AFFF Firefighting Foam: All That You Need to Know
Blog Article
AFFF represents “aqueous film-forming foam.” It is a form of Firefighting Foam that is most commonly used by firefighters to extinguish Class B and Class A fires. Class B fires are those who involve flammable liquids, such as for instance gasoline, oil, or paint, while Class A fires are those who involve combustible materials, such as for example wood or paper.
AFFF works by forming a slim 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—that assist the water to spread easier and evenly over the outer lining of the liquid.
How AFFF Works
● Aqueous film-forming foam (AFFF) is a kind of firefighting foam that is most commonly used 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 how fire works. When a fire burns, it does so because three elements can be found: oxygen, heat, and fuel. The oxygen supplies the air required 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. This 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 ensure it is 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 instance diesel fuel or crude oil. Without surfactants, these kinds 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 which was filed in the United States District Court for the District of South Carolina. The product has been used by the U.S. Military, in addition to many fire departments across the country.
● The primary allegations in the lawsuit are that the businesses knew or needs to have known that the chemicals in AFFF firefighting foam were dangerous and caused health problems, 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, 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 an important tool in the fight 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.
