Structural steel ironworker arc welds corrugated steel deck to beams at periphery of floor opening. Standing ironworker is holding a steel angle iron to be welded in corner to provide support for perimeter cable fall protection (see the other two corners). Ross School of Business, University of Michigan, Ann Arbor. January, 2007.
Steel erection fall protection: Structural steel ironworker on left has fall protection from full body harness attached to safety lanyard attached to steel cable loop/sling around girder as he moves from left to right along wide flange structural steel girderl Here, he liftis cable loop/sling past steel plate attachment that will support far end of a steel floor beam/joist. Ironworker on right his apparently without fall protection, with one safety lanyard attached from cable loop/sling that hangs loose and other end attached to lower ring on his body harness. However, his second lanyard could be attached to a sliding beam flange anchor attached to top flange of girder. Ross School of Business, University of Michigan, Ann Arbor. January, 2007.
Steel erection fall protection: Structural steel ironworker straddles wide flange structural steel beam. Fall protection provided by full body harness attached to safety lanyard attached to steel cable loop/sling around beam. Ross School of Business, University of Michigan, Ann Arbor. January, 2007.
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.
Concrete and structural steel construction: Three cranes and a personnel lift operating in same area. On right, Grove mobile telescoping hydraulic crane lowers concrete bucket to place concrete. On left, another Grove mobile telescoping hydraulic crane is not currently operating, so it supports concrete masonry unit deadweight. In left center of photo, corrugated galvanized steel decking is being raised by unseen tower crane to be erected on steel frame to left. In center, Genie personnel lift supports an ironworker. Cardiovascular Center, University of Michigan Hospital, Ann Arbor, 2004.

Steel construction safety. Two structural ironworker erectors wait to receive next structural steel beam to erect. Workers are supported by JLG electric boom lifts that are controlled from worker platform. Boom lifts platforms and guardrails provide ironworkers with a safe, productive work environment from which to perform high quality construction. Ann Arbor, 2004.
Steel construction safety: Two structural ironworker erectors place erection bolts for wide flange steel beam. Ironworkers are supported by JLG electric boom lifts that are controlled from worker platform. The lift platform and guardrail provide primary fall protection to the ironworkers, and the Ironworkers also have personal fall protection from lanyardsbetween body harness and lift guardrail. Ann Arbor, 2004.
