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. September 8, 1978 Mr. J. A. Torres Division Chief Architect Bechtel Power Corporation P. O. Box 607 15740 Shady Grove Road Gaithersburg, Maryland 20760 Dear Mr. Torres: This is in response to your letter requesting OSHA concurrence on the use of 3/4" square bars for rungs on fixed ladders. A fixed ladder rung configuration using 3/4" square bars with the rungs placed on an angle (flat surfaces are in a 45-degree angle with the ground), satisfying the design requirements in 29 CFR 1910.27(a)(1), meets the requirements of 29 CFR 1910.27(b)(1)(i) of the General Industry Safety and Health Standards. If I may be of any further assistance, please feel free to contact me. Sincerely, John K. Barto, Chief Division of Occupational Safety Programming [Corrected January 22, 2008]
