🔍 Key Concepts

• Firefighting nozzles used on ships and how they look (straight stream, fog, foam) • How foam systems pick up and mix foam concentrate with water • The purpose of a long rigid tube with a pickup hose leading to a separate container

💭 Think About

• Look closely at the long tube and the small hose dropping down from it—what is that hose likely drawing from during a fire? • Which of the options would reasonably require a separate pickup from a drum or tank rather than just water from the fire main? • Think about which device is designed specifically to produce or apply a particular type of agent (fog vs foam) rather than just change the shape of a water stream.

✅ Before You Answer

• Identify whether the device in the drawing seems meant to handle only water or water plus another agent • Check which option names a device that would logically include a pickup hose into a concentrate container • Eliminate any options that don’t match the size, shape, and extra hose shown in the illustration
