• A. True
• B. False
• C. Sometimes
• D. Not allowed

Answer: (A)

When using a foam eductor that isn’t at the pump panel, a person should be stationed at the eductor to supervise the foam concentrate and the eductor itself. The eductor relies on the main water flow to aspirate foam concentrate, and you typically can’t see the eductor’s suction, priming, or the concentrate level from the pump panel. A dedicated observer at the eductor can confirm the concentrate is being drawn properly, watch for loss of prime or air in the line, and verify that the concentrate valve and line are supplying foam at the correct rate. They also monitor the foam supply level to prevent running dry, which would stop foam production and disrupt the mix. Having this on-site supervision helps ensure the proper foam proportioning, reliable operation, and a safer, more effective foam application on scene.
