Foam Fire Extinguisher

Applied to fuel fires as either an aspirated (mixed & expanded with air in a branch pipe) or non aspirated form to form a frothy blanket or seal over the fuel, preventing oxygen reaching it. Unlike powder, foam can be used to progressively extinguish fires without flashback. AFFF  (aqueous film forming foam), used on A and B fires and for vapor suppression. The most common type in portable foam extinguishers.
