Fire fighting pump house & fire hydrant system Isolated pump house for fire fighting has been envisaged for the factory. A fire hydrant network system has been envisaged for the factory. Internal hydrants will be provided at suitable locations and at different levels inside the major factory units. Yard hydrants will be provided normally along the road and in the close vicinity of the units to meet the additional requirement of water for extinguishing fire. Hydrant system will have dedicated pump house, pumps, water storage and piping network etc. Water mist system Water mist system has been envisaged for protection of transformers (more than 10 MVA or having oil more than 2000 liters). Water mist system is a fire protection system which uses very fine water sprays (i.e. water mist). The small water droplets allow the water mist to control, suppress or extinguish fires. Adequate water pumping system will also be provided for operation of water mist system. The system will be designed as per latest edition of NF PA-750. The system will operate at working pressures of 7 to 16 bar, producing droplets of water through specialized engineered discharge nozzles for protected hazards. The fine mist generated following operation will be designed to limit fire growth at an early stage, before the fire can fully develop. The system is cost effective, less bulky and more effective. Benefits can be found through lower water demands, translating into lower pressure loses, smaller diameter pipes and lower installation costs when compared to traditional sprinkler systems. The system uses only water as its extinguishing media, as such produces no adverse environmental impact. NOVEC fire protection system Clean agent based (NOVEC 1230) fire fighting system is a very effective measure to control electrical fires. It will be provided in all control rooms and other locations of aviation importance. It will be provided in all premises having sophisticated and expensive equipment. NOVEC-1230 fire fighting system will be provided in areas including above false ceiling and below false floors of control rooms. NOVEC-1230 is based on a proprietary chemical from 3M called a Fluoroketone. NOVEC 1230 fluid is applied as gas but it is liquid at room temperature. It is electrically non-conducting in both liquid and gaseous state. The breakdown voltage of NOVEC 1230 fluid vapour under saturated conditions is nearly 2.3 times than that of dry nitrogen. NOVEC 1230 has a very low heat of vaporization, approximately 25 times that of water. This along with higher vapor pressure causes NOVEC 1230 to evaporate more than 50 times faster than water. This allows the agent very rapidly when discharged through nozzles. The system will be so designed so that the fluid gets evenly distributed throughout the protected space.

Respirators Self-contained, automatic positive pressure respirators (30 minutes duration) complete in all respect will be supplied, which will confirm to IS: 10245 (Part-II) – 1982. Complete equipment will have approval of the Director General of Mine Safety (DGMS), Dhanbad and will also have the approval of the Chief Controller of Explosives (CCE), Nagpur for high pressure cylinder and valves. The respirators will be fitted with full vision face masks, demand valve, warning whistle, steel alloy cylinder mounted on cushioned padded back plate, pressure reducing valves, pressure gauge, supply hoses, harness etc. The air required for respirators will be contained under pressure (Approx. 210 bar) in cylinder mounted vertically on a frame, which will be designed to assume the shape of the user’s back. Valve will be fitted at the lower end of the cylinder. The compressed air will be decompressed by means of a pressure reduce, which in turn will supply air to the regulator, connected to the lower part of the mask to supply air as required by the user. An audible warning whistle will sound an alarm, when the cylinder pressure drops to a danger level (8 to 10 minutes before the remaining air is released). One no. spare cylinder will also be supplied in addition, for each respirators set. Explosimeter Explosimeter will be supplied complete with full set of accessories for detected the combustible gas/vapour and measuring/indicating the concentration of these gases/vapours including methane and other hydrocarbons present in the atmosphere. The explosimeter will give automatically audio-visual alarm in case the concentration of combustible vapour/gas reaches the present danger level in the atmosphere. The explosimeter will be powered by a set of dry cells (1.5 V each). The range of sensing will be 0 to 100% Lower Explosive Limit (LEL). The explosimeter will be portable, with built-in filter to avoid entry of dust into instrument. The explosimeter will detect the gas concentration through catalytic combustion sensor. The equipment will have accuracy of 5% of full-scale reading and a response time of 3 seconds for 90% of final reading. The explosimeter will also have a nonconductive probe with 1 meter long sampling hose, a carrying case with shoulder strap and two-filter element. The explosimeter will have the approval from the Chief Controller of Explosives, Nagpur.

Make up water will be fed into the two compartments of fire water pump house RCC sumps. Pumps will be installed in a fire water pump house of civil construction having RCC columns, brick walls and RCC roof slabs. Range of operation will be 0 to 150%. Pumps will be self-water lubricated. TEFC electric motors rated for 415V, 50 Hz will be provided for the motor driven pumps. Coupling between pump and motor will be flexible coupling. Suitable diesel engines with automatic governing system for diesel engine driven pumps will be provided. Pump and engine will be connected through a gear box. Fuel for the engines will be LDO/HSD. The diesel engine will conform to the requirement of TAC.

Indicative fire water pump house arrangement

Fire hydrant system

All fire hydrants will be single outlet type and will consist of valve, matching flanges, CAF gaskets, nuts, bolts, blank cap & chain, spring lock type female outlets, etc. Each internal hydrant will be complete with hoses complete with hose coupling, nozzle, spanner, etc. Each outdoor hydrant will be provided with stand pipe with bend, hoses, couplings, spanners, nozzles, etc. In case of fire, when any landing valve/yard hydrant is opened, the water pressure in the respective network will drop resulting in automatic starting of main electric pumps for respective system at the pre-set low pressure in the headers. If the main electric pumps for hydrant fails to start or trips, the diesel engine driven pumps will start automatically.

Sprinkler system Automatic sprinkler are provided in car parking area. Sprinkler system are temperature dependent system. Every sprinkler consists of bulb which bursts at
