When “3-F” is added to a 15-25 lt. capacity back pump, the equivalent result is obtained by extinguishing with 150-250 lt. of water. Since there is limited water and product use in this method, the product concentrate can be increased. In these applications, it is recommended to use 1/3 of the product. In firefighting operations performed by adding “3-F” extinguishing and cooling product, the ambient temperature drops below 60 C 30 seconds after the application with the back pump, cooling continues rapidly and no further flare-up occurs. There is no need for a cooling process.
