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. Karpin:

This is in response to your letter of September 12, regarding interpretation of the Occupational Safety and Health Administration's (OSHA) Laboratory Standard, 29 CFR 1910.1450.

Per telephone conversation with our staff member Ms. Li, you were informed that laboratories meeting the standard's definitions of "laboratory scale" and "laboratory use" are covered under the standard. Most quality control laboratories are not expected to meet the qualification for coverage under the standard. They are usually adjuncts of production operations which typically perform repetitive procedures for the purpose of assuring reliability of a product or a process. Laboratories that conduct research and development and related analytical work are subject to the requirements of the Laboratory Standard, regardless of whether or not they are used only for support of the manufacturing of CONAP products.

We hope we have adequately addressed your concerns. If you need further assistance, please do not hesitate to contact us again.
