Why are the Appendices to the Subpart L Scaffolding standards important? Do they address standard requirements?
All of the appendices are non-mandatory and contain selection criteria for planks; American National Standards Institute (ANSI) standard references for aerial lifts; criteria for determining the feasibility of providing safe access and fall protection, and training for erectors and dismantlers; and drawings of various types of scaffolds and components.
To summarize, Appendix A of Subpart L addresses scaffold specifications and provides non-mandatory guidelines to assist employers in complying with Subpart L requirements. These guidelines and tables provide a starting point for designing scaffold systems; however, they do not provide all the information necessary to build a complete system. Therefore, the employer is still responsible for designing and assembling these components so that the completed system meets the final rule requirements in 1926.451(a).
