Permit-Required Confined Space (PRCS) Identification and Signage



At Jefferson Lab a Confined Space Entry (CSE) Permit is considered to be a Work Control Document and thus a Standard Protecting Measure.  Only when all hazard issues associated with the PRCS and the work activity are acknowledged and mitigated, in accordance with this program, can the area’s associated Risk Code be considered < 2.  At a minimum, all work requiring entry into a PRCS is discussed with the entry supervisor prior to commencement. 


A formal Task Hazard Analysis and Operational Safety Procedure is required for work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process.
