The use of CAFS (Compressed Air Foam Systems) as a primary fire attack tool has now caught on thanks to positive reports involving front-line fire engines equipped with the Schmitz GmbH ‘ONE SEVEN’ system – many fire brigades across Europe have been following this innovative approach. Now this innovative extinguishing procedure is being used to protect recycling plants, reveals IFJ.
“Imagine you have to provide fire suppression for a mass of intermediate storage materials, such as paper, cardboard, paper board container and plastics with fire load heating values of more than 14 MJ/Kg. These pose a considerable risk for persons and buildings – and are a pollution threat,” points out industry expert Günter Knopf.
“Up to now, conventional extinguishing methods like low-expansion foam or water spray systems with a foam concentrate proportioning rate of 1% have been used to fight that type of fire.  Experiments to try to control fires in recycling plants or waste incineration plants with medium-expansion foam have been more or less successful.”
However, to protect depots and sorting plants improved fire detection systems and highly-efficient fire extinguishing systems must be the answer, he believes. He sees the ONE SEVEN compressed air foam extinguishing method as the way forward in this arena.
“The ONE SEVEN effect converts the water volume of a water drop onto the surface of seven foam bubbles of 0.5 mm. Through this, the heat bond of the extinguishing medium will be increased from 0.83°C/sec. of water to 10.3°C/sec. of ONE SEVEN compressed air foam. This results in a 12.4-fold faster heat bond compared to the extinguishing with water,” he tells IFJ.
“The cooling effect of ONE SEVEN reportedly exceeds the smothering effect of a conventional foam. These are proven and confirmed results from numerous tests performed by the Research Centre for Fire Protection Engineering of the University Karlsruhe (Germany),” he says.
The compressed ONE SEVEN foam generated in the Central Foaming Unit is supplied through pipelines and it projected by the discharge installations provided (nozzles, monitors, rotors). Distances of up to 1,000 metres length or 250 metres height to the discharge installation (throwing distance approximately 30 metres) are possible, he reports.
“Supplying the compressed air foam via long pipeline distances is possible without affecting the foam quality and the extinguishing features of the foam. The foam consistency will be completely preserved. This is especially decisive when extinguishing from large heights like in recycling depots for example,” reports Günter.
The ONE SEVEN compressed air foam can be applied to the seat of fire and cools it effectively, abruptly reducing smoke formation.
Everything hinges on a clear and accurate response from early fire detection, he argues. Combined with an automatic firefighting and extinguishing system. “What you need is to choose a fire detection system which clearly signals predetermined detection areas,” he says.
“This combination of earliest possible fire detection and immediate extinguishing with ONE SEVEN compressed air foam undoubtedly ensures the investor a failure-free operation of his recycling plant.” y
