At approximately 4:00 p.m. on September 25, 2018, Employee # 1 had finished mixing cement for the day. He was cleaning the inside of a marion mixer that was not deenergized, mechanically blocked, or locked out to prevent inadvertent movement, or release of stored energy during cleaning. The mixer's paddles were in the way, so Employee # 1 hit start and stop quickly so the machine would cycle the paddles out of the way. He reached in to remove the excess cement mix with his right hand. Since the machine was still energized, it continued to cycle and a paddle caught and crushed Employee # 1's left hand. Two coworkers (Coworker #1 and #2) heard Employee # 1 yell out in pain, asking for help. Coworker #2 went to help Employee # 1 turn the paddle to free his hand.
