Abstract: At 1:00 p.m. on September 9, 2015, a 20-year-old male employed by a window cleaning services company fell approximately 58.8 feet to the ground. The employee was performing drop work by cleaning exterior windows of a senior living commercial property. The employee was descending from the Rooftop Rigger and was attached to a safety life line and descent device. The employee had just moved the Rooftop Rigger to a new location in order to clean another row of windows. The Rooftop Rigger was not tied back to a separate anchor point. The counterweights were not utilized prior to the employee going over the edge. A co-worker was working on the row of windows next to the employee, and had briefly seen a glimpse of the top of the roof rigger while cleaning windows. The co-worker then noticed when the employee went to sit in the boatswain's chair, the tip of the roof rigger bent down farther than normal and eventually fell over the side of the building. The employee was able to hold on to the roof edge for a brief period of time before being catapulted to the ground. The employee was transported to a local hospital where he was later pronounced dead. He sustained blunt force injuries of the neck.
