Chapter 6200 Electrical Safety Program
Jefferson Lab’s Electrical Safety Program provides guidance for implementing safe electrical work practices and maintaining an electrically safe workplace.

This electrical safety program describes the minimum requirements for a qualifying electrical safety inspection, electrical personal protective equipment, general electrical safety, and electrical hazard labeling used at Jefferson Lab, the electrical code equivalency procedure, and the electrical authority having jurisdiction process..

Jefferson Lab allows only trained personnel to perform electrical work. Training requirements are determined by the task assigned and are outlined in Table 1 below.

(a) Required if work involves the control of a hazardous energy.
(b) Required if work involves Mode 2 or Mode 3 work with Class 2 or Class 3 equipment (See ES&H manual chapter 6230T1 for "Determining Equipment Class and Modes").
(c) Seven years of accumulative training, education, or experience relevant to the electrical equipment design and installation standards for the type of equipment being evaluated.

NOTE: Work performed on AC electrical equipment is covered in ES&H Manual Chapter 6220 AC Electrical Equipment Safe Work Policy.

Work performed on AC utilization equipment is covered in ES&H Manual Chapter 6230 Electronic Equipment Safe Work Policy.

Construction and modifications of all electronic equipment is covered in ES&H Manual Chapter 6240 Electronic Equipment - Construction and Modification Safety.


T1 Electrical Safety Inspection Procedure
Non-listed electrical equipment is inspected prior to use and/or installation. The process steps and checklist used to perform electrical safety inspections are found in ES&H Manual Chapter 6200 Appendix T1 Electrical Safety Inspection Procedure and Electrical Equipment Safety Inspection Form.
T2 Electrical Personal Protective Equipment (PPE) Selection Procedure
Electrical PPE is required for work that exposes individuals to electrical hazards such as shocks and arc flash. There are different levels of electrical PPE available. ES&H Manual Chapter 6200 Appendix T2 Electrical Personal Protective Equipment provides guidance for selecting the appropriate electrical PPE for the work being performed.
T3 General Electrical Safety
ES&H Manual Chapter 6200 Appendix T3 General Electrical Safety provides an overview of general electrical safe work practices to be used by everyone at Jefferson Lab. These practices include: power cords; ground-fault circuit interrupter (GFCI); wall/blind penetration; portable and vehicle-mounted generators; and portable and vehicle-mounted engine-driven welding machines. It is recognized that increased awareness of these practices helps maintain an electrically safe work environment.
T4 Electrical Hazard Labeling
Jefferson Lab recognizes that switchboards, panelboards, industrial control panels, and motor control centers may require examination, adjustment, servicing, or maintenance while energized. To ensure the safety of qualified workers authorized to perform such activities, these items are labeled to warn of their potential shock and electric arc flash hazards. ES&H Manual Chapter 6200 Appendix T4 Electrical Hazard Labeling provides the process steps for identifying equipment which needs labeling; how to update, repair, and/or maintain equipment labeling; and gives examples two common labels used at Jefferson Lab.
T5 Electrical Code Equivalency Procedure
When compliance with electrical codes or standards cannot be satisfied Jefferson Lab allows alternative mitigation to be considered (as long as it provides the same or greater level of protection). ES&H Manual Chapter 6200 Appendix T5 Electrical Code Equivalency Procedure and Electrical Code Equivalency Form provides the process steps for initiating a request, and its review and approval, to ensure an adequate level of safety.
   Electrical Code Equivalency Form
T6 Electrical Authority Having Jurisdiction
ES&H Manual Chapter 6200 Appendix T6 Electrical Authority Having Jurisdiction (EAHJ) outlines the responsibilities of the Electrical Authority Having Jurisdiction (EAHJ) position at Jefferson Lab.


Management authority may be delegated at the discretion of the responsible manager.
