The preeminent safety standard for elevators (mechanical and hydraulic) has been developed by the American Society of Mechanical Engineers (ASME A17.3-2011) and has been adopted by The Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI). Contractors perform all maintenance and service work on university elevators; OSU employees are not permitted to conduct maintenance or service. Contractors preforming maintenance or service work on any of OSU’s elevators are expected to know and follow all of the applications and practices contained in ASME A17.3-2011.
