1. INTRODUCTION “Fire is an external sign of chemical action, usually the combination of Carbon and Hydrogen with Oxygen, resulting in the release of heat energy”. Fire is a necessary evil. When fire is under human’s control, it is a great asset. If human is under fire’s control, fire is a devastating foe. If fire occurs, how best can it be dealt with to extinguish? Firstly, by adopting the right mental attitude. With knowledge and ability, a fire fighter can attack a fire in the right manner and, by knowing its weakness, extinguish it in a short time. Without knowledge and ability, the fire will find out their weakness. For fire is a foe, against which no liberties can be taken. Fire should not be thought of as an intimate object. Fire, which starts unseen as a small flicker of flame, may grow at such a pace that it can quickly get out of hand. Once found, it must be extinguished with all the speed and means available or it will destroy those who seek to restrain it. Fire, when apparently extinguished, some untrained person may assume that because the flames have gone, the danger is passed, but it may not be so. Secondly, by considering each fire as an individual occurrence, the correct action in each case will depend on the position of the fire, the combustibles involved and the combustibles, which are in danger of becoming involved. There is no hard and fast rule; one who has the knowledge and training can only assert the correct action. Thirdly, by ensuring that properly maintained appliances are available for personnel to use and that all fire fighting, fire detection and alarm systems are in fully operational order. With the rapid growth of the industries and expansion of cities, fire hazards have also increased. Through considerable attention is being paid by the authorities concerned towards fire prevention and fire protection, a possible outbreak of fire cannot be detected and forestalled without an Automatic Fire Alarm System. In the absence of such a system, it is also not possible to ensure (a) an immediate transmission of call on the fire brigade in the event of an out break of fire in any premises during the closed hours, and (b) an effective control of a fire in the incipient stage, with the help of first aid and fire appliances. An Automatic Fire Alarm and Extinguishing System function through different type of detectors distributed in the premises to be protected, which causes the alarm to be actuated automatically, whenever there is possibility of a fire breaking out or immediately upon the outbreak of fire. The system helps evacuation of the premises, and extinguishes the fire as quickly as possible.

4.3.2 FIRE PUMP Starting & stopping of jockey & electric driven pumps are controlled through the pressure switches fitted in the hydrant and spray system headers. 4.3.3 HYDRANT SYSTEM The Fire Hydrant System shall consist of a network of pipe underground & overground which feeds pressurized water to no. of hydrant valves (indoor as well as outdoor) & water monitors. The Fire Hydrant System shall cover plant area with network of piping comprising of 150 NB, 100 NB & 80 NB pipe sizes shown in the enclosed layout drawing for fire hydrant system. The location of hydrant points in the plant is shown on the enclosed laying drawing. The fire water main network shall be maintained pressurized at all times to receive pressurized water at every fire hydrant system outlet within the plant. Pressurized water is being discharged in the pipeline with the help of two nos. 171 m3/hr. at 70 MWC head pump sets (one no. main electric driven pump + one no. stand by electric driven pump). One no. electric driven jockey pump of capacity 10.8 m3/hr. at 70 MWC head is provided in the system for keeping the system pressurized all the times. When the water requirement exceeds the quantity supplied by the jockey pump, fire main electric pump shall come into operation discharging water into the piping system, automatically due to higher pressure drop in the header. The pipe network is designed in such a way that any of hydrant outlet in the entire system delivery pressure shall not be less than 3.5 kg/cm2. The hydrant system in the yard shall be furnished with external hydrants, positioned app. one meter above the finished ground level, in accordance with statutory regulation for effective fire fighting.

OPERATION AND MAINTENANCE MANUAL

4.3.3 FIRE DETECTION AND ALARM SYSTEM All type of Detectors, Manual Call Points & Hooters are connected to the panel through Control cables. Panel scans all detectors and devices and gets digital information from the devices about their status. If any one detector or MCP senses fire, then it will be known to the panel while scanning. After getting this information panel will give audible output through internal sounder and also through field hooters in the corresponding area. It also gives visual indication through “Fire LED” Display”. The LED display will give the detailed information about the Area/Zone, in which the detector is placed. Also it will actuate the corresponding tripping contacts of ventilation fans, HVAC contacts. Similar kind of arrangement is made for Manual Call point.. Panel operator should silence the inbuilt sounder by pressing “Acknowledge” push button and note the details in the display. Based on the details one has to identify the fire and extinguish the same. After extinguishing the fire, the field hooters should be silenced through “Alarm Silence” Push Button and reset the panel through “Reset” push button. In case any manual call point has been actuated, replace the break glass before resetting the panel. Otherwise the alarm condition will come again within few seconds.

