Some of the aircraft used in firefighting operations can fill from natural water sources (sea, lake, pond etc.). Others can fill from depots or supply vehicles located at airports. Aircraft operating in this second section generally drop water or retardant products (in order to reduce the spread of fire). There is no need for a separate process for the water added with ‘‘3-F’’ from these aircraft. The application procedure for other products is the same for ‘‘3-F’’.
Extinguishing and cooling operations performed using the “3-F” product provide definitive results in a very short time.
