Dear Mr. Blocher:
Thank you for your letter of January 23, requesting clarification on the applicability of 29 CFR 1910 Subpart S, Electrical standards, to desktop computers.
Desktop computers are "appliances" otherwise described as "utilization equipment" when used by employees in the workplace. By 29 CFR 1910.303(a) "equipment" required or permitted by 29 CFR 1910 Subpart S shall be "accepted" only if "approved". "Approved" means acceptable to the authority, that is, the Assistant Secretary of Labor for Occupational Safety and Health, enforcing 29 CFR 1910 Subpart S. The definition of "acceptable" includes three different methods to determine acceptable equipment, and these methods are specified at 1910.399. A copy of the 1910.399 definitions, specified by quotation marks in this letter, is enclosed for your use.
We appreciate your interest in occupational safety and health. If we can be of further assistance, please do not hesitate to contact us.
Patricia K. Clark, Director
Directorate of Compliance Programs
