What does the acronym CAFS stand for?

Compressed air foam system
Cylindrical air foam system
Compressed aerosol foam system
Compacted air foam solution

The correct answer is: Compressed air foam system

The acronym CAFS stands for Compressed Air Foam System. This technology is widely used in firefighting to enhance the effectiveness of water and foam agents when combating fires. By mixing air with foam concentrate and water, CAFS produces a high-quality foam that is lightweight, stable, and provides excellent coverage over burning materials. This system helps to smother the flames, preventing re-ignition, and can be used on a variety of fire types, including Class A (ordinary combustibles) and Class B (flammable liquids) fires. Understanding this term and its application is crucial for firefighters, as it reflects advancements in fire suppression techniques that improve safety and efficiency. Other options listed do not accurately represent the common terminology or methods used in firefighting.
