In the induction method of foam proportioning, what is the main purpose of the educator?

The main purpose of the educator in the induction method of foam proportioning is to introduce foam concentrate into the water. This system uses water flow to create a vacuum that draws foam concentrate from a container into the water stream, ensuring that the foam is properly mixed and proportioned before it is applied to a fire. The educator effectively combines these two vital components—the water and foam concentrate—allowing for efficient foam application. This process is essential for creating a foam that can suppress fire by suffocating it and creating a barrier to inhibit oxygen from reaching the burning material.
