-
EXSO (GLIMOS) refers to

C-2-0-2 and
and advice from FGSO
and HSE unit (Flammable gas safety).
- Complete ISIEC Form at ISIEC Form on EP Safety site
- Based on advice from FGSO and HSE unit (Flammable gas safety) and at an early stage:
- If gas detection needs to be installed - contact Nicolas Broca GS/ASE for quote, installation, etc. All new gas detection installations must pass an Acceptance test, organized by GS/ASE, report issued by HSE Unit;
- Procedures and flow diagram to be drawn up by EXSO (GLIMOS).
-
Prior to the operation with flammable gas:

- FGSO Completes Form C-2-0-2, Hazardous area classification (ATEX Zone) - Carried out by FGSO - in cooperation with HSE Unit (Flammable gas safety);
- EXSO (GLIMOS) organizes check specification of electrical equipment in the Hazardous area (ATEX Zone). Contact HSE Unit, Electrical safety;
- Declaration of a Flammable Gas Zone (C-2-0-3 Form)
EXSO (GLIMOS) completes with copies to relevant people as on form (Nicolas.Michel.Broca@cern.ch (GS/ASE), Fire.Brigade@cern.ch (GS/FB), David.Jaillet@cern.ch (EN/MEF), Jonathan.Gulley@cern.ch (HSE Unit))

- Cancellation of a flammable Gas Zone (C-2-0-3 Form)
EXSO (GLIMOS) completes with copies to relevant people
