Safety during Hardware Commissioning

Thursday 18 Oct 2007, 09:00 → 18:00 Europe/Zurich

AT Auditorium (CERN)

Opening session

1. Why this day?
2. Objectives of the day
   • Improve the knowledge on risks
   • Clarify procedures to avoid risks
   • Review the status of documentation
3. Program of the day

slides Safety_Day_-_RSa_2.pdf Safety_Day_-_RSa_2.pptx

Safety for the LHC

1. General safety measures (Access in the LHC tunnel, ODH, Fire detection,…).
2. Special situation with the HC (people in the tunnel during the tests, safety protections removal, equipments not tested, etc…)
3. Risks for the worker and for other people
4. To do something, somewhere, somebody
   Somewhere:
   • Delimited areas
   • Balisage and its meaning
   Somebody:
   • Intervenant
   • EIC
   Something: Different types of works
   • Tests:
   - activities part of HC (ElQA, PIC, DC connection)
   - described in HC procedures
   - safety treated in HC procedures
   • Intervention:
   - No directly part of the HC (e.g. cleaning of the filter)
   - Short time
   - Urgent
   - Procedure vs not procedure
   • Work:
   - Activities no part of the HC (e.g. change of an AC transformer)
   - CERN safety procedures MUST be applied
   - Not done by HC team

Safety during Hardware Commissioning

1. Organization and coordination of the HC period:
   • Roles and responsibilities
   • Possibility of coexistence between activities
2. Special case of powering tests:
   • Co-activity test-test and test-intervention
   • Announcing of the activities
   • Tracking of the activities

Safety during the interventions

1. What is an intervention?
2. General organization of the intervention (Actors, responsibilities, tracking)

Electrical works vs Not electrical works in electrical environment

1. What is an electrical work
2. Who can work on an electrical circuit?
3. Procedures, different actors (Chargé de travaux, Chargé de consignation) and their responsabilities (B0, B1, B2)
4. Consignation vs condemnation
5. Working in proximity of an electrical circuit. What is it?
6. How to manage electrical risk?

Special cases of cryogenic intervention

1. What are the risks generated by cryo?
2. Where are the risks (tunnel/UA)
3. Works on the DFBs, cryomagnet, etc…
4. Works at proximity of the cryo equipments
5. Consignation
