AFFF represents “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 works 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 really 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 form of firefighting foam that is 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 understand how AFFF works, it's first very important to know the way fire works. Whenever a fire burns, it will so because three elements exist: oxygen, heat, and fuel. The oxygen offers 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 simple 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 on top 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 especially important when fighting fires involving liquids with high surface tensions, such as for example diesel fuel or crude oil. Without surfactants, these kinds of liquids would repel water, making it difficult 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, in addition to many fire departments over 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 conditions, nevertheless they didn't warn people 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 connected to cancer, in addition to, other health problems. The plaintiffs, in cases like this, are seeking compensatory and punitive damages. They're 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 combat 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.
