5.1.1 The fire water system shall provide water for fire fighting and fire protection for the

process units, utility area, tankage area, buildings, other off-site areas, etc...

Water shall be available for mechanical Foam systems and also, for the cooling of

equipment and structures near a fire. Water for fire fighting shall be provided by an

independent fire ring main fed by the fire pumps and normally cross connected to

the Refinery cooling water system. The fire water pumps shall have suction lineaccess to the raw water line and raw water tanks for emergency purposes and shall

be located at least 30 m from fire water tanks. Provision should be made for

pumping from storage tanks or other reliable sources. Adequate supply of water

must be made available in accordance with National Fire Code, and company,

requirements and approval.

The fire water system shall be sized adequately and designed for fighting two major

fires simultaneously occurring in the refinery and/or tankage area (the most cases of

two major fires in the refinery, or one major fire in the refinery and one major fire in

the tankage area).

Note that each process unit, a tank bounded area or a LPG scheme is considered as a

single hazard. Sizing of main fire water-distribution line shall be based an all linesbeing in service. Basically, the flow velocity in the piping system shall not exceed

1.83 m/sec at 10.35 barg discharge pressure of fire water pumps (for design

purpose).

The system design shall conform to NFPA code No. 24, using a Hazen-Williams

coefficient of 100 for carbon steel pipe and Hardy Cross formula.

5.1.2 Water shall be applied by means of hose and branch pipes using jet, spray or fog

nozzles, or by fixed or portable monitors preferably with interchangeable nozzles

for water or foam jets.

5.1.3 The installed main pumping capacity shall be based on the total consumption in any

one process area (defined as an area in which the fire can be confined without

significant danger of the fire spreading to an adjacent area) of 818 m3/h at 10.35

barg simultaneously with the required flow rate at 10.35 barg to any group of tanks.

The required flow rate to be supplied to the tankage area shall be min. 818 m3/h and

shall be determined on the basis of the total consumption as needed for cooling of

the adjacent tanks next to the tank under fire with inclusion of sprinkler waters.

Each main pump shall have a pumping capacity of 818 m3/h. Standby pumps diesel

driven with total capacity same as the main pumps shall also be supplied. All pump

drivers shall have totally independent power supply.

Driver of main and standby pump shall be sized at 110% of the maximum powerabsorbed by pumps at full load to avoid overloading if there is a pressure drop in the

system at full capacity.

A building of adequate size shall be provided to house fire water pumps. Adequite

space for maintenance and suitable overhead crane with adequate capacity for

heaviest load shall be provided.

The motor driven main pumps shall come into service automatically and diesel

driven pumps shall have on and off switches at the fire station and power station

room (utility board).The jockey pumps shall maintain the pressure in the fire water

line system to 10.35 barg, automatically. If a jockey pump is used in refinery, it

shall be "spared" and both pumps shall have a capacity of 113m3/h (500 gal/min) to

compensate for leakages. (For pump station the capacity of jockey pump shall be15m3/h)

5.1.4 For design purposes the flow velocity in the piping system shall not exceed

1.83m/s@ 10.35 barg. Fire hydrants shall be maximum 45 meters apart in process

and utility area and maximum 60 meters apart in the off-site area, but their location

generally will be determined in relation to the plant to be protected; all hydrants

must be easily accessible.

5.1.5 Fire hose reels shall be located in each process unit and utility (Boiler area)

normally 30-45m apart at certain strategic points. In general, hose reels are not

required for protection of elevated platform or fin fans containing hydrocarbons.

These areas will be protected by fixed water monitors. Outdoor hose reels shall be

mounted on a frame to facilitate waist level operation.

5.1.6 In locations, such as LPG Storage and bullets, hydrogen plants, etc., where very

large quantities of water in jet or fog forms are required, fixed monitors,

permanently secured to monitor hydrants shall be installed. All fixed water monitors

shall be placed at ground level in order to enable easy operation and so as to provide

effective cooling. All fixed water monitors shall be carefully placed to avoid

unnecessary obstructions like pipe lines and support columns. However, monitors

shall be at least 15m away from equipment to be protected. Use of portable water

monitors is recommended in combination with fixed water monitors. Clear access

must be provided for all fixed water monitors. The fire water system shall be

pressurized and maintained at a pressure of 10.35 barg by jockey pump.

5.1.7 Fixed water fog systems may be employed, extinguishing, cooling or restricting a

fire in areas of high fire risk where immediate action is necessary.
