Who primarily uses the damage control book (DC book) on a navy ship?

The Damage Control Book (DC book) is primarily used by the Repair Party Leader (RPL) on a navy ship. The RPL is responsible for leading the damage control efforts during emergencies, such as fires, flooding, or any situation that might compromise the ship's integrity. The DC book provides essential information, including procedures, checklists, and materials needed to respond effectively to damage control scenarios. This makes it an invaluable resource during emergency situations and for training personnel in damage control techniques.

While the Captain, Chief Engineer, and Damage Control Officer may also have important roles in managing damage control on a ship, they typically rely on the RPL to implement the immediate actions laid out in the DC book. The RPL's knowledge and command of the book ensure that the crew can perform coordinated and efficient damage control operations when necessary.
