Abstract: On February 7, 2007, Employee #1, of Tim Dugan Drywall in Valley Springs, CA, was working with a coworker on the platform of a rolling scaffold. He was approximately 114 inches above the floor. The workers were at opposite ends of the rolling scaffold and had finished taping around ceiling-mounted lighting. They were squatting on the work platform, which consisted of a single plank, even though the scaffold was approximately 5 feet wide. Two more workers, on the floor, had unlocked the scaffold's wheels and were just beginning to move the scaffold, when Employee #1 fell off the single plank. He hit a cross brace before landing on the concrete floor. The West Sacramento Fire Department responded and arranged to have Employee #1 transported to UC Davis Medical Center in Sacramento. He sustained a laceration to his forehead and was released later that day.
