On October 4, 2019, the Dallas Area Office of the Occupational Safety and Health Administration (“OSHA”) received a report that an employee of Respondent, Walker Industrial, LLC (“Walker”), died as a result of an accident at a warehouse in Irving, Texas. (Ex. J-1, at 3). That same day, OSHA sent Compliance Safety and Health Officer (“CSHO”) Ryan McAliney to inspect the worksite and investigate the cause of the fatality. (Id. at 3). From his investigation, CSHO McAliney learned that another Walker employee, while operating a JLG aerial lift (the “Aerial Lift”), had inadvertently backed into a Genie scissor lift (the “Scissor Lift”) on which three Walker employees were standing while engaged in electric wire pulling activities. (Id.). The force from the Aerial Lift caused the elevated Scissor Lift to fall over sideways to the ground, along with the employees in its basket. (Id.). The three employees all suffered severe injuries, and one of the employees died as a result. (Id. at 2).
