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. Schenck:

This is in response to your letter of June 30, 1975 to Assistant Secretary John H. Stender petitioning for the modification of 29 CFR 1910.1017(b)(6), (formerly 29 CFR 1910.93(b)(6) recodified May 28, 1975), Exposure to Vinyl Chloride, Occupational Safety and Health Standards.

29 CFR 1910.1017(b)(6) defines a fabricated product as being one which is "made wholly or partly from polyvinyl chloride, and which does not require further processing at temperatures, and for times, sufficient to cause mass melting of the polyvinyl chloride resulting in the release of vinyl chloride."

"Release of vinyl chloride" means the release of an amount of vinyl chloride which would likely result in employee exposure at or above the action level without regard to the use of engineering controls. Products which can be classified as fabricated products are exempt from the provisions of the vinyl chloride standard. All other products are subject to the requirements of the standard.

There are no plans presently to formally modify the vinyl chloride standard. Therefore, we hope that the above clarification of the regulation will satisfy your petition request.

Should you have further questions, please contact me or members of my staff.

Associate Assistant
Secretary for Regional Programs
