A work platform system for use while working off the ground in new construction, particularly in installed of roof structures and upper floors where fall protection systems are required and for which no effective work platform systems are available. System consists of frame (10, 12, 14, 16, 18) fabricated from standard galvanized light gauge steel components, with brackets (20, 22), clips (26,28,32) and straps (30) fabricated from standard galvanized stock. Components are welded and/or bolted together, Brackets are attached to partially-completed structure to establish work platform for subsequent construction operation. System utilizes conventional scaffold planks and railings. Installation and use are in accordance with existing regulations for working on work platforms. Use of separate fall protection devices is alleviated by use of this system.
