Abstract: On January 30, 2008, Employee #1 with Western Wood Treating, Inc. of Woodland and another mechanic were preparing to work on bearings associated with a steel retort door. In order to address the bearings, the door pin needed to be moved and a bottle jack was brought over to assist in moving the pin. Two 4 by 6 inch boards were placed on the retort super structure and the jack placed onto the boards. To reach the door pin, a solid rod was placed between the jack head and bottom of the door pin. The jack was raised a little but stopped when resistance was reached. Another employee began striking the door pin with a hammer when the jack suddenly kicked out and struck Employee #1 in the stomach. The Woodland Fire Department responded and Employee #1 was transported to UC Davis Medical Center in Sacramento. Employee #1 underwent surgery to address gastrointestinal (GI) trauma and was released on February 4, 2008.
