Maxim Crane Works is a nationwide crane rental company. In April 2017, a Maxim employee was injured when he fell while disassembling a crane at Maxim’s maintenance yard in Ridley Park, Pennsylvania. As a result of the incident, the Occupational Safety and Health Administration inspected the yard and issued Maxim a two-item serious citation with a total proposed penalty of $25,350. Following a hearing, Chief Administrative Law Judge Covette Rooney affirmed both citation items and assessed the proposed penalty for each violation. Only Item 1, alleging a fall protection violation of 29 C.F.R. § 1910.28(b)(1)(i), is at issue before the Commission. For the reasons discussed below, we affirm the citation.
