Operate Fire and Gas Detection System

2. Fire And Gas
Detection System
(FGDS)

3. Presentation Objective
And Contents
• This presentation is implemented to provide the necessary
general information for ELNG fire and gas detection system.
• It highlight &clarify the following points:
 purpose of the FGDS system.
 layout and description of all system devices.
 operational perimeters.

4. Purpose Of the FGD System
• The overall goal of “Fire and Gas Detection System” is to
warn against the presence of flammable liquid spills, flammable
or toxic gas releases, and/or fires in Buildings or in the plant.
This detection will accomplish the following:
 Provide warning to personnel at the Control Building, Fire Station and locally
as deemed necessary.
 Provide a specific hazard location for operations and emergency response
personnel.
 Provide a possible indication as to the extent of the problems.

5. Monitoring
• FGDS System is monitored by:
 Fire and Gas Control Panel “Notifier
Panel" which located in: Main control room,
Fire Station, Compressor Substations,
Storage/Loading Substation Propane
Substations, Main Switchgear Building, and
Marine Terminal Building.

6.  Building Fire and Gas Panel local inputs located in
administration building, CCC building, warehouse
,maintenance building, marine terminal building
“MTB”, plant buildings, fire station and main control
room ”MCR”.

7.  Human Monitoring Interface ”HMI” located in Main Control Room
“MCR” and in Fire Station .

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

23. IR Open Path Gas Detector Alarm
Indications on HMI

24. IR Point Gas Detectors
• IR2100 is an IR point gas detector which several dozen
gases and vapors can be detected.
• 0-100LEL
• Whenever anything fails the IR2100 will go into the fault
mode.

25. Combustible gas detector
• IR000S is a Combustible gas
detector , hydrocarbon gas
highly reliable, self-contained,
microprocessor-controlled
monitor with integral 3 digit
readout. It is designed to
measure and display
concentrations of combustible
gases in the range 0-100%
LEL, but will continue to
display concentrations up to
120% LEL.

26. IR Point Gas Detectors and
Combustible gas detector Alarm
Indications on HMI

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.

29. Detectors location

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.

44. Emergency muster points

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.
