Which technique uses an eductor to introduce foam concentrate into a water stream?

The technique that employs an eductor to introduce foam concentrate into a water stream is induction. This process involves creating a vacuum within the eductor using the flow of the water, which allows foam concentrate to be drawn into the water stream. The goal is to mix the foam concentrate effectively with the water, creating a foam solution that can be used for fire suppression.

Induction is essential in firefighting as it allows for the efficient and effective application of foam, especially in fire scenarios involving flammable liquids. By using an eductor, the fire personnel can ensure that the foam concentrate is mixed properly and uniformly with water, which is crucial for achieving the desired firefighting effectiveness.

Understanding the induction process is vital for driver/operators as it highlights the importance of proper equipment use and operational techniques in managing fire incidents effectively.
