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 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 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—that assist the water to spread easier and evenly over the surface 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 those who 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. When a fire burns, it does so because three elements can be found: oxygen, heat, and fuel. The oxygen supplies the air necessary for combustion, while heat causes the fuel to ignite. Once ignited, the fuel begins to burn, releasing energy in the shape of heat and light.
● If one of these three elements is removed, the fire will go out. This really 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 allow it to be easier and more uniform for water to spread across a liquid's surface.
● Surfactants are specially important when fighting fires involving liquids with high surface tensions, such as for example 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 really a class action lawsuit that was filed in the United States District Court for the District of South Carolina. This product has been utilized by the U.S. Military, as well as many fire departments over the country.
● The principal 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 eliminate the chemicals from the product.
● The chemicals at issue, in this instance, are perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).
● These chemicals have already been associated with cancer, as well as, 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 a significant tool in the fight fires. By forming a thin 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.