OPERATION AND MAINTENANCE MANUAL

5 SYSTEM OPERATION This section will explain how to operate the erected fire protection and detection system incase of a fire situation. As explained earlier in this manual, fire extinguishing will greatly depend on which the system is brought into action. Hence it is essential that the persons going to use the system are well aware about the following procedure. 5.1 HYDRANT SYSTEM 5.1.1 Operation of Hydrant valve Open the nearest hose box with the key provided. If the key is missing then break the glass door. Take the hose with coupling and branch pipes with nozzle from the hose box. Connect two hoses using hose coupling. Connect the branch pipe with nozzle to one end of hose having female coupling. Connect the other end of hose with male coupling to the hydrant valve. Hold the hosepipe with branch pipe and nozzle properly. Open the hydrant valve gradually. Play the water jet towards the seat of fire. 5.1.2 Operation of Water Monitor Release the lock nut for vertical movement of the monitor nozzle. Adjust the jet towards the fire vertically and lock it. Release the horizontal movement lock nut if required. Adjust the jet towards the fire horizontally and lock it. Open the Isolation valve provided in the monitor gradually.

FEC

OPERATION AND MAINTENANCE MANUAL

After the valve is opened, if the water is not playing on the seat of fire, adjust the horizontal and vertical locks to direct the water towards the seat of fire. 5.1.3 Operation of Fire Escape Hydrant Repeat the procedure as explained for hydrant valve.

5.3 FIRE DETECTION AND ALARM SYSTEM As the system is totally automatic in operation, manual intervention to operate the system is not required and only the system has to be reset for normal operation after a fire condition. Fire detection and alarm system operation can be classified in to two types.  

Automatic operation. Manual operation.

5.3.1 Automatic operation In Automatic Fire Alarm System, different types of Fire Detectors located at the various locations are connected to the Main Fire Alarm Panel through cables. During fire condition, the detectors will sense the fire and report it to the panel and does the necessary alarm (in panel and the field). Fore more details refer 4.3.7 5.3.2 Manual Operation In Manual Operation, during ‘fire’, the Manual Call Point’s "BREAK GLASS" has to be broken to initiate the alarm on the panel and the panel will do all the alarm, annunciation and controls. To reset the system for normal operation, "BREAK GLASS” of the Manual Call Point has to be replaced and the panel has to be reset through “Reset” Push Button. Purpose of this manual call points is to inform the panel about the fire condition when the fire is detected manually. Just by pressing the manual call point, the signal can be transferred to the panel. All the other operations of the panel shall be same as of automatic operation. When the manual call point is pressed the panel display unit will display the exact location of manual call point, so that the operator can identify the location and can take appropriate action to extinguish the fire. 5.4 PUMPS AND ACCESSORIES 5.4.1 Operation of Pumps for Hydrant System In the event of fire, when any hydrant valve is opened in any part of the network, the resultant fall in header pressure will bring the electric motor driven hydrant pump in to operation automatically to supply water to the hydrant system. Failure to start pump on demand will result in further fall in header pressure or if the header pressure still falls, even when pump is running, then the signal from pressure switch will open the motor actuated valve & simultaneously start the stand-by

OPERATION AND MAINTENANCE MANUAL

7 ROUTINE TESTING Even though the system is well designed and well installed, it is very much essential that the system is tested in a routine and maintained properly for getting the system to service when it is badly needed. It is desired to operate the system in automatic mode, as its need in an event of fire cannot be neglected. However, manual starting should not be ignored. To maintain both automatic and manual operating to keep intact, routine testing is vital. 7.1 PUMPING Automatic starting sequence of the pumps can be checked by periodically in the following manner. Open the nearest hydrant valve slowly and checkup the pressure at which the jockey pump starts. After five minutes close the hydrant valve completely and see whether the jockey pump stops automatically at 7.0 bar. Keep the jockey pump in manual mode and open the nearest hydrant valve fully. Check up the pressure at which the electrical driven main pump starts. After that close the hydrant valve and stop the pump manually. Repeat above by keeping jockey pump and main pump in manual mode and check the pressure at which the diesel engine driven standby pump starts. Engine shall also be manually started with batteries on line, once in a week to confirm the healthy condition of the battery. It shall be run on load for about 10 minutes. 7.2 HYDRANT SYSTEM It is recommended to carryout “wet-drill” once in a week at different hydrant points and monitor. This will have a check on all sections and will prevent settling of mud at valve seats and in pipes. It will also confirm that sectionalizing sluice valves are all open. 7.4 FIRE DETECTION AND ALARM SYSTEM Healthiness of the detector shall be checked visually by seeing the LED glowing. Every week the battery should be checked for the charge availability. Daily, Panel display shall be checked for any event happenings. If there is any fault the same should be attended immediately to rectify the same. 7.6 EXTINGUISHERS
