|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.|
(g) Fall protection. Each employee on a scaffold more than 10 feet (3.1 m) above a lower level shall be protected from falling to that lower level ....Section 1926.451(h) that covers Falling object protection states:
* * * * *
(4) Guardrail systems installed to meet the requirements of this section shall comply with the following provisions (guardrail systems built in accordance with Appendix A to this subpart will be deemed to meet the requirements of paragraphs (g)(4)(vii), (viii), and (ix) of this section):
* * * * *
(v) When screens and mesh are used, they shall extend from the top edge of the guardrail system to the scaffold platform, and along the entire opening between the supports .... [Emphasis added.]
* * *Finally, Non-Mandatory Appendix A to Subpart L of Part 1926 Scaffold Specifications provides in part:
(h) Falling object protection. (1) In addition to wearing hardhats each employee on a scaffold shall be provided with additional protection from falling hand tools, debris, and other small objects through the installation of toeboards, screens, or guardrail systems, or through the erection of debris nets, catch platforms, or canopy structures that contain or deflect the falling objects.
* * *
(2) Where there is a danger of tools, materials, or equipment falling from a scaffold and striking employees below, the following provisions apply:
* * *
(iii) Where tools, materials, or equipment are piled to a height higher than the top edge of the toeboard, paneling or screening extending from the toeboard or platform to the top of the guardrail shall be erected for a distance sufficient to protect employees below; or [Emphasis added.]
* * *The two provisions noted above from §1926.451 paragraphs (g)(4)(v) and (h)(2)(iii) are requirements in Subpart L while paragraph 1.(f) is in the Non-Mandatory Appendix to the subpart. The paragraphs from the standard, (g)(4)(v) and (h)(2)(iii), address different hazards (fall hazards to workers and falling objects, respectively) and, as such, do not actually conflict with each other in prescribing the use of screens. Nonetheless, it should be noted that the variations in the wording relate to their different purposes.
This Appendix provides non-mandatory guidelines to assist employers in complying with the requirements of subpart L of this part. An employer may use these guidelines and tables as a starting point for designing scaffold systems. However, the guidelines do not provide all the information necessary to build a complete system, and the employer is still responsible for designing and assembling these components in such a way that the completed system will meet the requirements of §1926.451(a).

* * *
(f) Screen installed between toeboards and midrails or toprails shall consist of No. 18 gauge U.S. Standard wire 1-inch mesh. [Emphasis added.]
