• Key terms are defined in this section.

Labeled: Equipment is labeled if there is attached to it a label, symbol, or other identifying mark of a nationally recognized testing laboratory: (1) That makes periodic inspections of the production of such equipment, and (2) Whose labeling indicates compliance with nationally recognized standards or tests to determine safe use in a specified manner.

Listed: Equipment is listed if it is of a kind mentioned in a list that: (1) Is published by a nationally recognized laboratory that makes periodic inspection of the production of such equipment, and (2) States that such equipment meets nationally recognized standards or has been tested and found safe for use in a specified manner.

Qualified person: A qualified person is someone who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment and installations and the hazards involved. Whether an employee is considered a “qualified person” will depend upon various circumstances in the workplace. For example, it is possible and, in fact, likely for an individual to be considered qualified with regard to certain equipment in the workplace, but unqualified as to other equipment. (See 1910.332(b)(3) for training requirements that specifically apply to qualified persons.) An employee who is undergoing on-the-job training and who, in the course of such training, has demonstrated an ability to perform duties safely at their level of training and who is under the direct supervision of a qualified person is considered a qualified person for the performance of those duties.

Readily accessible: Something that is capable of being reached quickly for operation, renewal, or inspections, so that those needing ready access do not have to climb over or remove obstacles or to resort to portable ladders, chairs, etc.
