What should be done with a dorrr, hatch, or scuttle when not in use?

When a door, hatch, or scuttle is not in use, it must be closed unless there is an operational requirement for it to remain open. Closing these entries is a critical safety practice aboard aircraft carriers to prevent accidental entries, reduce the risk of fire from explosive materials, and enhance overall ship integrity. Keeping these openings closed also helps to maintain proper compartmentalization, which is vital for controlling potential fire or flooding incidents and protecting personnel from hazards such as falling objects or unexpected hazards.

Maintaining closed doors and hatches aligns with the safety protocols established for handling explosives and hazardous materials on board, ensuring that the ship meets its operational and safety standards. Therefore, closing them when not in use is essential for keeping the environment safe for all personnel and preventing unauthorized access to potentially dangerous areas.
