The Dangers of AFFF Firefighting Foam - How It's Ruining Families

Blog Article

AFFF stands for “aqueous film-forming foam.” It's a kind 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 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 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 easier and evenly over the top of the liquid.

How AFFF Works
● Aqueous film-forming foam (AFFF) is a type 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 understand how AFFF works, it's first very important to know the way fire works. Each time a fire burns, it will so because three elements exist: oxygen, heat, and fuel. The oxygen supplies the air necessary 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 three elements is removed, the fire should go out. This really is where AFFF comes in. When applied to 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 specifically important when fighting fires involving liquids with high surface tensions, such as for instance diesel fuel or crude oil. Without surfactants, these kind of liquids would repel water, making it burdensome for firefighters to extinguish them.

AFFF Firefighting Foam Lawsuit
AFFF Firefighting foam lawsuit is just a class action lawsuit which was filed in the United States District Court for the District of South Carolina. This device has been employed by the U.S. Military, in addition to 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, however they didn't warn people or take steps to eliminate the chemicals from the product.

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

● These chemicals have been associated with cancer, along with, other health problems. The plaintiffs, in this instance, are seeking compensatory and punitive damages. They are also seeking to truly have the companies remove these chemicals from AFFF firefighting foam and other products.

Aqueous film-forming foam (AFFF) is a significant tool in the fight fires. By forming a thin 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.
