In response to a fire on the main deck or in the accommodation spaces, who would ordinarily report immediately to the scene of the fire and act as second in command of the fire team led by the chief mate?

Correct Answer: Option B — First Assistant Engineer

The First Assistant Engineer is the primary technical officer responsible for the engine department's emergency response. In the event of a fire in accommodation or on deck, they report to the scene to assist the Chief Mate, providing technical expertise regarding fire main pressure, ventilation control, and system isolation.
