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. Butterfield:
This is in response to your letter of October 13, 1989 and to your second letter on the same subject dated December 29, 1989. Please accept my apology for the delay in response.
Your letters requested a clarification as to whether the members of your association are subject to the provisions of 29 CFR 1910.147, Control of Hazardous Energy Sources (lockout/tagout). A specific reference was made to the section of the standard that excludes the construction industry.
The manufactured home builders, which you indicate as your membership, is listed under Standard Industrial Classification (SIC) code 2451. While engaged in the manufacturing activities of this SIC code, the employees of your member manufacturing plants are afforded the protections under the "lockout/tagout" standard referenced above.
I hope this provides you with the information you requested. If you have any further questions, please contact me. Thank you for your interest in occupational safety and health.
Thomas J. Shepich, Director
Directorate of Compliance Programs
