EHN 1 CO2 Leaks inside the beam lines D.Jaillet EN-EA-CT

CO2 Leak in H8 (PPE148) Middle June leak of CO2 inside H8 (PPE148) CO2 gas pipe disconnected to the XCET 042.519 CO2 manual valve open (Leak flow estimated: ~ 12m3/h) A2 and EDMS 1817641 v.1(Incident report) PPE 148 :XCET PPE 158 :Panneaux CO2 EDMS : 1810223 v.1

Proposal:ODH-CO2 Hazard in beam lines ODH Risk assessment(Should be performed): PPE 148 PPE 132 PPE 124 PPE 152 Mitigation measures: Portable/fix detector + Signage of the PPE(Risk of oxygen deficiency-Risk of high CO2 concentration) Flow monitoring Locking the valves (Request to be open) EDMS : 1810223 v.1

Reminder/Recommendation Personal protective equipment Follow the safety rules Do not touch if you don't know HSE will send a SAFETY BULLETIN about the compression fitting connector  Check them If you need help(Gas for experimental area ) Contact gaz.service@cern.ch EDMS : 1810223 v.1
