What is the main function of an inline eductor in fire suppression?

• A. To extinguish flames directly
• B. To mix AFFF
• C. To store water
• D. To increase pressure

Answer: (B)

An inline eductor is primarily used in fire suppression systems to mix foam concentrate, such as Aqueous Film-Forming Foam (AFFF), with water. This mixing process is essential as it creates the foam solution that is then used to extinguish fires, particularly those involving flammable liquids. The eductor operates by using the flow of water through a venturi passage to create a vacuum that draws in the foam concentrate, ensuring a uniform mixture is produced before it is discharged. In fire suppression applications, ensuring the right mixture of foam and water is crucial for effective fire control and extinguishment. The foam works by forming a barrier between the fuel and the fire, suppressing vapors and cooling the flames. Therefore, the main function of the inline eductor is critical for the readiness and effectiveness of a fire suppression system, making it an indispensable component in combating certain types of fires.
