Type 1 airlock is used for what purpose?

• A. Transmitting between two protected areas
• B. Goes from protected area to unprotected area
• C. Only used to exit the ship
• D. Used to enter the ship from space

Answer: (C)

Airlocks control passage between the ship’s controlled atmosphere and the outside environment, and a Type I airlock is designed specifically for one-way exit to space. It allows a crew member to depressurize the chamber and open the outer door so they can step out, while protecting the ship’s atmosphere from loss. Reentry or transfer between protected areas would use a different setup or procedure, so this type is described as being used for exiting the ship, not for entering from space.
