    POLICY

    A. Purpose

    The Lawrence Berkeley National Laboratory (Berkeley Lab) Electrical Equipment Safety Program (EESP) is designed to ensure the safe operation and installation of electrical utilization equipment. This is achieved by purchasing equipment with a Nationally Recognized Testing Laboratory (NRTL) certification, or through a Berkeley Lab inspection and approval process, with final approval by the Berkeley Lab Electrical Safety Authority Having Jurisdiction (AHJ).

    B. Persons Affected

    Any Berkeley Lab employee, subcontractor, or affiliate who purchases or builds electrical utilization equipment for use at Berkeley Lab that has a potential of 50 volts or greater anywhere in the equipment

    C. Exceptions

    The following types of electrical equipment do not require inspection and approval prior to use:

    1. Unmodified NRTL-Listed Equipment: Equipment that is listed by an NRTL and has not been modified.
    2. Unused Equipment: Equipment that is not being used, e.g., in storage, staged for salvage or excess, etc. Equipment that is not being used must be labeled with the EQUIPMENT OUT OF SERVICE label (see Appendix B) so it is clear it is not in use.
    3. Equipment Granted Conditional Acceptance Under Work Process E: Prototype or proof-of-concept equipment (e.g., test chassis, benchtop experiment) in the process of being built to test the validity of a design and that is under the exclusive control of the designer if used for less than three months. Equipment being developed that exceeds a three-month period may be acceptable but requires Conditional Acceptance per Work Process E.
    4. Equipment Considered Nonhazardous:Equipment in any of the following categories is considered nonhazardous:

    Note: Equipment that is connected to AC only via a step-down transformer/AC adapter with voltage output less than 50 volts is exempt, but the transformer/AC adapter must be NRTL Listed.

    D. Policy Statement

    The Berkeley Lab Electrical Equipment Safety Program (EESP) is designed to ensure the safe operation and installation of electrical utilization equipment.Only electrical utilization equipment that has been approved by the AHJ may be used at Berkeley Lab. Electrical utilization equipment that has been Accepted, Certified, Labeled, or Listed by an NRTL is considered acceptable to the AHJ, and is approved for use provided the equipment is installed and used within the manufacturer's listing intent. Electrical utilization equipment that has NOT been Accepted, Certified, Labeled, or Listed by an NRTL is not acceptable to the AHJ unless it has satisfactorily passed a documented safety inspection. To meet this requirement, Berkeley Lab has established the EESP.

    Upon installation, and prior to energization, newly purchased or Berkeley Lab–built electrical utilization equipment:

    F. Definitions/Acronyms

    Term Definition

    Approved

    Acceptable to the Authority Having Jurisdiction (AHJ)

    Acceptable

    Electrical utilization equipment is "acceptable" to the Berkeley Lab AHJ and approved if it is accepted, certified, listed, labeled, or otherwise determined to be safe by a Nationally Recognized Testing Laboratory (NRTL).
    If it is not determined to be safe by a Nationally Recognized Testing Laboratory (NRTL), it is acceptable if it is inspected or tested by another federal agency, or by a state, municipal, or other local authority responsible for enforcing occupational safety provisions of the National Electrical Code and found in compliance with the provisions of the National Electrical Code.

    Custom-made equipment or related installations that are designed, fabricated for, and intended for use by a particular customer is acceptable if it is determined to be safe for its intended use by its manufacturer on the basis of test data that the employer keeps and makes available for inspection to the Berkeley Lab AHJ and the AHJ's authorized representatives.

    Accepted

    Electrical utilization equipment is "accepted" if it has been inspected and found by a Nationally Recognized Testing Laboratory (NRTL) to conform to specified plans or to procedures of applicable codes.

    Authority Having Jurisdiction (AHJ)

    Generally, an organization, office, or individual responsible for enforcing the requirements of a code or standard, or for approving equipment, materials, an installation, or a procedure. At Berkeley Lab, the Electrical AHJ function is divided three ways:

    1. The AHJ for Electrical Safety work practices and workplace conditions is the EHS Electrical Safety Program Manager.
    2. The AHJ for research and scientific equipment is the Engineering Division Director.
    3. The AHJ for facilities and premises wiring is the Facilities Division Director.

    Certified

    Electrical utilization equipment is "certified" if it bears a label, tag, or other record of certification that the equipment:

    • Has been tested and found by a Nationally Recognized Testing Laboratory (NRTL) to meet nationally recognized standards or to be safe for use in a specified manner.  
    • Is of a kind whose production is periodically inspected by a Nationally Recognized Testing Laboratory (NRTL) and is accepted by the laboratory as safe for its intended use.

    CE

    Conformité Européene:
    This is a manufacturer's self-declaration of conformity to European design standards. It is not equivalent to an NRTL listing because:

    • There is no third-party verification of conformity through inspection or testing.
    • The standards are not recognized for applicability in the United States.

    Electrical Equipment Safety Program (EESP)

    An inspection program designed to meet the OSHA requirement for AHJ acceptance of Unlisted electrical utilization equipment

    Field evaluation

    An electrical equipment safety inspection on Unlisted equipment performed on site by a Third-Party Field Evaluating Body (FEB)

    Field Evaluating Body (FEB)

    An organization that performs electrical equipment safety inspections and that is recognized by the AHJ. It is recognized by the AHJ if it meets the requirements of NFPA 790 and NFPA 791.

    Inspection

    An equipment electrical safety inspection performed on Unlisted equipment by an authorized EESP inspector

    Legacy equipment

    Electrical utilization equipment surveyed before October 1, 2013

    Labeled

    Electrical utilization equipment is "labeled" if there is attached to it a label, symbol, or other identifying mark of a Nationally Recognized Testing Laboratory (NRTL) that (1) 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 (NRTL Listed)

    Electrical utilization equipment is "Listed" if it is of a kind mentioned in a list that is published by a Nationally Recognized Testing Laboratory (NRTL) that (1) 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.

    Nationally Recognized Testing Laboratory (NRTL)

    An organization that is recognized by OSHA and that tests for safety; or lists, labels, or accepts equipment based on established national standards. The NRTL is an independent third party and is not the manufacturer of the product or a government agency. A partial list of NRTL labels is provided in Appendix A.
    The full list of NRTL labels can be found online at:
    {+}http://osha.gov/dts/otpca/nrtl/nrtlmrk.html+

    Reputable manufacturer

    Manufacturers listed in Appendix D are considered reputable and provide adequate technical support and technical documentation, and follow standard accepted safe designs even though they do not always obtain NRTL listing for their products.

    Survey

    The process of identifying and indexing Unlisted electrical utilization equipment that will later be inspected by a designated EESP Equipment Inspector.

    Surveyor

    Personnel identified by their division to conduct the NRTL survey for their organization are referred to as Electrical Equipment Surveyors. Before conducting the survey, Electrical Equipment Surveyors must complete training course EHS0381.

    Unlisted

    Electrical utilization equipment is "Unlisted" if it is not listed.

    Utilization equipment

    Equipment that utilizes electric energy for electronic, electromechanical, chemical, heating, lighting, or similar purposes

    G. Recordkeeping Requirements

    Electrical utilization equipment surveys, inspections, status, and approvals are maintained on the EESP database.
