FIRE
- 2. In order thata fire takes place, there has to be :- •Oxygen to sustain combustion. •Heat to raise the material to its ignition temperature. •Fuel or combustible material. A combination of ‘all’ of the above creates a fire!!
- 3. But how dowe fight a fire?? Fires can be extinguished by Breaking The Fire Triangle. Essentially, fire extinguishers put out the fire by taking away one or more elements of the fire triangle. When you cut off the heat, it is called cooling When you cut off the fuel supply, it is called starving When you cut off the oxygen, it is called smothering When you attack the fire at the ionic level, it is called inhibition
- 4. TYPES OF FIRES: ClassA fires occur in ordinary combustible material such as wood, cloth, paper etc…. Class B fires occur in the vapour-air mixture over the surface of flammable and combustible liquids like petrol, diesel, alcohol etc…. Class C fires involve gases such as LPG, CNG etc. and energized electrical equipments. Class D fires occur in combustible metals such as manganese, potassium, sodium etc….

- 17. LIFT DO NOT USELIFT TO ESCAPE
- 18. IF POSSIBLE, USEFIRE EXTINGUISHER
- 19. TYPES OF FIREEXTINGUISHERS There are different Types of Fire Extinguishers for different Type of Fire. Selecting the appropriate Fire Extinguisher is very important.
- 20. TYPES OF PORTABLEFIRE EXTINGUISHERS • WATER CO2 • FOAM (AFFF) • DRY CHEMICAL POWDER (ABC, BC, D) • GAS (CO2, CLEAN AGENT)
- 21. WATER CO2 FIREEXTINGUISHER These are specially designed for tackling Class A fires (wood, paper, straw, textiles, coal etc.) They fight the fire by cooling, smothering and starving in combination.
- 22. FOAM FIRE EXTINGUISHERS These are ideally suited where class A & B fires Aqueous Film Forming Foam or AFFF is particularly suited to fight liquid spill fires such as petrol, oil, fats, paints etc. It works by forming a film on the liquid hence smothering and cooling the fire.
- 23. CO2 FIRE EXTINGUISHER Theseare suitable for class B & C Class of Fire involving flammable liquids for electrical equipment. They cool and starve the fire.
- 24. POWDER FIRE EXTINGUISHER These are multipurpose fire extinguishers suited for all three types of fires ie A, B&C. They are also suited for D class of fire when filled with special powder. They fight the fire by smothering, starving and inhibition.
- 25. CLEAN AGENT FIREEXTINGUISHER These are suitable for A B & C Class of Fire. They are environmental friendly They are harmless to your electric and other equipment They leave no residue! Hence, they are called ‘Clean Agents’!!
- 26. HOW TO OPERATEA FIRE EXTINGUISHER Firstly, READ the instructions on the sticker on the extinguisher!!!! Remember (P.A.S.S.): Pull, Aim, Squeeze, Sweep. P - Pull the safety pin from the handle. A - Aim the extinguisher nozzle or hose at the base of the fire. S - Squeeze the handle to discharge the agent. S - Sweep side to side.
