What does compressed air foam (CAF) typically adhere to?

Compressed air foam (CAF) is specifically designed to adhere to various surfaces during firefighting operations. Its formulation includes a mixture of water, compressed air, and certain foam additives, which enhance its ability to coat and cling to surfaces.

In the context of firefighting, CAF can effectively stick to building surfaces, which is crucial for suppressing fires in structures. When applied, the foam effectively blankets the surface, creating a protective barrier that helps prevent fire spread and reduces heat release rates. This adhesion to building surfaces is vital in maintaining firefighting efforts, as it allows the foam to stay in place longer than water alone, which can simply run off.

While CAF can interact with other surfaces, such as metal or vegetation, its primary function and effectiveness is most evident in its adherence to building surfaces during firefighting operations. This capability is what makes CAF a valuable tool in fire suppression tactics.
