Contact the EHS Electrical Safety Group via email electricalsafety@lbl.gov or stop by and see us in Building 78. We are located behind Facilities (Building 76).

The Laboratory Electrical Safety Officers are responsible for managing the Electrical Safety Program and the Electrical Safety Group and also serve as Electrical Safety Officers for Divisions without an assigned ESO. Division Electrical Safety Officers are responsible for implementing the requirements of the Electrical Safety Program and act as a resource to employees, managers, and Division Safety Coordinators for electrical safety-related concerns. Division Electrical Safety Advocates coordinate with the Electrical Safety Group to resolve concerns and are familiar with electrical safety resources.
