Foam Fire Extinguishing System

High and Low Pressure CO2 System Foam used in fire protection is an aggregate of air-filled bubbles formed from aqueous solutions, and is of lower density than the lightest flammable liquids. It is mainly used to form a coherent floating blanket on flammable and combustible liquids to prevent or extinguish fires by excluding air and cooling the fuel. It then prevents re-ignition by suppressing the formation of flammable vapours, and also adheres to surfaces, providing a degree of exposure protection from adjacent fires.
Foam can be used as a fire prevention, control or extinguishing agent for flammable liquid in tanks or processing areas.

Low expansion foam

Low Expansion foam offers a 5:1 expansion rate, making it the foam system of choice in Australia to protect large and hazardous facilities, including; petro-chemical tank farms, loading docks, processing areas and refineries and liquefied natural gas storage.

Organisations storing or handling flammable and combustible liquids will usually need to comply with Australian Standards AS1940 ‘The Storage and Handling of Flammable and Combustible Liquids’ and Gielle can provide the design expertise and system components to help any facility comply with this Standard.

High expansion foam

With an expansion rate of 500:1, High Expansion foam systems are more suitable to protect less common three-dimensional hazardous facilities including; warehouses, conveyors, aircraft hangars and tunnels.

As such, high expansion foam is measured by volume output rather than application rate, as is typical of low expansion foams.

With both low and high expansion foam systems, once a facility has been evaluated either an ‘Aspirating’ or ‘Non-Aspirating’ discharge device’ will be recommended, based on the facilities requirements.

For maximum effectiveness the expansion ratio, discharge device and foam concentrate must be correct. With our knowledge and expertise, Gielle can recommend the most appropriate devices for your situation.
