B Hydrant System

1 The plant is already provided with overground/ underground hydrant piping network. However, at many locations, the pipes and valves are corroded and damaged leading to water leakage. In view of the above, it is envisaged in this package that entire hydrant piping network shall be re-laid with provision of new overground piping in place of existing underground piping. The pipe route shall be kept same as far as possible. Wherever over-ground pipe routing is not possible, pipes in trenches (especially around Main power house building) or under ground piping (with proper coating and wrapping) shall be provided.

2 At present Fire Hydrant System is not provided at various locations like DM Plant, RO Plant, P.T Plant area, 132 KV Switch yard and 66 KV Switch yard. Provision of Fire Hydrant System at these locations shall be under the scope of bidder.

3 All pipelines and valves shall be painted with anti-corrosive painting. 4 The quantity and size of pipes and valves are indicated in BOQ. 5 As the proposed hydrant pipe work system is branched from the existing hydrant

header, the hydrant pipe network shall be kept pressurized through the jockey pump (1 working + 1 stand by) taking care of any leakages in the system pipe lines and valve glands. In the event of fire, when any of hydrant valves in the net-work is opened, the resultant fall in header pressure should enable starting the existing AC motor driven Fire water pumping set through pressure switches automatically.

In the event of this pump failing to start or not, the system water pressure should fall further; and actuate another pressure switches in the system to enable starting the existing diesel driven pump automatically. Failure of the pumps to start on demand shall be signalled by an alarm in the Alarm annunciator panels located in the main plant control and fire station.

6 The existing hydrant system for unit No.1 and 2, coal plant is under ground, it needs replacement to above ground.

8 The mains should be laid according to the provisions given in IS 5822:1986 and IS 10221:1982 as applicable.

9 The ground hydrants system should normally not be extended to feed riser main in storeyed buildings. Only in special circumstances building not exceeding 15m in height, an extension may be used, provided sufficient output and pressure can be ensured from the system. In such cases, since ring mains may not be possible, terminal main of not less than 100 mm diameter to feed up to three hydrants and 150 mm dia to feed pump to five hydrants may be used.

10 Fire fighting mains should not be utilized for any other purpose such as process use for industrial premises.

B Fire hydrants

1 Fire hydrants, namely, stands post type conforming to IS 908:1975 and underground type conforming to IS 909: 1975 should be provided. For use in industrial, establishment, only stands post type hydrants should be provided.

2 Minimum terminal pressure of 3.5 Kg/Cm2 shall be maintained at farthest /remotest hydrant point.

3 Hydrants outlet and valve for the underground and valves for the stands post type hydrant should be located as near the ground level as possible. The top of the outlet or spindle of the valve should be at a depth not exceeding 0.3 m.

4 Ordinary manhole covers of cast iron or reinforced concrete should not be used to cover underground hydrants or the valves of the stand post type hydrants. They should be covered only by hinge cast iron covers as specified in IS 3950:1979 with letters FH embossed on them.

5 Apart from painting the fire hydrants and their covers in distinctive colours, all fire hydrants should have suitable indicating plates, fixes to the nearest wall or suitable post erected for the purpose to facilitate easy location. The indicating plates can be made of vitreous enameled mild steel, cast iron, aluminum alloy or plastic. The plates should be yellow in colour with letter “H” in black preferably with fluorescent colour paints. Were possible, size of the mains and the distance of the hydrants from the plates should be marked on the palte.

6 In case of industries of high hazard category [Gr G-3, H, and J] the Hydrants should be installed at every 30 m apart along building line the hydrants outlet should be single or double hydrants with provision of landing valves. For moderate hazard [Gr G-2] where the single hydrants it use, it should be installed at every 45 m apart. In case of any portion which has multiple hazards, the relevant portion should be covered according to the provisions given for higher hazard. Further, the pressure available at hydraulically most remote hydrants should not be less than 3.5 kgf/cm2 for light [group A to F] and moderate hazard. In case of high hazard [Group G-3, H and J], the hydrants system group-2] should be so designed that, when half aggregate pumping capacity is being discharged at the hydraulically most remote point and other held in the most vulnerable area enroute a minimum pressure of 5.25 kg/cm2 is available at the remote point. For group classification IS 1641:1988 should be referred.

7 The hydrants should be located according to the attendant fire hazard so as to facilitate the most effective service. They need not necessarily be equidistant from each other. In industries where they are to cover specific buildings advantage should be taken of convenient door or windows or both, to place hydrants so that, only a minimum length of hose is required to reach the opening through which fires may be attacked. The location of hydrants landing valves on floors above the ground floor or a processing unit should be close to the stair case landings.

8 Hydrants should be located at a distance of not less than 2 m from the face of the buildings. The distance may suitably be increased up to maximum 15 m where hydrants are installed to protect hazardous storages or processes so that, the hydrants remain approachable and workable even in the case of a serious fire.

9 All hydrants should be readily accessible to the fire appliances and for fire fighting operations.

10 Hydrants located in situations where they are likely to be damaged by vehicular traffic should be suitably protected on all sides against possible damage.

- 14 -

of 34

11 In cold climates, where frost is likely to be experienced the hydrants should be fitted with suitable means for draining off the water trapped in the body of the hydrants between the valve and the outlet.

12 No portion of a protected building should be more than 45 m from an external hydrants, and where this requirement can not be met, internals hydrants / landing valves should be provided [see IS 3844:1966].

13 Hydrants accessories, such as hydrants stand pipes, hydrants key and bar suction collecting heads, delivery hoses, branch pips and nozzles, etc. should be provided in sufficient quantities for quick operation of the hydrants.

14 In case of industries having their own fire brigades, the hydrants accessories should be provided centrally on each of the fire appliance and at the fire station. However, in the case of industries, which do not have their own brigade or where it is intended that, the trained workers will engage in interim fire fighting, the appropriate essential accessories should be provided near each hydrants points in hydrants boxes of adequate size. In such case of two, 63 mm hoses generally conforming to type A to IS 636:1988 duly bound with instantaneous couplings in 15 m length and one branch pipe duly fitted with a nozzle [preferably universal branch conforming to IS 2871:1983]. The key and other accessories should be provided according to the peculiar needs of each system.

15 All hydrant valves should be of stainless steel confirming to IS:5290.
