Question 61 ONC05 - Master or Mate of LT 200 GRT

The Correct Answer is C **Explanation of Correct Answer (C):** Option C, "All watertight doors in the vicinity of the drill shall be operated," describes a mandatory and crucial component of any effective fire and boat drill, as required by international maritime regulations (specifically SOLAS – Safety of Life at Sea). The purpose of the drill is not just to practice mustering, but also to ensure that crew members are familiar with and can operate emergency equipment and closures. Operating watertight doors confirms they are functional, and that the crew knows how to close them quickly in an emergency (such as collision or flooding) to maintain the vessel's subdivision integrity. **Explanation of Incorrect Answers:** * **A) Fire pumps shall be started and all exterior outlets opened.** While fire pumps must be tested, the regulation requires that a *full flow of water* is delivered to some hoses (to ensure the system works), but it does not mandate that *all* exterior outlets be opened simultaneously during a standard drill. Doing so would be highly disruptive and potentially hazardous to those on deck. * **B) All lifeboat equipment shall be examined.** While lifeboat equipment must be inspected regularly (weekly/monthly checks), the *drill* itself focuses primarily on the crew's ability to muster, prepare, launch, and operate the survival craft, and confirm the equipment is present and properly stowed. A full, detailed examination of *all* internal equipment (e.g., rations, flares, first aid kit) is a maintenance/inspection task separate from the functional requirements of the fire and boat drill itself. * **D) All of the above.** Since options A and B are not strictly mandated requirements for the execution of every fire and boat drill, this option is incorrect.
