Who should be immediately notified when alarms go off in the Deck House?

When alarms go off in the Deck House, the Officer of the Deck (OOD) should be immediately notified because the OOD has overall responsibility for the operational status of the ship and the safety of personnel on board. The OOD is the one who maintains situational awareness, coordinates responses to emergencies, and ensures adherence to safety protocols. Timely notification enables the OOD to assess the situation, communicate effectively with other crew members, and take appropriate actions to address the alarm situation.

Other personnel, such as the Executive Officer, Deck Supervisor, or Medical Officer, may need to be involved later in the process; however, it is the OOD who is in the best position to make initial assessments and decisions regarding the response to the alarm, ensuring a coordinated and efficient handling of the situation.
