Abstract: At approximately 2:15 p.m. on June 25, 2012, an employee, of Capitol Neon, an electrical contractor, was working at a commercial building site in Elk Grove, CA. He was working on the building's front, painting while positioned in the basket of a Phoenix-Sky Hoist SX aerial lift with a 60-foot boom mounted on the bed of a Chevrolet C6500 truck. The bolts securing the aerial lift's turntable to the truck failed, causing the boom and employee-occupied basket to crash approximately 14 feet to the concrete below. The employee was wearing a personal fall arrest system and remained in the basket throughout the fall. He was transported by ambulance to Kaiser-Permanente South Medical Center, where he was admitted and treated for multiple fractures and dislocation of his left ankle. He was discharged at approximately 12:00 p.m. on June 27, 2012. The employer reported this accident to the nearest Cal/OSHA Enforcement Office.
