Question 545 Deck Safety

The correct answer is B) All watertight doors in the vicinity of the drill shall be operated. During a fire and boat drill on a vessel, the focus is on testing the crew's preparedness and the vessel's safety equipment. Specifically, operating the watertight doors in the vicinity ensures that the crew is familiar with their location and functionality, which is crucial in containing the spread of fire or water in an emergency situation. The other options, while important, are not the primary focus of a fire and boat drill.
