Who must be notified in the event of a loss of fire main pressure?

In the event of a loss of fire main pressure, it is essential to notify the Officer of the Deck (OOD) and the Damage Control Center (DCC). The OOD is responsible for the overall management of the ship's operations and must be informed of any significant incidents that could affect the vessel's safety and combat readiness. The DCC, on the other hand, plays a critical role in coordinating damage control efforts, which includes addressing issues related to firefighting systems. Loss of fire main pressure can impede firefighting capabilities, making it paramount for both the OOD and DCC to be alerted and respond accordingly to take corrective actions and ensure the safety of the crew and ship.
