- 9. FGDS Component • The F&G Detection System incorporate four main systems: Fire Detection And Alarm Systems. Gas Detection And Alarm Systems. Low Temperature Spill System. Emergency Warning System.
- 10. Fire&Gas Detection And Alarm System • F&G detection devices distributed in all buildings and allover the plant. The Buildings : Smoke Detectors, Heat Detectors ,Gas Detectors and Manual call points. The Plant : UV&IR Flame Detectors, Open Path Gas Detectors, Point Gas Detectors, Combustible Gas Detectors , Leak Detectors and Manual call points.
- 11. Building Fire Detection And Alarm System • Buildings designed with due considerations for the requirements of NFPA 101, “Life Safety Code”. • All buildings provided with low flame spread interior finish , non-combustible furnishings and safety features in accordance with NFPA 101. taking into account API RP 752 “Management of Hazards Associated with Location of Process Plant Buildings” provisions.
- 12. • Each building has its own fire detection & alarm system, and fire and gas alarm panel for annunciation of alarms by the building smoke, gas and/or heat detectors.
- 13. Smoke Detectors • Two types of smoke detectors used: A- Ionized Gases Detectors (Invisible Products Of Combustion).
- 14. • B- Visible-Products – Of – Composition
- 15. Heat Detectors • These devices sense over heating inside certain rooms in the building.
- 16. Gas Detectors • These detectors located in the entrance dumber of HVAC and Lab. Room.
- 17. The Plant Fire&Gas Detection And Alarm System • The Fire Alarm and Gas Detection Systems are independent and fully segregated from other systems. The F&G system contain interfaces with the Process DCS system for alarm display. The F&G system also perform in conjunction with the Fire Suppression System and the various Building Fire Detection Systems. • Automatic fire and gas detection devices installed at strategic locations in the plant to monitor hazardous conditions and events. In addition, manual call points strategically located throughout the plant .
- 18. UV/IR Flame Detectors • FL 3100 flame detector monitors in both UV&IR spectral range reducing possibility of false alarms caused by lightening ,arc welding and hot objects. • Typical response time < 3sec. @50ft • 120O maximum horizontal field of view. • -40 o c to +85 o c operating temperature. • COPM ( Continuous Optical Path Monitoring), the optical path is self checked once every minute on both the UV&IR sides to make sure the windows are not dirty, and that the test sources and detectors are working properly.

- 21. Open Path Gas Detectors • IR 5000 is an open path gas detectors using a single IR beam technology and has an auto zero and auto track alignment . • Measurement depends on the length and the size of the gas cloud. concentration x Length = measurement This detector is a dual range one: 0-5 LEL*meter and 0-5000ppm*meter • Detect very small leaks with 0-5000ppm range before they become major problems.
- 22. • The 0-5LEL*meter range alerts that there is a major leak somewhere between the source and detector

- 27. Leak Gas Detector (low temp. spill detector) • These detectors detect spillage of cryogenic liquid by detecting decreasing in surrounded temperature.
- 28. Heat Detectors • When tank pressure getting high and over PSV’S set point the PSV’s open to atmosphere, LNG Vapor Released and may fire happened due to Electrical Static charge on the PSV’s Stacks. Heat detector which placed on the PSV’s Stacks Send Signal to the Solenoid on the Nitrogen Cylinder to initiate the Dry Chemical Powder System to Extinguishing the Fire.
- 39. Emergency warning and evacuation system • A plant-wide alarm annunciation system for separate and distinctive alarming of fire, and accidental release/spill incidents. The plant- wide alarm system consists of interchangeable alarm tone generating devices and field-mounted horns suitable for the classified areas. • Process area strobe lights suitable for classified areas provided in high noise areas for alarming purposes. • The standard alarm devices for building interiors of non-hazardous occupancies is a combination of horn/strobe light.
- 40. • Manual call points MAC's located along the periphery roads around process train and utility area, and LNG storage area with a travel distance of maximum 60 m. At LNG loading jetty, MAC’s shall also be located on the trestle at a maximum distance of 60 m from the jetty head and at a strategic points on the jetty head (if applicable).
- 41. • MAC’s are pull handle type and suitable for installation in hazardous area when installed outside of building.
- 42. Emergency Response • In case of any emergency situation, the emergency alarm will be activated. • Head to the nearest muster point In the Upwind direction. •Report your self to the muster point checker • Wait for further instructions.
- 45. Wind socks • Wind socks distributed all over the site in high and visible locations • Wind socks are very useful especially in emergency situation. During evacuation all persons should observe wind socks to head to the safest muster point. (upwind) • Emergency response team using wind socks for expecting gas leak and fire spread direction.
