Electrical Equipment Inspector
            Training
           EEI Program at BNL

    Program Goal

    The goal of the Electrical Equipment Inspection
    Program is the review and approval of electrical
    equipment and installations to ensure that
    approved equipment is free from reasonably
    foreseeable risk due to electrical hazards

            EEI Program at BNL
    Evolution

    The Deputy Director of Operations charged the
    Laboratory Electrical Safety Committee (LESC) to
    review the report of the Brookhaven Site Office
    (BHSO) Surveillance Review of Electrical
    Equipment Acceptance, dated July 22, 2004, and
    develop an action plan for addressing the finding,
    concern and two of the three recommendations
    noted in the report

    Evolution (cont)

    The Procurement and Property Management
    Division addressed one of the recommendations to
    assure that BNL complies with the OSHA
    requirements listed in 29 CFR 1910.303 that all
    electrical equipment be suitable for installation and
    use, usually associated with listing or labeling by a
    Nationally-Recognized Testing Laboratory
    (NRTL)

             EEI Program at BNL
    Evolution (cont)


    Participants in a 2004 Occupational Safety and
    Health Administration (OSHA) site-wide review
    noted that equipment was being used despite their
    not being listed or labeled by an NRTL. This was
    also identified as a finding in the Brookhaven Site
    Office (BHSO) Surveillance Review of Electrical
    Equipment Acceptance

             EEI Program at BNL
    Evolution (cont)


    This revealed the need for BNL to implement a
    more formal and rigorous process for electrical
    equipment review and acceptance -----
              And the EEI program was born

             EEI Program at BNL
     Implementation
• The Corrective Action Plan for BNL’s Electrical
  Equipment Acceptance Program dated December
  28, 2004 by the LESC outlines the EEI Program at
  the Laboratory level
• Review and Approval of Electrical Equipment and
  Installations in the Electrical Safety Subject Area
  describes the implementation of the program at the
  Laboratory level
 7
             EEI Program at BNL
    Implementation

• For the NSLS, EDP #000171 describes the
  implementation of the program at the NSLS
• Just to get an idea
     –   Over 20,000 pieces at NSLS
     –   Over 25,000 pieces at C-AD
     –   Unknown quantity in Plant Engineering
     –   Over 16,000 in Balance of Plant

     EEI qualifications

• EEI’s are comprised from a cross-section of
  the Laboratory
• The qualification for EEI’s is a minimum of
  ten years combined schooling/experience
  with electrical/electronic system design
  and/or electrical system construction/

10
              EEI Program at BNL
     EEI Responsibilities

1) Help with the generation of equipment lists by
   aiding in the identification of equipment to be
   inspected
2) Coordinate with equipment owners, inspect
   equipment*, apply bar codes and labels as
   specified by the Electrical Safety Subject Area
   and complete an inspection form

      * An EEI should not inspect equipment they fabricate.

11
           EEI Program at BNL
 EEI Responsibilities (cont)

 3) Enter or submit the completed documentation
    for recording
 4) Direct Users to the Electrical Safety Subject
    Area, especially the Review and Approval of
    Electrical Equipment and Installations Exhibit,
    to minimize the effort needed to modify user
    equipment when it is brought onto the BNL
    site
12
              EEI Program at BNL
     Minimum inspection components*
     1) Equipment sufficiently enclosed to prevent
        accidental contact with energized parts
     2) Exposed metal parts bonded and grounded
     3) Over-current protection appropriate for
        intended use
     * Inspector uses professional experience to add other
       components when deemed necessary
