🔍 Key Concepts

• Fire main system components on a ship, especially devices installed in the hose line before the nozzle • The purpose of a strainer or screen in a fire-fighting water system • Differences between nozzles (which shape the water pattern) and inline devices that protect the system

💭 Think About

• Look closely at the label at the top of the illustration and think about what that type of device usually does in a piping system. • Does the cut‑away show any moving parts or passages that would create spray patterns or foam, or does it mainly show perforations for water to pass through? • Which answer choices describe a function normally done at the nozzle tip versus something done upstream in the hose or piping?

✅ Before You Answer

• Confirm what a self‑cleaning strainer is used for in general piping or fire main systems. • Decide which choice refers to protecting hoses and nozzles versus actually forming a spray or foam pattern. • Make sure the function you pick matches a device with perforated internal surfaces like the one shown, rather than a nozzle outlet.
