Abstract: On November 22, 2005, Employee #1 was working at Monrovia Growers, a wholesale distributor of flowers and associated supplies in Azusa, CA. One of his coworkers had parked a company truck on an incline in a dirt road. The coworker didn't set the parking brake, because it had not worked for a few months. He attempted to put the manual transmission in first gear but instead put it in neutral. With the transmission in neutral and no parking brake, the truck became a runaway vehicle and rolled down the dirt road. The truck ran into an employee restroom building, where Employee #1 was inside cleaning. The building collapsed and fell on Employee #1's left leg. Employee #1 sustained a bone fracture in his left knee. He was not hospitalized.
