Question: How many types of fire foam are there?

What are the types of firefighting foam?

Following is a list of mechanical foam concentrates that are the most common types currently used by fire fighters today.

  • Aqueous Film Forming Foam (AFFF)
  • Alcohol Resistant (AR-AFFF)
  • Synthetic – medium or high expansion types (detergent)
  • Class “A” Foam Concentrate.
  • Wetting Agent.
  • Protein.
  • Film Forming Fluoroprotein (FFFP)

What is Class B firefighting foam?

Class B firefighting foams are commercial surfactant solutions that have been (and continue to be) stored and used for fire suppression, fire training, and flammable vapor suppression at military installations and civilian facilities and airports, well as at petroleum refineries and bulk storage facilities, and …

What is the difference between AFFF and AR AFFF?

OFAFFF AND AR-AFFF

AFFF and AR-AFFF consist of essentially the same ingredients. These typically include fluorosurfactants, hydrocarbon surfactants, solvents, inorganic salts, corrosion inhibitors, water; and in the case of AR- AFFF, a polymer which is typically a polysaccharide.

What does AFFF foam stand for?

Aqueous film forming foam (AFFF, or alcohol resistant AR-AFFF) is a highly effective foam used for fighting high-hazard flammable liquid fires. AFFF is usually created by combining foaming agents with fluorinated surfactants.

What’s the difference between Class A and Class B foam?

The true difference between a Class A foam and a Class B foam is that the Class B foam repels the carbons forming a film over the liquid, resulting in the suppression of the vapors, which is what is actually burning, while the Class A foam is penetrating the fuel.
