3. DESIGN PHILOSOPHY 3.1 Single Fire/Flammable Liquids or Gas Leak Risk The fire fighting system is planned on the assumption that there will be a single major fire or major leak of flammable liquids at a time in block station and fires simultaneously

will not occur

at different places in the same time at block station (single jeopardize

concept ).

3.2 Self Supporting System The fire fighting system is based on the assumption that the block station always permanently operate by operation persons for 24 hours continue and the fire mitigate by

operation

person who in charge at the time using permanent fire protection equipment which are available in the plant include fire water hydrant, deluge system, foam system, dry chemical, or other fire extinguisher based on the fire sources and location of fire.

Fire man using

fire truck and no external fire f ighting r esources will be supported by request from operation person.

3.3 Fire Fighting Agents The following fire fighting agents shall be considered as the basis of fire fighting system design:

(1) Water Water is applied for extinguishing fire, controlling fire intensity, prevention of fire to cool down equipment exposed to heat radiation by fire. Water should not be applied for controlling f ire intensity at electricity equipment such as Switchgear, MCC, Voltage Regulator, and also

should not be applied into cryogenic

liquid and fires because it will accelerate the vaporization speed. (2) Foam Foam is an aggregate of air-filled bubbles formed from aqueous solutions and is lower in density than flammable liquids. It is used principally

to form a cohesive floating

blanket on flammable and combustible liquids and prevents

or extinguishes fire by

excluding air and cooling the fuel. It also prevents re-ignition by suppressing formation of flammable vapors. It has the property of adhering to surfaces, which provides a degree of exposure protection from adjacent fires. Document No : Revision :


8 of 21


(3) Dry Chemical (portable and wheeled ) A dry chemical extinguishing agent is powdered materials consist of Sodium Bicarbonate or Potassium Bicarbonat. It is noted that there is a possibility of re-flash of flammable material after extinction by dry chemical. NFPA 10 for portable dry chemical extinguishers, NFPA 11 for combined agent systems, and NFPA 17 for fixed dry chemical system shall be used as a minimum guideline. (4) Clean Agent Fire Extinguishing System 2

Clean agent gas is effective to extinguish fires in an enclosed space for electrical installations,

instrument/computer,

sub-floor

or

ceiling

cable

plenums and special

machinery, where water application is not permissible. When applying inert gas into such enclosed

space, the asphyxiation hazard to personnel must

be recognized and

addressed.

5. FIRE WATER SUPPLY SYSTEM Fire water systems should be designed to supply sufficient quantities of water to all areas of a facility.

The facility fire water supply should be capable of providing much of the anticipated

demand with any "impairment" to the system. An impairment could be the loss of a single fire pump, adverse

reduced suction supply, a break in the distr ibution condition.

This means that

piping, a shut valve, or other

looped and redundant

water supplies should

be

provided to minimize any single failure. Firewater should be used for fire fighting purpose only so that a required firewater am ount is reserved all the time. T he quantity of firewater supplied is sufficient to limit heat absorption to adjacent equipment. 5.1 Fire Water Supply There are two critical factors to consider when designing the water supplies. These are adequacy and reliability. Adequacy of the systems is determined by the capability of the supply to meet the flow and system pressure requirements for the anticipated duration which Document No : DNGF-PR-200-DBS-1009 10 of 21 Revision : 2


is 4 hours. The system must also be reliable under adverse conditions such as those following an explosion, so redundancy should be provided. Also, the onsite dedicated fire water stor age should have the capability of replenishment within 4 days. Fresh water from deep well water is used as fire water source. 5.2 Fire Water Demand Fire water demand in each area is determined on the calculation basis on actual fire protection applied at each single fire scenario. The largest firewater demand calculated shall be considered as the "Plant Firewater Demand", as the basis to determine the capacity of the plant firewater supply system and capacity of the fire water pump required. 5.3 Fire Water Distribution System The fire water distribution systems should be sized to limit the friction loss from t he supply to the greatest hazard and to meet the maximum fire water demand including expected fire hose and monitor nozzle requirements. Future plans should be included in any design. NFPA 24, "Standard for the Installation of Private Fire Service Mains and Their Appurtenances" should be consulted for minimum installation requirements. When laying out the fire water distribution system the following should be considered : •

Sizing Fire Water Ring to take advantage of the water supplies available. Large pumping capacities can be wasted if the water distribution system can not deliver the water to the desired areas at effective pressures. A looped or gridded distribution piping is considered to t he design.

•

Providing adequate backflow prevention when public or other potable supplies connect to the system.

2 •

Provide a separate connection to the distribution system for each supply.

•

Burying distribution piping to prevent an explosion within the faclity from impairing the system.

•

Providing adequate valving to isolate damaged section of the systems. Fire Water Ring should have indicating-type sectional valves located at appropriate locations on the grid. The sectional valves should be installed at other apropriate points in order to minimize the extent of impairments. hydrants,

monitors,

The isolating valves should be placed so that

deluge & spray systems,

sprinkler

systems

or

other

fire

protection systems could still operate by isolating the problem using the valves. Sectional valves should be arranged so that no more than five pieces of equipment

(hydrant, deluge valve, monitor, etc.) will be impaired at any one time. Document No : Revision :


11 of 21


5.3.1 Fire Water Piping System The firewater piping system is under ground, buried at 0.9 m depth, except ground in tank area, under the building or foundation of equipment. Buried section is protected by epoxy

tape wrapping and impressed current is used above. The firewater system

should be tested and flushed on weekly basis. Lines is sized to provide the maximum required fire water flow to fire area with an acceptable residual pressure not less than 100 psig. The velocity of the fire water in the piping system should not exceed 4.8 m/s (16ft/sec.) No underground line is smaller than 6 inch. The type of fire water pipe shall be in accordance with NPFA 24 and the applicable

project pipe specifications. For the fire water system, the pipes use material carbon steel with 150 #RF of rating.

5.3.2 Block Valve For every 5 units of equipments (hydrant, m onitor or water sprinkle) or for every 243 meter distance, 1 block valve is installed . The block valve is the Gate valve type. The Block valve is installed at the control basin and easily operated from above ground. 5.3.3 Fire Water Storage Fire water storage is provided in accordance with NFPA 22. Fire water is stored in a fire water pond. The quantity of fire water stored is calculated by multiplying the maximum fire water demand by four days. The quantity of fire water required is dedicated to the fire water system. No other use of the fire water is allowed. The pond have provisions for the refilling of the fire water tank in a timely manner.

5.3.4 Fire

Water

Pump System
