Abstract: At approximately 7:30 a.m. on September 2, 2000, Employee #1 and coworkers were clearing a jam in the calendar rolls of the #1 paper machine. They had just lifted the four calendar rolls when the journal ends of the #4 roll broke, ejecting it back out of the stack horizontally and toward the catwalk where Employee #1 was standing. The roll demolished the catwalk and crushed Employee #1 against the calender drier roll on the opposite side of the walkway. He sustained severe crushing injuries and was transported to the hospital, where he died on October 25, 2000. During normal operations, the #1 paper machine ran the product smoothly through the calendar rolls at the front of the machine, after which the king and queen driver rolls smoothed the paper to its desired thickness. On this occasion, as apparently occurred with some frequency, the paper broke and had wrapped around one of the rolls.
