Firefighting foam solution is what percentage water?

Firefighting foam solution typically contains a significant proportion of water, which acts as a carrier for the foam concentrate and helps to suppress fire effectively. The correct understanding is that most firefighting foam solutions are composed of approximately 94% to 99.9% water. This high percentage is essential because water serves to cool the burning material and dilute flammable liquids while the foam creates a barrier that prevents oxygen from reaching the fire.

The focus on such a high water content is critical to the effectiveness of foam as it aids in achieving the desired foam blanket that smothers flames and prevents re-ignition. The low percentages of foam concentrate are responsible for creating the foam itself, which is epically critical for fire suppression in various fire scenarios. The presence of this vast amount of water ensures that the foam is able to maintain its effectiveness and stability when combating fires.
