3/19/2024 0 Comments Wood scaffolding planksIf the use of plywood over wood planks results in a scaffold (and each scaffold component) designed by a qualified person that meets the capacity requirements with a deflection of no more than 1/60 of the span when loaded, it would meet the performance requirements of Subpart L. Subpart L does not mandate a particular material to be used for a scaffold deck. The requirements for scaffold platforms are written to allow flexibility of design by a qualified person, so long as they meet all the applicable criteria. (16) Platforms shall not deflect more than 1/60 of the span when loaded.Įmployers must ensure that scaffolds are designed, erected, and maintained in accordance with the applicable provisions of Subpart L of Part 1926. (1) Scaffolds and scaffold components shall not be loaded in excess of their maximum intended loads or rated capacities, whichever is less. (i) Each platform unit ( e.g., scaffold plank, fabricated plank, fabricated deck, or fabricated platform) shall be installed so that the space between adjacent units and the space between the platform and the uprights is no more than 1 inch wide, except where the employer can demonstrate that a wider space is necessary. (1) Each platform on all working levels of scaffolds shall be fully planked or decked between the uprights and the guardrail supports as follows: 451(b)(1)(i) provides: (b) Scaffold platform construction. Non-mandatory Appendix A to this subpart contains examples of criteria that will enable an employer to comply with paragraph (a) of this section. (6) Scaffolds shall be designed by a qualified person and shall be constructed and loaded in accordance with that design. ach 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. Qualified means one who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated his/her ability to solve or resolve problems related to the subject matter, the work, or the project. Platforms can be constructed using individual wood planks, fabricated planks, fabricated decks, and fabricated platforms. Platform means a work surface elevated above lower levels. OSHA's construction industry standards addressing scaffolds are in 29 CFR Part 1926, Subpart L.įabricated decking and planking means manufactured platforms made of wood (including laminated wood, and solid sawn wood planks), metal or other materials. Question (1): Does the OSHA scaffold standard for construction (Part 1926 Subpart L) allow for the use of 5/8'' four-ply exterior grade plywood to be used as decking over wood support planks on a combination of tube and coupler, frame, and systems type scaffold?Īnswer: It is permissible, under certain conditions, to use plywood as platform decking material. We have paraphrased your question as follows: We apologize for the delay in responding. Your question relates to the use of plywood as platform decking over wood scaffold planks. This is in response to your fax submitted October 21, 2005, to the Occupational Safety and Health Administration (OSHA).
