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.

Dear Mr. Hovi:
Thank you for your letter of May 16, concerning wire rope perimeter guarding for open-sided floors. Please excuse the delay in response.
The Occupational Safety and Health Administration (OSHA) requirements for perimeter guarding are specified in 29 CFR 1926. When wire rope is used as an alternate to the specified perimeter guarding techniques of 29 CFR 1926.500(d)(1) and (f)(1), it becomes the responsibility of the employer to show that the installation provides equivalent protection for the employees. Normally, inspection and certification of the installation by a registered professional engineer is acceptable to verify equivalency.
It is our opinion that the example noted by your letter is not likely to provide equivalency to the requirements of the standard and could create a false sense of safety which in turn creates a greater hazard to workers.
If we may be of further assistance, please contact us.
Gerald F. Reidy, Director
Office of Construction and Maritime Compliance Assistance
