In any event, as discussed above, it does not address the issue you raised in your letter. However, the scaffold standard for which that variance was issued is no longer in effect a new scaffold standard was issued in September 1996. Since OSHA has never modified or revoked it, under section 6(d) of the Occupational Safety and Health Act, it is technically still in effect. You also ask whether that variance is still in effect. It merely noted that, "all planks shall be secured from movement or overlapped in accordance with §1926.451(a)(12)." Like the current standard, the 1975 standard did not address this issue (section 1926.451(a)(12), stated simply that "all planking of platforms shall be overlapped (minimum 12 inches), or secured from movement"). After reviewing the variance and the scaffolding standard that was in effect in 1975, we have determined that the variance did not address this issue. Therefore, both methods are acceptable ways of overlapping planks.ĭuring a telephone conversation, you indicated that you believed that a variance issued on April 4, 1975, for tank scaffolds discussed how scaffold planks should be overlapped, as per your first question. Section 1926.451(b)(7) states, "on scaffolds where platforms are overlapped to create a long platform, the overlap shall occur only over supports, and shall not be less than 12 inches (30 cm) unless the platforms are nailed together or otherwise restrained to prevent movement." The standard does not specify whether both ends of each plank must overlap the same way. When the other end of the 2x4 slipped off. There were no guardrails at the working level. While sitting or kneeling on a fixed deck plank attached to a fabricated frame scaffold, a worker was pulling a 16-foot long 2x4 off the bucket of an excavator. ![]() Your question is whether both ways are acceptable. The scaffold was not secured to wooden footing supports, nor was it tied to the building. The second drawing shows the planks laid so that both ends of each plank are either on the bottom or the top of their respective overlaps (using this second methods each plank lays flat). In one drawing, the planks are laid so that one end of each plank is on the bottom of an overlap and the other end is on the top of an overlap (using this method the planks are slightly tilted). In both methods the ends of each scaffolding plank are overlapped with the ends of the adjacent planks. In the diagram that you sent to our office, you show two ways of installing end-to-end rows of scaffolding planks. This is in response to your Jletter in which you ask for clarification on tank scaffolding planking and if a variance issued on April 4, 1975, is still in effect.
