6160 Appendix T1

Listing of Permit-Required Confined Space (PRCS) Locations

 

 

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.

 

1.0          Purpose

 

This appendix provides a listing of Jefferson Lab’s currently known Permit-Required Confined Spaces (PRCSs).  They are generally located underground and entered through manholes.  Entry is infrequent and normally made by a Jefferson Lab authorized subcontractor.  

 

2.0          Scope

 

This appendix is reviewed annually however, it does not guarantee that all PRCSs are listed.  Contact the Confined Space Coordinator if you have questions, concerns, or to request a hazard evaluation of an area.   

 

Jefferson Lab defines a “PRCS” to be any area that meets all of the following criteria:

 

·       Sufficient space for a person to enter and perform work;

·       Limited/restricted means for entering/exiting;

·       Not designed for continuous occupancy.

 

AND one or more of the following criteria:

 

·       Contains, or has the potential to contain, a hazardous atmosphere;

·       Contains a material with the potential for engulfing a person or hindering quick escape;

·       Internal configuration can trap a person or lead to asphyxiation;

·       Entails a safety or health risk that has been determined to be >2 and requires a formal Task Hazard Analysis and associated work control document. 

 

The process steps for this procedure are performed in coordination with ES&H Manual Chapter 6160 Permit-Required Confined Space Entry Program.

 

3.0          Responsibilities

NOTE:           Management authority may be delegated at the discretion of the responsible manager.

 

3.1            Entry Supervisor/Subcontracting Officer’s Technical Representative (SOTR)/ Sponsor

·       Know the PRCSs under your authority.  Ensure they are appropriately identified and secured.

 

3.2            Confined Space Coordinator

·       Maintain the listing of PRCSs.
