Watertight Door
A watertight door is a door designed to prevent the passage of water from one compartment to another during flooding or other emergency situations. These doors are commonly used on ships and submarines to compartmentalize the vessel and limit the spread of flooding in the event of a breach in the hull. Watertight doors are typically made of steel and have a rubber gasket around the perimeter to create a watertight seal when the door is closed. They are operated by a wheel or lever mechanism that compresses the gasket against the door frame. Watertight doors are an important safety feature on ships and submarines, as they help to prevent sinking and loss of life in emergency situations.
