On June 18, 2019, at approximately 4:10 p.m., an employee was preparing a conveyor system to discharge kiln-dried concrete blocks to the tumbler line. The employee was attempting to correct a misaligned photo sensor when a different sensor eye was covered, causing the machine to cycle. As the machine cycled, the push arm swung out and pinned the employee between the pusher and the block turnover frame. The employee was hospitalized with a pelvic fracture. The machine was not locked out/tagged out at the time of the incident.
