Use of Electrical Equipment
Self Inspection Checklist


Guidelines: This checklist covers regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under 29 CFR 1910.334. It applies to all electrical use systems. This checklist does not apply to qualified persons working on installations in vehicles and generation, transmission, distribution, communications, and railway installations. The regulations cited apply only to private employers and their employees, unless adopted by a State agency and applied to other groups such as public employees. A yes answer to a question indicates that this portion of the inspection complies with the OSHA or EPA standard, or with a nonregulatory recommendation. Definitions of terms in bold type are provided at the end of the checklist.

    or damaged item removed from service and are students
    and teachers prohibited from using it until repairs and
    tests have been made? [29 CFR 1910.334(a)(2)(ii)]

 Y   N   N/A   ?? 

  1. Is it prohibited to connect or alter attachment plugs or
    receptacles in any way that would prevent proper
    continuity of the equipment grounding conductor at the
    point where the plugs are attached to the receptacles?
    [29 CFR 1910.334(a)(3)(ii)]
 Y   N   N/A   ?? 

  1. Is it prohibited to alter these devices to allow the grounding
    pole of the plug to be inserted into slots intended for
    connections to the current-carrying conductors?
    [29 CFR 1910.334(a)(3)(ii)]
 Y   N   N/A   ?? 

  1. Are adapters that interrupt the continuity of the equipment
    grounding connection prohibited?
    [29 CFR 1910.334(a)(3)(iii)]
 Y   N   N/A   ?? 

  1. Are only approved portable electric equipment and flexible
    cords used in highly conductive work locations (such as
    those wet with water or other conductive liquids), or in job
    locations where students are likely to contact water or
    conductive liquids? [29 CFR 1910.334(a)(4)]

    Note: Ground-fault circuit interrupters are recommended
    in these situations.
 Y   N   N/A   ?? 

  1. Are students and teachers required to dry their hands when
    plugging and unplugging flexible cords and plug-connected
    equipment if energized equipment is involved?
    [29 CFR 1910.334(a)(5)(i)]
 Y   N   N/A   ?? 

  1. Are energized plug and receptacle connections handled only
    with insulating protective equipment if the connection could
    provide a conducting path to the student's hand (if, for
    example, a cord connector is wet from being immersed in
    water)? [29 CFR 1910.334(a)(5)(ii)]
 Y   N   N/A   ?? 

  1. Are locking-type connectors properly secured
    after connection? [29 CFR 1910.334(a)(5)(iii)]
 Y   N   N/A   ?? 
Electric Power and Lighting Circuits

  1. Are load-rated switches, circuit breakers, or other devices
    designed to be a disconnecting means used for opening,
    reversing, or closing of circuits under load conditions?
    [29 CFR 1910.334(b)(1)]

    Note: Only cable connectors of the load-break type, fuses,
    terminal lugs, and cable splice connections may be used for
    such purposes, except in emergency.
 Y   N   N/A   ?? 

  1. After a circuit is deenergized by a circuit protective device,
    is manually reenergizing the circuit prohibited until it is

Definitions:

Ground-fault circuit-interrupter: a device whose function is to interrupt the electric circuit to the load when a fault current to the ground exceeds a predetermined value that is less than that required to operate the overcurrent protective device of the supply circuit.

Qualified person: one familiar with the construction and operation of the equipment and the hazards involved. Whether a teacher or student is considered a qualified person depends on various circumstances in the workplace. A person may be considered qualified with regard to certain equipment in the workplace, but unqualified as to other equipment. A person who, in the course of on-the-job training, demonstrates an ability to perform duties safely at his or her level of training and who is under the direct supervision of a qualified person is considered to be qualified for the performance of those duties.
