What does CAFS stand for?

• A. Combination Air Foam System
• B. Central Air Foam Supply
• C. Compressed Air Foam System
• D. Controlled Air Foam Solution

Answer: (C)

CAFS describes a firefighting approach where foam concentrate is mixed with air under pressure to produce a stable foam blanket. The key idea is that the compressed air expands the foam solution, allowing it to cling to surfaces, penetrate fuels, and provide rapid knockdown and cooling with less water than traditional methods. This enhanced foam blanket helps suppress flames more efficiently and with greater reach, which is why the term emphasizes both the foam and the method of producing it. The standard term used in training and practice is Compressed Air Foam System, reflecting the combination of foam chemistry and air-driven delivery. The other options aren’t recognized terms for this concept.
