AFFF Firefighting Foam: All That You Need to Know

AFFF represents “aqueous film-forming foam.” It's a type of Firefighting Foam that's most commonly employed 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 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—that really help the water to spread quicker 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 employed by firefighters to extinguish Class B and Class A fires. Class A fires are those 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 important to know the way fire works. Whenever a fire burns, it does so because three elements are present: oxygen, heat, and fuel. The oxygen offers the air essential for combustion, while the 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 applied to a fire, AFFF forms a slim 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 allow it to be 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 diesel fuel or crude oil. Without surfactants, these types of liquids would repel water, which makes it hard 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. The product has been used by the U.S. Military, along with many fire departments throughout 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 problems, but they didn't warn the public or take steps to get rid of the chemicals from the product.

● The chemicals at issue, in this instance, are perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).

● These chemicals have now been associated with cancer, as well as, 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 an important tool in the combat fires. By forming a slim layer of water at first glance 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.
