|OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.|
Except as provided in..., 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.Section 1926.451(a)(6) states in part:
...Non-mandatory Appendix A to this subpart contains examples of criteria that will enable an employer to comply with paragraph (a) of this section.Fall protection criteria are set forth in §1926.451(g)(4). Among other requirements, that provision provides:
* * * * *Finally, the falling object protection provision in §1926.451(h)(4)(i) that you refer to states:
(vii) Each toprail or equivalent member of a guardrail system shall be capable of withstanding, without failure, a force applied in any downward or horizontal direction at any point along its top edge of at least 100 pounds (445 n) for guardrail systems installed on single-point adjustable suspension scaffolds or two-point adjustable suspension scaffolds, and at least 200 pounds (890 n) for guardrail systems installed on all other scaffolds.
* * * * *
(ix) Midrails, screens, mesh, intermediate vertical members, solid panels, and equivalent structural members of a guardrail system shall be capable of withstanding, without failure, a force applied in any downward or horizontal direction at any point along the midrail or other member of at least 75 pounds (333 n) for guardrail systems with a minimum of 100 pound toprail capacity and a minimum 200 pound toprail capacity.
* * * * *
When used, toeboards shall be capable of withstanding, without failure, a force of at least 50 pounds (220 n) applied in any downward or horizontal direction at any point along the toeboard...Although these provisions do not address whether a load greater than these minimum strength requirements may be applied, §1926.451(f)(1) does address that question:
Scaffolds and scaffold components shall not be loaded in excess of their maximum intended loads or rated capacities, whichever is less.A load greater than the applicable minimum strength requirement is permitted to be applied only to the extent the scaffold's (and scaffold component's) design strength exceeds the applicable requirement. In no case, is it permissible to load scaffolds and scaffold components in excess of their maximum intended loads or rated capacities, whichever are less.
