Dear Mr. Moore:
This is in response to your letter of October 11, 1984, concerning the strength criteria for guardrail and stairway systems. This also confirms your telephone conversation on October 18, 1984 with a member of my staff, Mr. Simms.
29 CFR 1926.500(f)(iv) requires that the anchoring of posts and framing of members for railings of all types shall be of such construction that the completed structure shall be capable of withstanding a load of at least 200 pounds applied in any direction at any point on the top rail, with a minimum of deflection.
Based on the information you provided in your letter it appears that you must use a pipe greater than 1-1/4" to comply with the above mentioned minimum design criteria.
If I may be of further assistance, please let me know.
John B. Miles, Jr., Director
Directorate of Field Operations
