What is the raw form of foam concentrate referred to as?

The term "raw foam" refers to the initial, unprocessed state of foam concentrate before it has been mixed with water or other additives. This concentrate is typically a liquid that must be diluted to create the foam used in firefighting applications.

Foam concentrates consist of various chemical components designed to create a stable foam capable of smothering fires, particularly those involving flammable liquids. When firefighters prepare to use foam, they begin with this raw form, which is essential for producing effective firefighting foam. The process of mixing the concentrate with water activates the components, allowing them to expand and form the necessary foam blanket over a burning surface.

Understanding this terminology is crucial for fire service professionals, as it impacts how they prepare and use foam in firefighting tactics and strategies.
