Abstract: At approximately 11:20 a.m. on April 18, 1995, Employee #1, of DeSilva-Gates Construction, was operating a D9 bulldozer at the Pittsburg construction site. He was part of the employer's crew that was rough grading, pad developing, and asphalting. While bulldozing dirt off the edge of a hill, the bulldozer slid backward down the hill. Employee #1 unbuckled and started to jump out but decided not to try it. The bulldozer hit a rocky area downhill and rolled over about 2 1/2 times before stopping. Employee #1 was able to climb out of the cab. He was taken to Mt. Diablo Hospital, Concord, with tailbone fractures, a broken sacrum, and two compressed vertebrae.
