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

AFFF functions by forming a slim layer of water on top 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 easier and evenly over the outer lining of the liquid.

How AFFF Works
● Aqueous film-forming foam (AFFF) is a kind of firefighting foam that's most commonly used by firefighters to extinguish Class B and Class A fires. Class A fires are those that 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 is first important to understand how fire works. Each time a fire burns, it will so because three elements exist: oxygen, heat, and fuel. The oxygen provides the air necessary for combustion, while the heat 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 put on a fire, AFFF forms a slim 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 specifically important when fighting fires involving liquids with high surface tensions, such as for instance diesel fuel or crude oil. Without surfactants, these types of liquids would repel water, making it problematic for firefighters to extinguish them.

AFFF Firefighting Foam Lawsuit
AFFF Firefighting foam lawsuit is a class action lawsuit that was filed in the United States District Court for the District of South Carolina. This system has been utilized by the U.S. Military, as well as many fire departments throughout the country.

● The principal 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 didn't warn the general public or take steps to remove the chemicals from the product.

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

● These chemicals have already been associated with cancer, along with, other health problems. The plaintiffs, in this case, are seeking compensatory and punitive damages. They are also seeking to have the companies remove these chemicals from AFFF firefighting foam and other products.

Conclusion:
Aqueous film-forming foam (AFFF) is an important tool in the combat fires. By forming a slim layer of water at first glance 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.
