What is a key advantage of using compressed air foam systems (CAFS)?

A significant advantage of using compressed air foam systems (CAFS) is their ability to achieve higher expansion ratios compared to standard foam. This increased expansion allows CAFS to generate a larger volume of foam from a smaller amount of liquid concentrate, creating a lightweight and mobile foam blanket. The enhanced expansion ratio contributes to improved coverage and enhanced effectiveness in extinguishing fires.

Additionally, the bubbles formed are more stable and can effectively adhere to surfaces, providing better insulation against heat and preventing re-ignition. The foam's ability to expand also helps fill complex spaces in a fire's environment, leading to more efficient fire suppression compared to traditional foam methods. This characteristic makes CAFS particularly advantageous in firefighting, as it enhances performance while optimizing the use of resources.
