Construction safety, roof construction, demolition: Four roofers at edge of roof, without fall protection, manhandle lifting and tying off flared top of trash chute with which to funnel old roofing material into dump truck for disposal. The crew is using two pitch forks (hand tools for roof demolition) to pry top flared part of chute over and above roof edge and gutter. Worker on right lost his balance an instant before this photo was taken, and in photo he is raising left arm and sitting back with grimace on his face, which saved him from pitching over roof edge and falling two floors. Of course, workers return next day to demolish roof , including near edge, and walk to edge of roof to drop debris into chute. They should all be wearing body harnesses, with lanyards tied back with safety line to a secure support near center of roof. California, 2006.
