Which air lock type is used for entry into the ship?

• A. Type I
• B. Type II
• C. Type III
• D. Type IV

Answer: (A)

Type I air lock is the entry point used to bring personnel aboard from the outside into the ship. It’s designed to be the accessible path for ingress, providing a controlled transition between the external environment and the ship’s interior atmosphere. The two-door arrangement is key: it keeps one door closed while the other opens, helping to prevent uncontrolled air exchange, water, or contaminants from rushing into the ship and helps maintain the ship’s pressure and cleanliness. This entry-focused role is what sets Type I apart from other air locks, which are used for specialized tasks such as transfer of materials, decontamination, or handling hazardous conditions. So for simply entering the ship, the entry air lock—Type I—is the correct choice.
