Which term describes the completed product after air is introduced into the foam solution?

• A. Foam
• B. Foam concentrate
• C. Finished foam
• D. Fluoroprotein foam

Answer: (C)

The idea is that once air is mixed into the foam solution, it becomes an aerated, bubble-rich blanket used for firefighting. This completed, dischargeable product is called finished foam. It distinguishes the final foam you apply from the raw materials and intermediate terms: foam concentrate is the chemical before it’s mixed with water, and foam (in some contexts) can be vague or refer to the liquid or the finished product loosely. Fluoroprotein foam refers to a specific type of foam concentrate, not the finished product itself.
