SCE group IC009 SCE group title Flare Tip Ignition Systems Flare Tip Ignition systems to ensure that gas from the flare system does not accumulate and cause a hazard to the Facility, following planned or emergency depressurisation. To ensure that gas from the flare system does not accumulate and cause a hazard to the Facility, following planned or emergency depressurisation. At system level SCE group DS001 SCE group title Fire and Gas Detection Fire and Gas Detection Systems for detection of flammable or toxic gas, or fires. To detect all flammable gas accumulations, oil mist accumulations, the presence of toxic gases (including asphixiants and narcotics) and all fires and initiate an executive action Flammable Gas Detection System comprising: o all types of detectors fitted, which may include Catalytic detectors, Infra-Red Point Detectors, Infra-Red Beam Detectors and Acoustic Leak Detectors o gas in service water detection o HVAC gas detection o flammable gas detection functions on main and any additional Fire and Gas panels and outputs to end elements Manual Alarm Call points (MACs) System comprising: o GPA Call points positioned at various locations around the installation o manual alarm functions on main and any additional Fire and Gas panels and outputs to end elements Oil Mist Detection (OMD) System comprising: o oil mist detector heads, normally located in areas where oil mists present a risk of fire and explosion o oil mist detection alarm functions on main and additional Fire and Gas panels and outputs to end elements HS Detection System comprising: o HS detectors, alarm functions on main and additional Fire and Gas panels o outputs to Facility alarm systems including flashing warning beacons and local sounder devices initiated by HS detection.
