How many types of foam concentrate are there?

      Foam concentrate is a critical component used in firefighting to suppress fires effectively. It is a specially formulated solution used to produce foam that is applied to the surface of a fire to extinguish flames and prevent re-ignition. There are several types of foam concentrate available in the market, each with unique properties that make them suitable for specific applications. In this article, we will discuss the different types of foam concentrate and their uses.
1. Alcohol Resistant Foam Concentrate (AR-FFFP)
AR-FFFP foam concentrate is used in fires involving hydrocarbon fuels such as gasoline, diesel, and jet fuel, where a barrier is required to prevent the burning fuel from reigniting. This type of concentrate can handle the presence of alcohols, making it ideal for fires involving ethanol and methanol. AR-FFFP foam concentrate has excellent wetting properties and can penetrate through spilled fuel to extinguish flames.
2. Aqueous Film Forming Foam Concentrate (AFFF)
AFFF foam concentrate is widely used in Class B fires involving flammable liquids such as gasoline, diesel, and oil. It creates a film on the surface of the fuel, preventing the vapors from igniting. AFFF foam concentrate is known for its quick knockdown properties and is used extensively in airports, petrochemical facilities, and military installations. AFFF foam concentrate is also compatible with dry chemical powders and can be used in combination with them for added fire suppression.
3. Protein Foam Concentrate
Protein foam concentrate is used primarily in Class A fires involving organic materials such as wood, paper, and textiles. It is an economical and highly effective foam concentrate that creates a thick blanket over the burning material and smothers the fire. Protein foam concentrate is also used in some Class B fires involving polar solvents such as acetone and ethanol.
4. Fluoroprotein Foam Concentrate
Fluoroprotein foam concentrate is a versatile foam concentrate that is effective on both Class A and B fires. It is primarily used in aviation and industrial applications where it is desirable to minimize damage to equipment and facilities. Fluoroprotein foam concentrate is a blend of protein foam concentrate and fluorochemical surfactants. It is known for its ability to produce dense foam that adheres to vertical and horizontal surfaces, making it suitable for challenging fires.
