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 (CO2) 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
