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 Ms. Hansen:
This is in response to your April 7 letter which requested an interpretation of 29 CFR 1910.147(a)(2)(iii)(a) as to what "under the exclusive control of the employee" means with respect to cord and plug connected electric equipment.
"Under the exclusive control of the employee" means that the authorized employee would be able to prevent the equipment from becoming reenergized during his or her servicing or maintenance of that equipment. The plug is under the exclusive control of the employee if it is physically in the possession of the employee, or within arms reach and in line of sight of the employee, or if the employee has affixed a lockout/tagout device on the plug in compliance with the 29 CFR 1910.147.
Thank you for your interest in occupational safety and health. If we can be of further assistance, please contact us.
Roger A. Clark, Director
Directorate of Compliance Programs
