AFFF Firefighting Foam: The Complete Guide

Blog Article

AFFF means “aqueous film-forming foam.” It's a kind of Firefighting Foam that is most commonly utilized by firefighters to extinguish Class B and Class A fires. Class B fires are the ones that involve flammable liquids, such as 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 at first glance 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 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 type of firefighting foam that's most commonly employed 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 know how AFFF works, it is 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 will go out. This is where AFFF comes in. When placed on a fire, AFFF forms a slim 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 diesel fuel or crude oil. Without surfactants, these types of liquids would repel water, rendering it hard 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, as well as many fire departments over the country.

● The principal 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 conditions, nevertheless they failed to warn the public 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 now been connected to cancer, in addition to, other health problems. The plaintiffs, in this case, are seeking compensatory and punitive damages. They're also seeking to have the companies remove these chemicals from AFFF firefighting foam and other products.

Aqueous film-forming foam (AFFF) is a significant tool in the combat 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.
