Construction methods, construction safety, fall protection: Worker is attaching stanchions on edge of precast hollow core concrete slabs and steel beam top flanges at roof perimeter of 5-story building. Wire cables will be run at top and midheight of stanchions to provide fall protection to construction workers on roof, in parallel with the cables shown on the perimeter of 5th floor below. However, worker erecting stanchions does not himself have any fall protection, though working at roof edge ~60 ft above the ground. In addition, there may be snow/ice patches on the roof this cold February week. Ann Arbor, Michigan, February 2006.
