CAFS stands for which foam system?

• A. Cold Air Foam System
• B. Compressed Air Foam System
• C. Contained Air Foam Setup
• D. Compact Air Fixed System

Answer: (B)

CAFS stands for Compressed Air Foam System. The key idea is that foam concentrate is mixed with air under pressure to create a foam solution with expanded bubbles. This foam blankets the fuel more effectively, provides better cooling, and often allows for using less water while achieving the same or better knockdown. The “Compressed Air” part is what gives CAFS its distinctive texture and reach, enabling finer bubbles and a more stable foam blanket. The other options don’t reflect the standard terminology used for this foam delivery method, so they aren’t correct descriptions of CAFS.
