In fire extinguishing operations, portable back pumps are preferred for small, point fires that cannot be reached by air and land vehicles, but have the capacity to grow under adverse weather conditions. 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.
