GOING GREEN: The aqueous film-forming foam, or AFFF, used in Marine Corps Logistics Base Albany Fire & Emergency Services’ trucks, until recently, had an unknown amount of per- and polyfluoroalkyl substances. This presented a possible health risk.
Efforts were put in motion to replace the existing foam with something greener. The fire trucks now have an AFFF containing less than 3% of the product.
The entire class of approximately 600 per- and polyfluoroalkyl substances are commonly known as PFAS. The Department of Defense began using AFFF containing perfluorooctane sulfonate, or PFOS, and in some formulations perfluorooctanoic acid, or PFOA, in the 1970s. Both are two chemicals in the larger PFAS class.
AFFF is mission-critical because it quickly extinguishes petroleum-based fires.
