ADNOC Classification: Internal. What is gas? The name gas comes from the word 'chaos'. Gas is a swarm of molecules moving randomly and chaotically, constantly colliding with each other and anything else around it. Gases can fill any available volume and due to the very high speed at which they move will mix rapidly into any atmosphere in which they are released. VAPOUR -A gaseous form of a substance that is liquid or solid at varying temperatures and pressures. FUME - airborne dispersion consisting of minute particles that come from heating a solid (often an oxide resulting from a chemical reaction between the particles and oxygen.

ADNOC Classification: Internal. Offshore Oil ar@Gas installations are protected through fixed fire protections stem. Active Fire protection ction in order to put out a fire. Fixed fire prote •on ystem uses gases like Inergen (clean), C02 (in ), logen (inert) to extinguish fire in an enclosure which can be a technical building o ccommodation for offshore crew. Process area in and Oil and Gas facility is also protected through Deluge System which is a pressurized sea water network spreaded across large scale process equipment's in hazardous or safe areas. Active firåprotection also employs handheld fire extinguishers consisting of compressed dry poWer•wptå. Åc 8 fire ptotection is activated through' plant Fire ånd Gas system.
