Atlas began the window cleaning project at Diamond-Star at the north end. When the accident occurred, approximately three-quarters of the windows had been cleaned. Cockrum worked cleaning the windows from the inside and outside. The ladder Cockrum was using when the accident occurred was his personal ladder which his employer had borrowed sometimes for jobs. It was a 24-foot aluminum extension ladder. Cockrum had seen other people using aluminum ladders to clean the windows at Diamond-Star. Other people used Cockrum's ladder and he used it for other jobs he performed while working forAtlas.
Butch Jackson worked with Cockrum the day of the accident. Jackson was using one portion of a 28-foot ladder owned by Atlas. Cockrum was using both portions of his ladder. He testified it was his employer, Bernstein, who decided whether to use a ladder to wash the windows. No Kajima employee told him to use a ladder or that he could not use other means to clean the windows. Cockrum testified Bernstein had rented a "boom" to clean windows at a bank on one occasion and he had used the device where he was in a "bucket" on another occasion.
The day the accident occurred, Cockrum arrived at Diamond-Star at 8 a.m. or 9 a.m. He signed in at the security gate. Other people were working at the plant
