Contact persons for the individual gas systems

• mail to: list of all contact persons

Detector Gases

• list of detector gases

• collection of properties of the gases

• instruction for shift crew: check of pressure in service pipe

• periodic safety inspections of overpressure valves
  (to by carried out every 2 years)
• gas bottles currently used by COMPASS groups

Flammable Gas Detection System / Safety

• safety interim report, MS word

• Summary of Ventilation Meeting on 6-Feb-2001

• Minutes of flammable gas safety meeting 7-Mar-2001

• Minutes of second flammable gas safety meeting 21-Mar-2001
  List of contributions:
  • List of alarm actions ("NA58 user requirement document") by David Hay: MS Word, PDF, HTML
  • List of recommendations from FGSO by Martyn Davenport
  • RICH flammable Gas Safety from Silvia Dalla Torre

2) usage of flammable gas in detectors and gas systems

• IMPORTANT: inform the GLIMOS (Gerhard Mallot Tel.:163425 or 76423) and/or his deputy well in advance (at least one week!) if you want to use flammable gas !!!
• ISIEC form: (Initial Safety Information on Experiemnts at CERN) to be filled in the first time a detector (any detector!) is used at CERN and to be send to the DSO (Divisional Safety Oficer:  Peter Schilly) of the PPE division
• F1 form: risk classification of installations (to be done only once for every installation / detector & gas system, before initial operation ) by FGSO, TIS representative, TSO, GLIMOS or representative (see F3 distribution list)
• F2 inspection (form is provided by FGSO normally) of installation before comissioning by FGSO, TIS representative, TSO, GLIMOS or representative
  • IMPORTANT: list of requirements for F2 inspection !
• distribution of F3 form (new version) - to be completed for declaration (BEFORE switching on the flammable gas) and cancellation of  installations
  • actual F3 distribution list (December 2002)
  • F3 distribution list adress sticker (WinWord)
