|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.|
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 at of at least 100 pounds (445 n) for guardrail systems installed on single-point adjustable suspension scaffolds, and at least 200 pounds (890 n) for guardrail systems installed on all other scaffolds.Similarly, you state that the results show that the support brackets, when anchored to simulate field connections, meet a 4:1 safety factor when the specified maximum load of 500 lbs is applied. The 4:1 safety factor is required by §1926.451(a), Capacity, which states:
Except as provided in paragraphs (a)(2), (a)(3), (a)(4), (a)(5), and (g) of this section, 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.We do not have the resources to independently assess the test results. However, if accurate, the test results indicate that these strength requirements have been met.
