🔍 Key Concepts

• Types of fire hose nozzles used on vessels (solid stream, fog, and combination/all-purpose) • What “combination” or “all-purpose” means in the context of fire streams • When fog vs. solid stream patterns are normally used in shipboard firefighting

💭 Think About

• Ask yourself: if a nozzle is called “combination” or “all‑purpose,” what capability would make it useful in many different fire situations? • Think about which answer choices describe more than one pattern that can be selected using the same nozzle, rather than being limited to a single pattern. • Consider which patterns are typically associated with cooling and protection of firefighters versus long-range water application.

✅ Before You Answer

• Verify which nozzle type can be adjusted to change the pattern of water leaving the nozzle. • Confirm whether foam production requires a special eductor or foam-making attachment, not just a standard combination nozzle. • Check which options mention only one pattern (solid or fog only) versus options that mention more than one selectable pattern.
