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. Schepke:

This is in response to your recent letter concerning OSHA requirements on fixed ladders relating to communication towers.

Communication towers equipped with fixed ladders, over 20 feet in unbroken length, are required to be protected by a ladder safety device or cage and landing platforms as indicated in 29 CFR 1910.27(d).

If we may be of further assistance, please call or write.
