AFFF means “aqueous film-forming foam.” It is a kind of Firefighting Foam that's most commonly used by firefighters to extinguish Class B and Class A fires. Class B fires are those who involve flammable liquids, such as for example gasoline, oil, or paint, while Class A fires are the ones that involve combustible materials, such as for instance wood or paper.

AFFF works by forming a slim layer of water on the surface of the burning liquid, which effectively smothers the fire and prevents it from spreading. Additionally, AFFF contains surfactants—substances that reduce the outer lining tension of water—that really help the water to spread more easily and evenly over the top of the liquid.

How AFFF Works
● Aqueous film-forming foam (AFFF) is a type of firefighting foam that is most commonly used by firefighters to extinguish Class B and Class A fires. Class A fires are those who involve combustible materials like wood or paper, while Class B fires involve flammable liquids like paint, oil, or gasoline.

● To understand how AFFF works, it's first important to know how fire works. When a fire burns, it will so because three elements are present: oxygen, heat, and fuel. The oxygen supplies the air necessary for combustion, while the warmth causes the fuel to ignite. Once ignited, the fuel begins to burn, releasing energy in the proper execution of heat and light.

● If one of these simple three elements is removed, the fire will go out. That is where AFFF comes in. When placed on a fire, AFFF forms a thin layer of water on the surface of the burning liquid. This effectively smothers the fire and prevents it from spreading. Surfactants, which lower water's surface tension, are another ingredient in AFFF. They make it easier and more uniform for water to spread across a liquid's surface.

● Surfactants are specially important when fighting fires involving liquids with high surface tensions, such as diesel fuel or crude oil. Without surfactants, these kinds of liquids would repel water, rendering it problematic for firefighters to extinguish them.

AFFF Firefighting Foam Lawsuit
AFFF Firefighting foam lawsuit is just a class action lawsuit that was filed in the United States District Court for the District of South Carolina. The product has been employed by the U.S. Military, in addition to many fire departments over the country.

● The primary allegations in the lawsuit are that the companies knew or needs to have known that the chemicals in AFFF firefighting foam were dangerous and caused health conditions, however they failed to warn people or take steps to remove the chemicals from the product.

● The chemicals at issue, in cases like this, are perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).

● These chemicals have already been linked to cancer, as well as, other health problems. The plaintiffs, in cases like this, are seeking compensatory and punitive damages. They're also seeking to truly have the companies remove these chemicals from AFFF firefighting foam and other products.

Conclusion:
Aqueous film-forming foam (AFFF) is an essential tool in the combat fires. By forming a slim layer of water on the surface of burning liquids, it effectively smothers flames and prevents them from spreading. Additionally, its surfactant content helps water to spread more evenly over surfaces with high surface tensions.
