To accomplish this, the scaffold design must incorporate a realistic See Appendix A of Subpart L for non-mandatory toeboard guidelines. Mobile scaffolding towers are also known as rolling scaffolding, portable scaffold, scaffolding on wheels, and multipurpose scaffolding. Before starting any scaffold project, the employer should conduct a hazard assessment to ensure the safety of workers. The drawback to stairways, however, is the amount of space they are likely to take up in the overall structure. After the sign had been partially painted, the scaffold was moved to allow concrete to be placed around the sign. Toeboards must be installed not more than 1/4 inch above the platform and securely fastened. Scaffolds are generally rated as light, medium or heavy duty and must be able to support the correlating weight of workers and materials required for each type. Midrails must be installed at a height approximately midway between the toprail and the platform surface. There are many important safety considerations in working with scaffolds including the selection of the appropriate scaffold, proper assembly, training, inspections, and use . Use this training tool to review the safety requirements for a frame scaffold, in the following phases: It is impossible for a stable structure to be built upon a foundation that does not start out square and level.
