🔍 Key Concepts

• How AFFF extinguishes flammable liquid (Class B) fires • Relationship between foam blanket, water content, and vapor suppression • Compatibility of AFFF with other extinguishing agents like dry chemical

💭 Think About

• Ask yourself: What is the MAIN extinguishing action of AFFF on flammable liquid fires—does it smother, cool, or stop vapors? • Think about whether AFFF foam is usually mixed with sea water, fresh water, or if it’s limited to one type only. • Consider what happens to a foam blanket if it is physically disturbed—does agitation ever break up foam layers in real firefighting situations?

✅ Before You Answer

• Verify how AFFF actually stops a fuel from burning: does it work by forming an aqueous (water) film over the fuel surface? • Check if standard marine fire-fighting doctrine allows AFFF to be used together with dry chemical agents. • Think about the word “cannot” in the choices—are the limitations described there consistent with how foam behaves in practice?

Question 1 of 20

Which of the following statements is true concerning Aqueous Film Forming Foam (AFFF)?

The agent cannot be used in conjunction with dry chemicals.

AFFF can only be produced from fresh water.

Because AFFF works through surface tension, it cannot be broken up if it is agitated.

AFFF controls the vaporization of flammable liquids by means of a water film.
