Flammable liquid fires cannot be contained with water alone and require foam for extinguishment. Foam, mixed with water, blankets the liquid that is on fire, eliminating the oxygen supply and extinguishing it.
AFFF and FFFP foams have recently come under scrutiny as a potential groundwater contaminants. Accordingly, new environmentally friendly alternative foam agents are being developed and are just now coming to market.
Discharge testing of AFFF and FFFP foam systems should be suspended immediately. To learn more about how to responsibly dispose of your existing foam concentrates and to upgrade your system to a new agent, contact Keystone today.
