6200 Electrical Safety Program



1.0             Purpose

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

2.0             Scope

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

Jefferson Lab allows only trained personnel to perform electrical work. General safety training requirements are determined by the task assigned and are outlined in Table 1 below. In addition to the training listed below, the employee will have demonstrated proficiency in a work practice before being deemed qualified to perform the task. A qualified person shall be trained and knowledgeable in the construction and operation of equipment or a specific work method and trained to identify and avoid the electrical hazards that might be present with respect to that equipment or work method.

4.0             Appendices


4.1              Electrical Safety Inspection Procedure

Electrical equipment meeting the criteria stated within the scope of ES&H Manual Chapter 6200 Appendix T1 Electrical Equipment Safety Inspection Procedure, require a safety inspection prior to use. This procedure provides Jefferson Lab’s minimum requirements for a qualifying electrical safety inspection and complies with the requirements of Occupational Safety and Health Administration (OSHA) 29CFR1910.399 Electrical. 


4.2              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.


4.3              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. Some of the practices include power cords, ground-fault circuit interrupter (GFCI), wall/blind penetration, abandoned cable management practices, 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. 


4.4              [NOTE: 6200 T4 IS DELETED]

4.5              Electrical Code Equivalency Determinations

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 provides the process steps for initiating a request, reviewing a request, and approving the request to ensure an adequate level of safety.


4.6              Electrical Authority Having Jurisdiction
