Why?

Confined spaces are work locations that meet regulatory definitions and require rigorous additional analysis and Work Authorization in addition to the usual safe work practices and procedures required by Integrated Safety Management Systems. Improper entry into confined spaces may result in

What you need to do before performing work:

  1. Define the work.
    1. Review the LBNL Confined Space Inventory to determine if the space in which the work will be performed has been evaluated for classification as a Permit-required Confined Space. See Work Process A.
    2. Inspect the area in which the work will be performed to determine if the area should be classified as a Permit-required Confined Space, and if so contact the Confined Space Program Manager to perform and document the classification. See Work Process B.
    3. Determine if the work requires entry into a Permit-required Confined Space. If so, a specially trained and designated Entry Supervisor must be engaged to perform further analysis of hazards and help develop controls. See Work Process D.
    4. If the work involves a subcontractor entering a potential or actual Permit-required Confined Space, notify the subcontractor and submit the subcontractor’s Permit-required Confined Space Program to the LBNL Confined Space Program Manager for review and evaluation. See Work Process E.
  1. Analyze hazards.
    1. Determine if the work will introduce hazards into the space that must be controlled in order to safely perform work.
    2. Determine if hazards in Permit-required Confined Spaces can be eliminated prior to entry or if continuous forced air ventilation is sufficient to maintain the Permit-required Confined Space safe for entry. Only a designated Confined Space Entry Supervisor may make this determination. See Work Process D and Work Process E, and use Appendix C or Appendix D (as appropriate) for documentation. If the hazards cannot be eliminated or controlled, then the space may NOT be entered by an LBNL employee or guest. The Activity Lead for that project must engage a specialty subcontractor to do the permit entry.
  1. Develop Controls
    1. Work in any space that has been evaluated and included in the LBNL Confined Space Inventory must be conducted at a minimum in conformance with the Safe Work Procedure(s) developed for work in that space. See Work Process C.
    2. If the space has been classified as a Permit-required Confined Space, then hazards must be eliminated or controlled prior to entry into that space. See Work Process D and Work Process E, and use Appendix C or Appendix D (as appropriate) for documentation. If the hazards cannot be eliminated or controlled, then the space may NOT be entered by an LBNL employee or guest. The Activity Lead for that project must engage a specialty subcontractor to do the permit entry.
