🔍 Key Concepts

• Purpose of an in-line foam proportioner in a fire hose system • How foam concentrate, water, and air combine to create finished foam • Operational advantages and limitations of portable proportioning devices

💭 Think About

• Think about what the in-line foam proportioner actually does to the mixture going to the nozzle: does it change the foam bubbles themselves, or the ingredients going into them? • Consider whether the main advantage of a portable in-line device is about foam quality, foam quantity, or hose handling and positioning. • Ask yourself: does this device primarily help the firefighter move around more easily, or is its main function related to getting the correct percentage of foam concentrate into the water stream?

✅ Before You Answer

• Verify how an in-line foam proportioner is connected in the hose line (between the pump and the nozzle) and what it meters into the stream. • Confirm whether the device is designed to control the foam concentrate ratio or to mechanically change bubble size or nozzle reach. • Check which option best matches the primary function of the equipment, not just a possible side effect.
