1960s DuPont "buried about 200 drums of C8 on the banks of the Ohio River near the plant." [10] 1963 The United States Navy scientists began to work with 3M to develop aqueous film-forming foams (AFFF). The US military began to use AFFF since its development in 1963 and patented AFFF in 1967. [22] [23]
In the 1940s, Percy Lavon Julian developed an improved type of foam called Aerofoam. Using mechanical action, a liquid protein-based concentrate, made from soy protein, was mixed with water in either a proportioner or an aerating nozzle to form air bubbles with the free-flowing action. Its expansion ratio and ease of handling made it popular.
AFFF was developed in the 1960s under Project Light Water in a joint venture between 3M and the U.S. Navy. AFFF forms a film that floats out before the foam blanket, sealing the surface and smothering the fire by excluding oxygen. AFFF is widely used for ARFF firefighting at airports, often in conjunction with purple-K dry chemical.
