Abstract: At approximately 3:00 a.m. on February 20, 2005, Employee #1, a janitor at a frozen food manufacturing facility, was cleaning a three-roll sheeter. Following the same process as the adjacent janitor, Employee #1 removed the covers from the sheeter, exposing the chain and sprocket. The machine was not locked out and tagged out at that time. Employee #1's sleeve became caught on the chain and his arm was pulled into the machine. A coworker heard Employee #1 scream and shut the line down. The Employee #1 was transported to Northridge Medical, and then hospitalized at LA County USC Medical Center for crushing injuries to his hand and forearm.
