An enhanced safety scaffold assembly ( 10 ) is provided including end frames ( 12,14 ) interconnected by means of cross-tie structure ( 18,20 ). The end frames ( 12,14 ) include ledgers ( 36 ) located a safety distance ( 38 ) of at least about thirty inches below the upper ends ( 26 b, 28 b) of the standards ( 26,28 ), and are free of additional ledgers within the safety distance. A platform ( 16 ) is supported by the ledgers ( 36 ), and guardrail assemblies ( 22,24 ) extend between opposed standards ( 26,28 ). In this way, the platform ( 16 ) is located well below the upper ends ( 26 b, 28 b) of the standards ( 26,28 ) in accordance with existing safety regulations, and placement of a platform ( 16 ) in an unsafe, elevated position is precluded. The assemblies of the invention may be constructed in a variety of ways to include optional leveling units ( 58 ), ladders ( 44 ), outriggers ( 134 ) and supplemental work platforms ( 144 ).
