1 Types of Fire Extinguishers

2 Three ways to extinguish a fire Starvation - Removal of fuel Smothering - Removal of oxygen Cooling - Removal of heat Remove any one of the three components and fire cannot start or be sustained

3 Fire classification Class A: SOLIDS such as paper, wood, plastic etc Class B: FLAMMABLE LIQUIDS such as paraffin, petrol, oil etc Class C: FLAMMABLE GASES such as propane, butane, methane etc Class D:METALS such as aluminium, magnesium, titanium etc Class F:Cooking OIL & FAT etc

4 Types of Fire Extinguishers Water 6 or9 litre size Suitable for Class A Fires Not for use on flammable liquids Not to be used near to live electrical apparatus Discharge time, approximately 60 seconds Weighs approximately 15 kilos

5 Types of Fire Extinguishers Foam Multi-Purpose Foam Spray 9 litres, 6 litres or 2 litres Ideal for burning solids and hydrocarbon liquids Can be rated for use on live electrical equipment

6 Types of Fire Extinguishers Dry Powder 1kg, 2kg, 3kg, 6kg, and 9kg capacities ABC powder for burning solids, burning liquids and if specially trained, burning gases Could be harmful in a confined space, and will contaminate prepared foods, and delicate electronic equipment Little cooling effect

7 Types of Fire Extinguishers SPECIAL FIRE EXTINGUISHERS ‘FryFighter’ For Class F Fires (overheated cooking oils/ fats) ‘Unique’ Wet Chemical’ formulation to suponificate the burning fat

8 Types of Fire Extinguishers Carbon Dioxide (CO 2 ) Clean non conductive agent Ideal for fires involving live electrical apparatus Noisy in operation Some parts of the extinguisher will become very cold Little to no cooling effect

9 Other Fire Fighting Equipment Hose - Reels Fire Blankets

10 Remember! Extinguishers are only for dealing with small fires. DO NOT CONTINUE TO FIGHT A FIRE IF: it is dangerous to do so, there is a possibility that your escape route may be cut off by the fire or smoke, the fire continues to grow in spite of your efforts, there are gas cylinders threatened by a fire.
