6220 Appendix T1

Energized Electrical Work Permit (EEWP) - Instructions



1.0             Purpose


In accordance with Occupational Safety and Health Administration (OSHA) 29 CFR 1910.333 and National Fire Protection Association (NFPA) 70E, work on energized equipment is only allowed when de-energizing the equipment either introduces additional or increased hazards; or it is infeasible to perform the work de-energized. This appendix provides requirements for developing an Energized Electrical Work Permit (EEWP) to justify the need to perform this type of work.


2.0             Scope


This document is limited to work on energized equipment as described in NFPA 70E. Work on energized electrical equipment for the purposes of diagnostics is permitted by Jefferson lab without an EEWP provided appropriate safe work practices and PPE are used, in accordance with NFPA 70E Articles 110 and 130.


3.0             Responsibilities


3.1              Anyone at Jefferson Lab:

·         Understand work scope and safety requirements, including personal protective equipment (PPE) requirements.

·         Verify that work can be accomplished safely with known hazards mitigated.

·         Determine that work must be done energized and receive preliminary concurrence from the Lab Director to continue with the EEWP.

·         Prepare and submit EEWP for approval.

·         Follow the approved EEWP as developed.

·         Stop work if it deviates from the EEWP. Return equipment to a safe condition. Revise work plan including changes in safety requirements as necessary. Obtain approvals for any revised work plan.

·         Provide feedback on work completed for lessons learned.


3.2              Supervisors/Subcontracting Officer’s Technical Representative (SOTR):

·         Assign work to qualified personnel.

·         Prepare and review work procedures with qualified person's input.

·         Ensure all necessary safety equipment is adequate and used.

·         Provide work oversight to verify compliance with EEWP.


3.3              ES&H Electrical Safety Engineer:

·         Review EEWP to verify that all requirements have been met before forwarding to Associate Director/Division Manager (of group requesting the EEWP).


3.4              Associate Director/Division Manager (of group requesting the EEWP):

·         Review EEWP to verify that all requirements have been met before forwarding to Laboratory Director.


3.5              Laboratory Director

·         Preliminary review and approval of Part 1 of the EEWP.

·         Final review and approval of completed Part 2 of the EEWP.


4.0             Process Steps


Step 1:            Using the EEWP Form, the individual requesting the work completes Part 1. Upon completion of this section, the requestor obtains preliminary approval from the Laboratory Director. 

Step 2:            The requestor submits the EEWP Form to the Subject Matter Expert (SME) for completion.

Step 3:            SMEs complete Part 2 – Development, which includes advice from qualified persons.

Step 4:            Upon completion of Part 2 Development, the SME distributes the EEWP Form for review and approval.

Step 5:            Final approval is contingent on the Laboratory Director’s signature.
