- 1. Raghunath Patil FIRE FIGHTING Presentation By Raghunath Patil Chief Engineer
- 2. Raghunath Patil Fire Triangle Fire is caused according to the principle of triangle . 1. Heat ( temperature reaching ignition point ) 2. Combusting material( fuel) 3. Air Extinguishing Method 1. Heat by Cooling i.e. putting water 2. Air by Smothering / Blanketing i.e. covering 3. Fuel by Starving ( Remove burning material) Human brain without oxygen survive only 4 min. Fire extinguishes if oxygen supply stop for 2 Sec.
- 3. Raghunath Patil The success of fire fighting depends on Fire fighting equipments in working condition Fire warning system and quantity of extinguishers Fire training ( knowledge ) It is essential for everybody to know type of fire and then extinguish it with correct extinguisher in quick and effective manner.
- 4. Raghunath Patil Classification of fire 1. A class(Solid,wood,paper,etc) 2. B class (oil,paint,etc) 3. C class,(Gas,carbonmonoxide) 4. D class ( Metal,zinc,copper,etc) 5. Electrical fire.
- 5. Raghunath Patil Extinguishers:- 1. Water type :- Removes heat i.e. Cooling only for A class fire. 2. Foam type :-Cutting of Oxygen i.e. Smothering or Blanketing + cooling) Only on A,B fire 3. CO2 type :- Displace Oxygen i.e. smothering Use only on B,C,E fire 4. DCP type:- Cutting of Oxygen i.e. Smothering Use only B,C,E fire. If ammonium phosphate is used then it can be used on A class also.
- 6. Raghunath Patil Types of Extinguishers in ROGS Co2 AFFF DCP ABC Store Pressure Type DCP BC Cartridge Type
- 7. Raghunath Patil CO2 EXTINGUISHER Contains: Liquefied CO2 , 4.5 Kg at 1.125 PSI and at 16 degree . Operation :-Hold the extinguisher by trigger assembly . Remove safety pin Approach base of fire open the valve fully & sweep it. By this we are Cutting of Oxygen of fire called smothering Suitable for : B,C and Electrical Fire Note:- Do not grip the fiber hose or cylinder during use or you will get cold burn. It can not be used against A class of fire because there is no cooling effect CO2 escape in air. It can not be used against D class of fire because reaction takes place.
- 8. Raghunath Patil Co2 Extinguisher 4.5 Kg Co2 Gas under pressure
- 9. Raghunath Patil AFFF Type Contains : 550 ML Aqueous Film Forming foam Compound mixed with fresh water and one Co2 cartridge of 60-90 gm . Operation: Open the safety pin . Hold the hose towards base of fire. Strike the knob with left hand . Co2 cartridge will break and AFFF Foam with a pressure of 3.5 Kg /cm2 will come out. Sweep it on fire. By this we are Cutting of Oxygen of fire called smothering Suitable for:- A and B class of fire. Note: Not to use on Electrical and D class fire because of water reaction
- 10. Raghunath Patil AFFF Type (Aqueous Film Forming Foam) Extinguisher 1. AFFF chemical 2. Co2 cartridge 3. water
- 11. Raghunath Patil DCP ABC STORE PRESSURE TYPE Contains :Contains 5 Kg Mono Ammonium phosphate with nitrogen gas under pressure. It does not have cartridges . Operation : Remove the safety pin hold the hose to base of fire, press the handle and sweep. We can stop at any time in between by releasing handle. Nitrogen drives to jetting powder for extinguishing . By this we are cutting off oxygen of fire called smothering Suitable For: A, B, C and E class of fire only.
- 12. Raghunath Patil DCP Type (Dry chemical Powder ) Extinguisher 10 Kg DCP Contains 1) Mono Ammonium phosphate 2) Nitrogen
- 13. Raghunath Patil DCP BC CARTREDGE TYPE Note: Can not be used against A class of fire. Contains :Contains Sodium bicarbonate powder 5 Kg and Co2 cartridge 120-150 gm Operation : Remove the safety pin hold the hose to base of fire, Strike the knob with hand and sweep the hose on fire. We can not stop till the extinguisher finishes.Co2 drives to jetting powder for extinguishing . By this we are cutting off oxygen of fire called smothering Suitable For: B, C and E class of fire only.

