Electrical Safety at NSLS-II

If you are bringing electrical equipment to NSLS-II for your experiment, it is essential that this equipment is inspected prior to use. In addition to the inspection, all electrical equipment is required to bear the marking of a Nationally Recognized Testing Laboratory (NRTL). Examples of NRTLs include Underwriters Laboratories, Inc. (UL) or the Canadian Standards Association (CSA). To view the entire list of acceptable NRTLs, visit U.S. Department of Labor Occupational Safety and Health Administration website.

Please note that the generic CE mark is a European self-certification applied to a product by a manufacturer or vendor who declares that their product complies with European standards. The CE mark does not represent a third-party product evaluation and is not comparable with the NRTL listing. You can help speed the process of on-site inspection by sending the make, model number(s), and specifications for your equipment to Jerome Malley (malley@bnl.gov). Then, you should inspect the equipment for the following before your visit to BNL:

1. Grounded chassis
2. 3-wire plugs or double-insulated enclosures
3. Fused inputs
4. No gaps/holes large enough to access live parts

Your electrical equipment that is not NRTL marked will need a more thorough inspection by Electrical Equipment Inspectors upon arrival at NSLS-II. Please note that any electrical equipment set up before inspection must remain unplugged.

For more information about electrical inspection, please read the Electrical Equipment Inspection (EEI) Criteria Guide (pdf).

When you are ready to request an inspection, or need additional information, email an Electrical Equipment Inspector (EEI) with the following information in the body of your email message:

1. Requestor Name
2. Telephone #
3. Email Address
4. Number of Pieces to Inspect
5. Department (NSLS-II)
6. Comments

Note that all equipment being brought to NSLS-II must also be listed on your SAF.
