AFFF means “aqueous film-forming foam.” It's a form of Firefighting Foam that is 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 the ones that involve combustible materials, such as wood or paper.

AFFF functions forming a thin 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 top tension of water—which help the water to spread quicker and evenly over the outer lining of the liquid.

How AFFF Works
● Aqueous film-forming foam (AFFF) is a type of firefighting foam that's most commonly employed 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 know the way AFFF works, it's first very important to know the way fire works. Each time a fire burns, it will so because three elements are present: oxygen, heat, and fuel. The oxygen provides the air essential 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 brilliant three elements is removed, the fire should go out. This really is where AFFF comes in. When applied to 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 ensure it is 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 example diesel fuel or crude oil. Without surfactants, these types 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. This system has been used by the U.S. Military, as well as many fire departments across 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 failed to 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 already been associated with cancer, along with, 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 a significant tool in the fight 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.