For operating connect it to the hydrant point ( which is in the duct of each floor) and open the valve. Jet water will go upto 50 to 60 feet 30 Mtr hose reel also connected to the hydrant on each floor. This rubber hose reel of 1 inch width can be unroll and we can use with pressure nozzle There are fire buckets are kept near DG set, Gas bank and HT Panel room. They should not be removed or use for other purpose except fire fighting.
- 21. Raghunath Patil Action in case of fire 1. During break out of fire panic , nervousness and confusion should not be there. 2. Inform Reception and security by dialing 9 by nearest Tel. 3. Give the your name, exact location and size of fire 4. Action should be quick so that small fire can be extinguish immediately. The delay in action cause fire to grow and may become difficult to be controlled later 5. Stay on the fire area if safe to do so. Don’t panic .Try to extinguish the fire with extinguishers/fire hydrant hose. 6. If fire not under control , inform fire brigade and Evacuate Hotel 7. Follow the route for escape which is pasted on each door in room 8. Provide help to the guest for evacuation . 9. For guest assembly point is Porch area 10. For staff Lower parking area
- 22. Raghunath Patil YOU MUST KNOW 1. The place where the fire fighting extinguishers are kept . 2. The place where fire hydrant hoses and fire buckets are kept. 3. Fire hydrant points. 4. The telephone numbers of fire brigade , ambulance and police 5. what is the class of fire and what kind of of fire extinguisher can be used for this class of fire 6. Application of water on liquid fire and electrical fire causes fire to spread 7. The route for escape is marked and pasted on each door in room
- 23. Raghunath Patil DO’s and DONT’s 1. DO NOT allow to use lift. Use only staircase left side. 2. Do not run to fire zone without extinguisher. 3. Close window & door as you leave fire zone 4. Do not shout 5. DO NOT open door & not to switch on Exhaust fan 6. Do not waste time to collect personnel belongings. 7. Use wet towel on your mouth and nose 8.

- 24. Raghunath Patil EMERGENCY TELEPHONE NUMBERS 100 -- POLICE 101 – FIRE BRIGADE 102 – AMBULANCE 103 – TRFFIC POLICE 108 – NATIONAL EMERGENCY ALL THESE ARE TOLL FREE NUMBERS
- 25. Raghunath Patil CAUSES OF FIRE:- Housekeeping :- Poor house keeping is a poor fire hazard . Cotton , cloths, papers ,etc are the sources of ignition. They should be kept away from combusting material like petrol, oil ,etc. Smoking:- Careless smoking in non smoking areas should be stopped . Smoking shall be permitted in smoking zone only. Welding / gas cutting :- While doing gas welding or oxy-acetylene cutting produces flying sparks which falls on inflammable material and fire takes place.
- 26. Raghunath Patil Ignorance about fire hazards:- Lack of knowledge about the safe methods of storage of inflammable liquids, materials. Correct use of electrical equipments etc. Negligent habit :- Our negligent or careless habits are responsible for fire out break. A lighted match stick, cigarette end carelessly thrown on any combusting material . Kitchen:- Most sensible area to get fire in hotel. Kitchen staff should take extra care while preparing food. In kitchen because of carelessness oil fire and gas fire can take place. Electrical Panel Room: No material to be stored in electrical panel room. Small short circuit will be converted into big fire.
- 27. Raghunath Patil FIRE FIGHTING FIRE = Fire Inform Response Evacuate Fire is a good servant but bad master. So we must always keep fire under our control. And not allow fire to be our master. Fire is a serious danger to hotel buildings. Fire occurs usually because of negligence of any person who carelessly throws match sticks, cigarettes end or careless storage / handling of inflammable material. Calamities never come with a notice . If there has been no fire for long it means that the time for a fire break –out come near. If we prevent fire , the loss we going to suffer on account of fire that would be our gain. Prevention is better than cure . So we should pre-plan our fire prevention and fire fighting program
