ES&H Manual
Chapter 6200 Electrical Safety Manual
The purpose of this Electrical Safety Manual is to establish minimum requirements for identifying and controlling electrical hazards to prevent fatalities and injuries from working on or around hazardous electrical energy, and to establish Jefferson Lab National Accelerator Facility (Jefferson Lab) site-specific electrical safe work practices that meet regulatory requirements and match the types of hazards found on site.

This document establishes the institutional requirements and electrical safe work practices at Jefferson Lab for both QEWs and non-QEWs. It includes electrical work practices, maintenance requirements, training, and installation requirements for facilities distribution and premises wiring, utility distribution, and commercial and Research and Development (R&D)-type equipment.

These safe work practices are being driven by:
