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.

Dear Mr. Lemma,
This is in response to your letter requesting clarification of the requirement to guard couplings connecting driven power shafts.
According to your letter description and the enclosed pictures which show a sheet metal sleeve bolted to the motor/pump base totally covering the coupling we believe that you are in total compliance with OSHA 1910.219(i)(2) on page 23730 of the Federal Register dated June 27, 1974, Vol. 39, #125. This standard requires that bolts, nuts and setscrews shall either be counter-sunk or covered by a sleeve in the manner you are providing. Accordingly, you may state on your own authority that this particular item meets OSHA standards. You may not state the item is approved by OSHA.
We have mailed under separate cover several OSHA brochures including the above noted Federal Register. Please feel free to contact us if there are further questions about OSHA.
