Section 1926.451(a)(6) continues: Scaffolds shall be designed by a qualified person and shall be constructed in accordance with that design. , each scaffold and scaffold component shall be capable of supporting, without failure, its own weight and at least 4 times the maximum intended load applied or transmitted to it. General scaffold requirements are set forth in §1926.451. Section 1926.450(b) defines "Fabricated decking and planking" as: manufactured platform made of wood (including laminated wood, and solid sawn wood planks), metal or other materials. That definition, in part, provides: Platforms can be constructed using individual wood planks, fabricated planks, fabricated decks, and fabricated platforms. "Platform," which form the working surfaces of scaffolds, are defined in §1926.451(b). OSHA's construction industry standards addressing scaffolds are in 29 CFR Part 1926 Subpart L. It is permissible under certain conditions to use plywood as platform decking material. Do OSHA standards prohibit the use of plywood as a platform decking material? Question (1)(a): In the course of building supported scaffolds (such as tube-and-coupler), our construction company sometimes uses plywood to build large area scaffolds, as well as to cover gaps in scaffolds that result from protruding pipes and structures. We have paraphrased your questions as below: Your letter was forwarded to this office for handling on April 1, 2004. You ask about the requirements in 29 CFR Part 1926 Subpart L (Scaffolds) regarding the use of plywood to make platform decking for scaffolds. This is in response to your letter dated March 3, 2004, to the Occupational Safety and Health Administration (OSHA). Re: Whether plywood may be used to make platform decking for scaffolds under Part 1926 Subpart L (Scaffolds), and if so, whether the information in Table 7-3 of American Concrete Institute Committee SP-4 Formwork for Concrete (Fourth Edition) can be used as a guide in designing scaffold platforms? §1926.451(a)(1) and 1926.451(6), 1926.451(b), and 1926.451(f)
