  2. Project Goals • Install in LHC • Fire Detection • Flammable Gas Detection • Oxygen Deficiency Detection • Evacuation Systems • In accordance to User Requirements

  3. User Requirements • TIS • Requests Detection for the PROTECTION OF PEOPLE • Owners of Buildings • Request Detection for the PROTECTION OF EQUIPMENT

  4. Surface Sites • CERN Sites Divided into Safety Zones

  5. LHC Surface Sites Strategy • CERN Sites Divided into Safety Zones • 1 Fire Panel / Zone • 1 Gas Panel / Zone PA1 ATLAS

  6. LHC Surface Sites

  12. LHC Point 5 - CMS

  13. LHC Point 6

  14. LHC Point 7

  15. LHC Point 8 - LHCb

  16. What happened to the old equipment? • Removal/renewal of all detection equipment • Adapt to new use of installations • Reduce maintenance costs  • Replace with less and better • Remove obsolete/useless • Improve performance • Reduce spurious alarms  • To achieve this, we need • Input from users (TIS, ST, Experim, etc)

  17. LHC Underground

  18. Experiments • Experimental Apparatus • Need for specific devices • Experimental Cavern • Need for generalized detection • Service Caverns • Need for generalized detection • Need for specific devices (e.g. racks)

  19. LHC Experiments - ATLAS

  20. ATLAS Experiment • Detect Smoke, Flammable Gas and Oxygen Deficiency inside the Detector • FAGIA WG (Fire And Gas Inside Atlas) • Collaboration between • ATLAS Safety (G. Benincasa, M. Hatch) • ST/AA/AS (R. Nunes) • EST/LEA (J. Nebout) • TIS (C. Nuttall, J. Elorza)

  21. LHC Experiments - ATLAS • Preliminary Proposal from ATLAS • 332 tubes • 178 smoke detectors • 122 gas detectors

  22. LHC Experiments - ATLAS

  23. ATLAS Service Cavern • Smoke Detection • Cavern Environment • Specific Racks • Gas/O2 Detection

  24. CMS Experiment • Specific Detection inside the Detector • Generalised Detection for Caverns • Collaboration between • CMS GLIMOS (R. Schmidt) • CMS DCS (W. Funk) • L3 GLIMOS (J. Pothier) • ST/AA/AS (R. Nunes) • TIS (F. Szoncso)

  25. LHC Experiments - CMS

  26. LHC Experiments - CMS

  27. LHC Machine • Fire Detection • Agreed in specific locations • UJ: 14,16,33,56 • UA: 23,27,43,47,63,67,83,87 • RR: 13,17,53,57,73,77 • RE: all (12,18,22,28,32,38,42,48,52,58,62,68,72,78,82,88) • Differing opinions from TIS and LHC for tunnel • Gas Detection • Awaiting decision for generalized O2 deficiency detection from LHC
