A safety system comprising a seat board assembly and an associated harness to be worn by a person located at an elevated position for releasable securement to a holding device to protect the person from falling. The harness is formed of interconnected webs of flexible, e.g., nylon, material. The seat board assembly includes a generally planar panel which is arranged to be releasably secured to the harness for supporting the person's buttocks thereon so that he or she may move about relatively unencumbered by the system. The system also includes a pair of extendable, flexible, repelling straps for connection to a lowering device mounting on an adjacent safety line to enable the person to repel down the line. The seat board panel has a pair of flexible connecting straps projecting from opposed sides thereof for releasable securment, e.g., via VELCRO fasteners, to respective buckles on the harness to suspend the seat board panel below the harness.
