such as scissor lifts, articulating boom lifts, telescopic boom lifts and straight mast boom lifts. Replacing product-specific industry standards, these three new Standards significantly change the design, testing, rental, use and training requirements associated with MEWPs. The Standards also offer greater clarity to the assigned responsibilities associated with these functions to various entities including manufacturer, dealer, owner, user, supervisors, operator, occupants, lessor, lessee and brokers. Compliance with these voluntary standards became effective June 1, 2020.3

Recognized hazards associated with MEWPs include: tip overs associated with wind loads and contact with other obstacles, contact with power lines leading to electrocutions, caught-between the lift and other objects, falls from platform and equipment collapse.4 This effort will analyze injury data including both fatal and nonfatal incidents associated with MEWPs to better understand the trends and quantifying many of the risks associated with the operation and maintenance of MEWPs. Injury data from the U.S. Bureau of Labor and Statistics (BLS) will be reviewed. The effort will also identify and explore how the design, use and training requirements introduced in the new industry standards address the hazards and risk associated with MEWPs.
