2025年1月17日 · These Settlements are designed to resolve Claims for PFAS contamination in Public Water Systems’ Drinking Water, as those terms are defined in the respective Agreements. Each of the four Settlements has obtained Final Approval by the MDL Judge, the honorable Richard M. Gergel of the United States District Court for the District of South Carolina.

2023年8月31日 · Aqueous film forming foam, or AFFF, is a fire suppressant used to fight flammable liquid fires. Firefighting training facilities and vehicles, ships and shore facilities and military facilities are some of the places AFFF is used. Toxic chemicals in some AFFF solutions may increase the risk of serious health problems, including cancer.

2024年4月26日 · Aqueous film forming foam (AFFF) is a synthetic, water-based surfactant designed as a Class B foam (designed for primarily gasoline fires). The foam smothers the...

水成膜泡沫（AFFF）灭火剂 aqueous film forming foam extinguishing agent 以 碳氢 表面活性剂 与 氟碳表面活性剂 为 基料 并能够在某些 烃类 液体表面形成一层水膜的泡沫灭火剂。

Aqueous film-forming foam (AFFF) is a highly effective firefighting product intended for fighting high-hazard flammable liquid fires. AFFF products are synthesized by combining hydrocarbon foaming

2024年3月8日 · Aqueous film forming foam (AFFF) has been the industry standard for combatting liquid fuel fires and hazards for almost 50 years. AFFF is a water-based solution that contains a fluorinated, film forming surfactant [per- and poly-fluoroalkyl substances (PFAS)] to seal the fuel surface during suppression/extinguishment.

Plaintiffs generally allege that aqueous film-forming foams (AFFFs) containing perfluorooctanoic acid (PFOA) and/or perfluorooctane sulfonate (PFOS), two types of PFAS, contaminated groundwater near various military bases, airports, and other industrial sites where AFFFs were used to extinguish liquid fuel fires.

AFFF is a combination of fluorocarbons, surfactants, and solubilizers. The fluorochemical based surfactant reduces the surface tension of water allowing the foam to form an aqueous film on the surface of the hydrocarbon fuel that: (1) suppresses vapors. (2) …

2024年5月3日 · Firefighting foams are aggregates of small bubbles that efficiently combat liquid fuel fires by forming a vapor-suppressing blanket over the fuel surface. Aqueous film forming foams contain 2–15% of stable perfluorinated molecules. Concerning toxicity, perfluorooctanoic acid has a half-life of more than five years in adult humans.

Aqueous film forming foam (AFFF) is a highly efficient type of fire suppressant agent, used by itself to attack flammable liquid pool fires, and in conjunction with Halon 1301 to attack fires in Navy vessel machinery spaces.
