Abstract: At approximately 8:15 a.m. on Tuesday, July 27, 2010, Employee #1 was working as a painter at a single-story suite in a commercial property in San Diego, CA, that was being remodeled. The interior of the suite included an office space with a drop ceiling and a warehouse in the rear with a high ceiling. Employee #1 was painting the interior warehouse walls. There was a large rolling scaffold inside the warehouse, and employees used ladders to get onto the drop ceiling. There were wood beams in the drop ceiling, but the spaces between the beams, where the ceiling panels were located, did not support any weight. When Employee #1 stepped onto one of the ceiling panels in the interior drop ceiling, he broke through it, falling 8.5 feet onto the carpeted floor of the hallway below. He sustained a dislocation of his thumb and a head laceration in the fall. He was transported to Kaiser Hospital, where he was hospitalized for more than twenty-four hours.
