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 https://www.osha.gov.

Dear Mr. Marr:
Your interpretation of the installation of a peripheral safety railing for decked floors is correct. Section 1926.750(b)(1)(iii) requires the "½-inch wire rope or equal" around planked or decked floors, and we agree that it would be hazardous to install the peripheral safety railing until the decking adjacent to the unprotected outside edge of the floor is in place.
