How do inline eductors function with AFFF?

Inline eductors are devices used in firefighting systems that play a critical role in the effective application of Aqueous Film Forming Foam (AFFF). Their primary function is to mix AFFF concentrate with water to create an effective firefighting solution.

When water flows through the eductor, it creates a vacuum that draws the AFFF concentrate into the water stream. This mixing occurs in a controlled manner, ensuring a consistent and effective dilution of the foam concentrate. The properly mixed solution is essential for creating the desired foam characteristics necessary for extinguishing fires, especially those involving flammable liquids. This mixing capability is fundamental to the operational effectiveness of AFFF in firefighting scenarios, allowing for quick deployment and efficient fire suppression.

The other choices do not accurately describe the function of inline eductors. They do not cool the AFFF concentrate or pressurize the system, nor do they serve as storage containers for the AFFF. Their sole and vital function remains focused on the mixing process, making the correct answer integral to understanding how firefighting systems utilizing AFFF operate.
