Mountain States Contractors, LLC v. Perez, No. 15-3782 (6th Cir. 2016)Annotate this Case
The Tennessee Department of Transportation engaged Mountain States to build two bridges over the Cumberland River at its intersection with Highway 109 in Gallatin. On May 21, 2013, the boom cable of a Terex HC 165 crane snapped while the crane operator was excavating material from under water, causing the boom—the extendable overhead arm of the crane controlled by the load-bearing wire boom cable—to collapse onto the adjacent highway. As the cable broke under tension, it whipped back to shatter the windows of the crane operator’s cab and the boom hit a passing vehicle. Though no person was injured, the subsequent OSHA investigation determined that at least four people were exposed to risk as a result of the accident. An Administrative Law Judge determined that Mountain States had committed a willful violation of the wire rope inspection standard of the Occupational Safety and Health Administration Act because, before the accident, Mountain States had knowledge that the boom cable had “visible broken wires” within the meaning of the provision requiring repair or replacement before further use. The Sixth Circuit affirmed the citation and penalty, finding substantial evidence to support findings of constructive and actual knowledge.
