AFFF represents “aqueous film-forming foam.” It is a type of Firefighting Foam that's most commonly utilized 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 those that involve combustible materials, such as for instance wood or paper.

AFFF works by forming a slim layer of water at first glance of the burning liquid, which effectively smothers the fire and prevents it from spreading. Additionally, AFFF contains surfactants—substances that reduce the top tension of water—which help the water to spread easier and evenly over the surface of the liquid.

How AFFF Works
● Aqueous film-forming foam (AFFF) is a type of firefighting foam that is most commonly utilized 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 know how AFFF works, it is first crucial that you know how fire works. Whenever a fire burns, it does so because three elements exist: oxygen, heat, and fuel. The oxygen supplies the air essential 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. This is where AFFF comes in. When applied to 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 especially important when fighting fires involving liquids with high surface tensions, such as diesel fuel or crude oil. Without surfactants, these kind of liquids would repel water, which makes it difficult 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. The product has been employed by the U.S. Military, along with many fire departments throughout the country.

● The primary allegations in the lawsuit are that the companies knew or should have known that the chemicals in AFFF firefighting foam were dangerous and caused health conditions, nevertheless they didn't warn the general public or take steps to get rid of the chemicals from the product.

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

● These chemicals have now been linked to cancer, along with, other health problems. The plaintiffs, in cases like this, 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 an essential tool in the fight against fires. By forming a thin 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.
