Foam:
As soon as the foam falls on the burning surface, it is removed from the coating, blocking
the access of oxygen, and the resulting liquid cools the burning surface. Foam is used mainly for
extinguishing solid substances and flammable liquids. According to its appearance, there are two

alkali solution, which is obtained by mechanical mixing of the foam-forming mixture with
airflow.
