Which device introduces foam concentrate into the water stream to form foam solution?

• A. Foam concentrate
• B. Foam proportioner
• C. Foam solution
• D. Class A foam

Answer: (B)

The device that introduces foam concentrate into the water stream to form the foam solution is the foam proportioner. It sits in the water line and uses suction or venturi action to draw the concentrate into the moving water at a calibrated ratio, producing the foam solution that reaches the nozzle for application. Foam concentrate is the chemical used to create foam; foam solution is the resulting mixture after mixing; Class A foam refers to a type of foam concentrate, not a device. So the proportioner is the component responsible for blending the concentrate with water to make the foam solution.
