Pressure testing using compressed air.
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. Rhoten:
This is in response to your April 17 letter to Mr. Jim E. Lapping, referencing a question concerning whether there is "... any Federal Occupational Safety and Health Administration (OSHA) requirement that addresses the use of compressed air to test for leaks in gas lines?"
