First Strike Class A
Class A FoamFirst Strike is a synthetic firefighting foam designed for Class A applications which include structural fires, forest and wild land fires, landfill fires and tire fires. The chemical balance in First Strike reduces the surface tension of water, which increases the penetrating and wetting abilities of the water and making the water supply five times more effective than untreated water. First Strike superior foaming ability provides firefighters protection from exposure to fire and the ability to lay down fire breaks in wild land fire situations. First Strike is biodegradable, non-toxic, non-corrosive nor harmful to the environment.
