The expanded foam from which the film is drained forms a stable blanket that. Aqueous Film Forming Foam AFFF Alcohol Resistant AR-AFFF Synthetic medium or high expansion types detergent Class A Foam Concentrate Wetting Agent Fluoroprotein Protein Film Forming Fluoroprotein FFFP AQUEOUS FILM FORMING FOAM CONCENTRATE AFFF. Used to extinguish Class A materials such as wood paper and brush wildland is widely used by many fire departments for structural firefighting using compressed air foam systems.

Fluoroprotein foam FP is made by the addition of special fluorochemical surfactants to RP foam. Fomtec AFFF 1 A is an aqueous film forming foam concentrate AFFF consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents preservatives and stabilisers.

Because the foam can form a film the foam blanket can be effective at lower foam expansion values such as 31 to 51. Given the lower level of intensity in these types of fires Class A foams do not contain PFAS. This is a biodegradable mixture of foaming and wetting agents.

There are two major types of firefighting foam Class A foam and Class B foam with AFFF falling under Class B. Typically this category of firefighting foam is used to extinguish fires caused by wood paper or brush. SFFFs rely solely on the foam blanket to extinguish the fire.

Because there is not PFAS in the formulation SFFFs do not form this aqueous film. When proportioned with water Class A concentrates reduce the solution surface tension and allow greater penetration of the foam into most Class A fuels. Environmentally responsible Responder a Class A foam concentrate.

Both are synthetic firefighting foams for class A and B fires. Class A foam is used on common combustibles such as paper wood and textiles. Fomtec AFFF 1 A is intended for use on class B hydrocarbon fuel fires such as oil diesel and aviation fuels.

When mixed in correct proportions with water it can change two properties of the water. Available in either a 1 3 or 6 type concentrate. It is not Class A foam regardless if you dilute the Class B or not.

Used to extinguish Class B materials which include gasoline oil and jet fuel. It can be applied to Class B liquid spills to prevent ignition. Its obvious that Class A foam is used to fight Class A fires and that Class B foam snuffs out the Bs.

The two major classes of Firefighting Foam. An anti-freeze charge can be added to provide freeze protection to -40F. Foam Concentrate Water Air Mechanical Agitation FOAM TETRAHEDRON Suppresses Vapor FUEL Excludes Oxygen VAPORS Cools 2.

AR-AFFF exhibits the best cross-functional performance for flame knock-down burnback. Flammable liquid Class B fires. All Class B foams are not the same.

Including aqueous film-forming foam AFFF or alcohol-resistant aqueous film-forming foam AR-AFFF or protein foams. MID-EXPANSION Expansion ratio from 201 to 2001. Per- and polyfluoroalkyl substances PFAS are the active ingredients in fluorosurfactants.

Angus Fire have published a video on YouTube of a comparison of Angus Tridol S6 AFFF-C6 and Fluorine Free Foam tested according to ICAO Level B and EN1568-4. Class B Foam also called AFFF. By increasing your knowledge about the two different types of foam youll be confident in knowing when where and how to use Class A and Class B foam to achieve fast safe suppression for any type of fire situation.

An AFFF Foam fire extinguisher is effective on Class A and Class B fires. Use Discharge and Disposal of Firefighting Foam Products. Class B foam is.

Class A foam is used on common combustibles such as paper wood and textiles. Recently performed a head to head test with Novacool versus Class A and AFFF foam. These foams which include.

The foam forms an aqueous film that rapidly cuts off the oxygen supply and knocks down the fire. A Loaded Stream fire extinguisher is effective on Class A fires. In the same issue a related article by V Frank Bateman - At the Heart of It - examines some of the possible outcomes of dealing with flammable liquid fires using F3 foams instead of AFFFs.

If a Class B or AB foam concentrate label does not specifically state that the foam is fluorine-free the foam likely contains PFAS. ANSULITE Alcohol-Resistant Aqueous Film-Forming Foam AR-AFFF Concentrates produce a foam that is effective on hydrocarbon fuels as well as fuels such as methanol methyl alcohol ethanol ethyl alcohol and acetone which have appreciable water solubility or miscibility. CHEMGUARD Class A foams cling to surfaces such as charred.

CHEMGUARD Class A foam concentrates combine foaming and wetting agents for use in a variety of firefighting applications. Qualified to USDA Forest Service 5011-307a and UL approved for use as a wetting agent for Class AB applications. Class A foam can be produced using numerous types and configu-rations of equipment which are discussed later in some detail.

The ratio of class A foam concentrate to water is typically 01 to 10 percent. Foam has also been used successfully on Class A fires where the cooling and penetrating effect of the foam solution is important. There are two major types of firefighting foam Class A foam and Class B foam with AFFF falling under Class B.

Responder is designed for use in Class AB foam systems and is excellent for Compressed Air Foam Systems CAFS. To download a PDF of this article please click here or it can also be read online here. Class B foam is used on flammable liquids.

They are ideal for emergency first response vehicles. Advantages of Class A Foam Increase the effectiveness of water Extend the useful life of water Provide short-term fire barrier. So-called C6 foam products contain PFAS.

PHOS-CHEK 3 AFFF is our systems level foam with our most extensive. PHOS-CHEK foam concentrates are ideal for use in fixed foam systems in industrial facilities and is compatible with standard proportioning and foam making devices including bladder tank with proportioning devices foam chambers foam makers sprinklers self-inducting type nozzles and in-line proportioners.
