  7. Cold smoke extraction Actions Detection Fire men All the air handling units of the concerned area are automatically stopped (Ts/cv) Smoke extraction mode activated by fire men (fire men cubicle) During extraction mode extraction filters will be by-passed End of fire men action No action with RP Air handling units in normal mode restarted by TS-CV Material design 400°C/2h Bernard Pirollet TS-CV-EPA

  9. Pressurization areas 3 separate & independent areas: • Experimental caverns (-) (UX pts 1/2/8 & UXC55 pt5) • Protected areas- technical caverns (+) (USA 15 pt1,UX 85 pt8 & USC55 pt5) • Safe area (++) (PM/PZ) M M M D N V S L E L E M M M D N V S L E L E M M M D N V S L E L E (-) UXC55 Differential pressure (+) PX56 (+ +) Racks Services Bernard Pirollet TS-CV-EPA USC55 PM54
