Abstract: At 11:00 a.m. on August 14, 2010, Employee #1 was working for the general contractor CEO Assistant in Los Angeles, CA. Employee #1 had started working that day at 6:00 a.m. at the company yard. After finishing the first delivery and returning to the yard, Employee #1 received the second delivery assignment from the dispatcher. Employee #1 left the yard for the second delivery at 10:00 a.m. and arrived at the site at 10:10 a.m. Upon arrival, Employee #1 met one of the general contractor employees, California Skateparks, at the gate of worksite. Employee #1 walked up the ramp for a visual inspection of the ramp. The ramp appeared to be strong enough to drive the truck on, so Employee #1 decided to drive the cement truck onto the ramp after California Skateparks' employees removed the metal frame from its position across the gate. According to Employee #1's statements, one of the California Skateparks employees helped him to back up the truck onto the ramp. When Employee #1 was almost at the top of the ramp, he heard some cracking noises from underneath the truck. Shortly after that, the back of the truck fell through the ramp, causing the truck's cabin to lift up in the air, with Employee #1 in it. Employee #1 had difficulty getting out of the truck, so employees of California Skateparks came down the ramp to help Employee #1. After a few attempts, Employee #1 managed to get out of the truck cab. He walked to the gate and called his company and his wife. Employee #1's company dispatcher called emergency medical services. Employee #1 was taken to LA County Hospital and was released the same day. Employee #1 was taken to the Cedars-Sinai Medical Center the next morning by his family for further exams, and he was hospitalized for one day. Employee #1 sustained trauma to his neck, back, shoulder, arms, and legs.
