Extinguishing media (FORM)

-
Liquids having a specific gravity lower than that of water are much difficult for extinguishing with the use of water. When water is put to the burning surface of a liquid, it lower the temperature momentarily and then sinks below the surface of the liquid. Form is relatively insoluble in most liquids and because of its light weight , floats on the surface of the liquids. It forms a blankets capable of covering the surface of the burning liquid & so extinguish  the fire .It also forms a radiant heat barrier , which is of importance in extinguishing oil and petrol fires.
