Question 627 Deck Safety

The correct answer is D) They may be kept open if they can be automatically closed from the bridge. The reasoning behind this is that the doors from each deck to the stair tower must be capable of being closed from a central control station, typically the bridge, to prevent the spread of fire and smoke in case of an emergency. This requirement is outlined in regulations such as SOLAS (Safety of Life at Sea) and Coast Guard regulations. Having the ability to remotely close these doors from the bridge allows for quick and effective fire containment measures while the ship is underway. The other options are incorrect because A) the doors cannot be kept closed at all times as this would interfere with normal operations, B) the ventilation or air conditioning system status does not affect the door closure requirements, and C) while a Muster List can designate personnel to close the doors, this does not negate the need for automatic closure capabilities from the bridge.
