Which type of door is designed for quick access and is water-tight?

The type of door designed for quick access and is water-tight is known as a quick acting door. These doors are specifically engineered to provide rapid opening and closing functionality, which is crucial in emergency situations where time is of the essence. The design often incorporates mechanisms that allow for swift operation, and their water-tight features make them ideal for locations where water ingress must be controlled, such as on ships or in industrial facilities.

Quick acting doors are built to ensure that they can be securely sealed during flooding or in situations where water intrusion is a risk, while also enabling personnel to enter or exit quickly. This combination of fast access and reliable water-tightness is essential for maintaining safety and operational efficiency in environments where containment is critical.

The other options, while they may serve specific purposes, do not encapsulate both the quick access and water-tight characteristics in the same manner as a quick acting door. For instance, hatch doors may not always provide the same levels of rapid accessibility or sealing, and power-driven doors often prioritize automation over urgency in access. Individual dogged doors are typically designed for secure closure rather than quick egress. Thus, quick acting doors stand out as the most suitable choice for the requirements stated in the question.
