In the USA, our Occupational Safety and Health Administration (OSHA) has an exception to Lockout/Tagout (LOTO) for “cord and plug” equipment. The exception, 1910.147(a)(2)(iii)(A), states:
|
Work on cord and plug-connected electric equipment for which exposure to the hazards of unexpected energization or start-up of the equipment is controlled by the unplugging of the equipment from the energy source AND by the plug being under the exclusive control of the employee performing the servicing or maintenance.
