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.

| MEMORANDUM FOR: | JOHN GRANCHI Associate Assistant Regional Director for Technical Support |
| SUBJECT: | Field Information Memorandum #74-39 Requests for Standards Interpretation |
This is in response to your letter of May 24, 1974 and the attachment from Naramore Bain Brady and Johanson, dated May 10, 1974.
If a stairway were intended for employee use only, the provisions of part 1910.23(d) would be applicable. The design of stairways wider than 88 inches without an intermediate stair railing, in buildings intended primarily for public use as described in the architects' letter, does not fall within the purview of OSHA.
