AFFF means “aqueous film-forming foam.” It is a type 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 for example gasoline, oil, or paint, while Class A fires are those who involve combustible materials, such as for example wood or paper.

AFFF functions by forming a thin 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—which 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 kind of firefighting foam that is most commonly utilized by firefighters to extinguish Class B and Class A fires. Class A fires are the ones that 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 crucial that you understand how fire works. Whenever a fire burns, it will 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 brilliant 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 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 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 diesel fuel or crude oil. Without surfactants, these types of liquids would repel water, rendering it hard 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. This device has been utilized by the U.S. Military, as well as many fire departments throughout the country.

● The primary allegations in the lawsuit are that the firms knew or must have known that the chemicals in AFFF firefighting foam were dangerous and caused health issues, but they failed to warn the 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 been connected to cancer, as well as, 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 a significant tool in the combat fires. By forming a slim 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.
