Ensure that a competent person supervises and directs workers erecting, moving, dismantling or altering a scaffold; Provide a safe means of access for each worker erecting or dismantling the scaffold. Scaffolding is naturally unstable because it is usually a tall structure with a narrow base. [, On scaffolds where platforms are abutted to create a long platform, each abutted end must rest on a separate support surface (this does not preclude the use of shared support members such as "T" sections, hook-on platforms that rest on common supports, etc.). Erects scaffolding and ladders for assembling structures above ground level. [, Scaffold components manufactured by different manufacturers must not be intermixed, unless they fit together without being forced and the scaffold's structural integrity is maintained. As one of the fastest growing agencies in California, GDI Insurance Agency, Inc. is able to provide its clients with the latest and greatest of what the insurance industry has to offer and much, much more. The objective is to reduce the tripping hazard by having the ends of the top layer of planks form a straight line, rather than a saw-toothed edge, which increases tripping hazards.
