Question 67 ONC05 - Master or Mate of LT 200 GRT

The Correct Answer is D Muster lists are legally required safety documents onboard vessels. Their primary purpose is to clearly define the duties of every person during an emergency (such as fire or abandon ship) and show where their emergency stations are located. To ensure maximum visibility and immediate access for all personnel, the lists must be posted in various prominent locations throughout the ship. **Why option D ("All of the above") is correct:** Maritime safety regulations (specifically SOLAS Chapter III, Regulation 8, concerning Muster Lists and Emergency Instructions) mandate that muster lists must be exhibited in several conspicuous places around the ship, including, but not limited to: * **Engine room (A):** The personnel working here need immediate access to their emergency duties and routes without having to travel far. * **Navigating bridge (B):** This is the central command station during an emergency, and the officers managing the situation need the lists readily available for reference. * **Crew's accommodation spaces (C):** Posting the lists where the crew lives ensures they can easily review their duties regularly and can quickly check them upon waking or during off-watch hours. Since all three listed locations are appropriate and typically required posting locations for the muster list, "All of the above" is the correct choice. **Why the other options are incorrect (as standalone answers):** * **A) In the engine room:** While correct, posting the list only here fails to inform the crew in accommodation areas or the officers on the bridge, rendering the list ineffective for the majority of the ship's personnel. * **B) On the navigating bridge:** While correct, posting the list only here fails to inform personnel working deep within the ship or those in their cabins, limiting its accessibility. * **C) In crew's accommodation spaces:** While correct, posting the list only here fails to ensure immediate access for personnel who may be working in the engine room or on the bridge when an emergency occurs.
