Question 570 Deck Safety

The correct answer is C) close all ventilation to the quarters if possible. In the event of a fire on board a vessel, the primary objective is to contain the fire and prevent it from spreading. Closing all ventilation to the affected area helps starve the fire of oxygen, which is a critical component for combustion. This measure is in line with standard firefighting procedures and maritime safety regulations. The other options are not recommended. Ventilating the quarters (A) could inadvertently provide more oxygen to the fire, causing it to grow. Attempting to put out the fire yourself (B) before sounding the alarm may delay the activation of the vessel's emergency response plan. Preparing to abandon ship (D) should only be considered as a last resort, after all efforts to contain the fire have been exhausted.
