In September 2016, an employee of Wayne Farms, LLC, sustained serious injuries to his right arm and hand while working on a breading machine at the company’s poultry processing facility in Decatur, Alabama. Following the incident, the Occupational Safety and Health Administration conducted an inspection and issued Wayne Farms a one-item serious citation alleging a violation of 29 C.F.R. § 1910.212(a)(1) for failing to guard the “sprocket and chain system” on the breading machine. Following a hearing, Judge Sharon D. Calhoun vacated the citation for lack of employee exposure to the alleged violative condition. For the reasons discussed below, we also vacate the citation.
