Abstract: At approximately 2:45 a.m. on November 6, 1992, Employee #1, of The Sacramento Bee newspaper, was moving a loaded cart of newspapers, which weighed more than 800 lb, from a bundling machine to truck loading docks. While moving the cart through a constricted area, her left thumb became caught between the cart and a conveyor crossover stairway. Her thumb struck the steel support beam of the stairway between the first and second joint, crushing and lacerating the tissue. Employee #1 was given first aid and then transported to Sutter General Hospital, Sacramento, CA. The thumb was operated on and the bone fragments were placed back together.
