The dead load increases with the height of the scaffold. Scaffold platforms above one section high must be provided with safe access. It should do all of this without settling or any displacement whatsoever. Natural or synthetic rope involved in the suspension scaffold setup should be monitored. A competent person must produce a specific design if the erection does not comply with the guidelines of the scaffolding manufacturer. Inefficient platforms and falling are the top causes. A competent person must produce a specific design if the erection does not comply with the guidelines of the scaffolding manufacturer. Scaffolding designers have a duty to design scaffolding that is safe to manufacture, assemble and use for the purpose it was designed for. The purpose of a working scaffold is to provide a safe place of work with safe access suitable for the work being done. Performance Requirements and General Design.
