Synthetic foam concentrate is commonly known as what?

1. AFFF

2. FFLP

3. Class A

4. Class B

The correct answer is: AFFF

Synthetic foam concentrate is commonly known as AFFF, which stands for Aqueous Film-Forming Foam. This type of foam concentrate is widely used in fire suppression, particularly for flammable liquid fires, such as those involving petroleum products. AFFF works by creating a film on the surface of the burning liquid, which helps to suppress vapors and cool the fire, thereby preventing re-ignition. The other options do refer to different types of firefighting agents or classifications. FFLP, or Film-Forming Fluoroprotein, is a type of foam concentrate but is not as commonly recognized as AFFF. Class A refers to extinguishing agents suitable for ordinary combustibles like wood and paper, while Class B pertains to those suitable for flammable liquids and gases. However, AFFF specifically denotes synthetic foam concentrate, making it the most accurate choice for the question.
