Responder® F3 Class A

Responder® F3 Class A Foam

Responder® F3 Class A foam concentrate is designed for municipal firefighters battling Class A and Class B fires and is excellent for Compressed Air Foam Systems (CAFS). This formulation does not contain reportable components under SARA Title III, Section 313 of 40 CFR-372, or CERCLA.

Class A foam concentrates work by reducing the surface tension of water, allowing the mixture to penetrate surfaces where water might normally run off. This decreases the amount of water required to extinguish the fire and increases the water’s contact time with the fuel surface. More contact time with the fuel surface means more heat absorption.
