Abstract: At approximately 8:50 a.m. on June 7, 2002, an employee of MPM Building Services was washing windows using a boatswain's chair when he fell. The employee sustained rope burns to both hands after having fallen about two stories distance down the face of a building, having been saved from the remainder of the fall via his separately attached lifeline. The employee later stated in an interview that he had forgotten to attach the controlled descent apparatus to the line servicing the boatswain's chair. The employee was rescued from the side of the building by Los Angeles County Fire and Rescue and was transported to Arcadia Methodist for treatment. He was hospitalized for burns.
