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

AFFF functions 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 surface tension of water—that assist the water to spread more easily and evenly over the surface of the liquid.

How AFFF Works
● Aqueous film-forming foam (AFFF) is a type of firefighting foam that's most commonly utilized 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 is first important to know the way fire works. Each time a fire burns, it will so because three elements can be found: oxygen, heat, and fuel. The oxygen offers the air required 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 three elements is removed, the fire should go out. That is where AFFF comes in. When put on a fire, AFFF forms a slim layer of water at first glance 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 allow it to be 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 for instance diesel fuel or crude oil. Without surfactants, these kind of liquids would repel water, making it burdensome for firefighters to extinguish them.

AFFF Firefighting Foam Lawsuit
AFFF Firefighting foam lawsuit is really a class action lawsuit that has been filed in the United States District Court for the District of South Carolina. The product has been utilized by the U.S. Military, in addition to 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, but they failed to warn the public or take steps to get rid of the chemicals from the product.

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

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

Conclusion:
Aqueous film-forming foam (AFFF) is a significant tool in the combat fires. By forming a thin layer of water on top 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.
