HVG FIRE FIGHTING EQUIPMENT 0229: 3% AFFF Foam Extinguishing Agent

3% AFFF Foam Extinguishing Agent is used on A and B fires and for vapor suppression. Alcohol-resistant aqueous film-forming foams (AR-AFFF), is used on fuel fires containing alcohol. It Forms a membrane between the fuel and the foam preventing the alcohol from breaking down the foam blanket. Applied to fuel fires as either an aspirated (mixed and 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.
