Abstract: At approximately 8:40 a.m. on July 24, 2003, Employee #1 and several coworkers were working at the Echeverria Dairy, building the North Cow cover structure. The employees were on the roof of the structure and while Employee #1 was screwing down a metal sheet to the purlin, the coworkers were moving another approximately 50-foot-long by 38-inch-wide sheet into place. The coworkers ran the sheet into the back of the legs of Employee #1. He lost his balance and fell off the leading edge approximately 30 feet to the concrete floor. He was transported by helicopter to Kern Medical Center where he later died.
