- 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 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
  slides
- 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
  slides
- 10:20
  
  Coffe break
- Safety during the interventions
  1. What is an intervention?
  2. General organization of the intervention (Actors, responsibilities, tracking)
  slides
- 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?
  slides
- 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
  slides
- 12:15

  slides
- General CERN safety
  1. Main CERN hazards (Electrical, Gas, Cryo, Tunnel, etc…)
  2. CERN safety plan (SAPOCO-42 based on international regulations)
  3. The different actors (DSO, TSO, Glimos, etc…)
  4. CERN procedures (Fire permit, AOC, etc…)
