Abstract: At 4:30 p.m. on December 27, 2019, an employee was working with his supervisor, adjusting the chain tension of elevator 41A. The supervisor was at one end, adjusting the bolt that affects the tension, and the employee was using his gloved hand to push on the chain (while it was moving) to test the tension. As the employee was pushing on the chain, his glove was caught, and his left index finger was pulled into the nip point of the chain and sprocket. The injured employee immediately pulled his left hand back, but the finger pad and the glove tip were pulled off, leaving only exposed bone of the fingertip. The employee sustained an amputation to the left index finger, to the first knuckle. He was treated at Doctors Medical Center in Modesto, CA and hospitalized.
