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.

Sincerely

Thomas J. Shepich, Director
Directorate of Compliance Programs
