The NAM standard airlock doors most resemble old style warship bulkheads that are heavy, operate on hinges, and have a manual locking system requiring some strength to seal.

The ship’s airlocks are made out of large, heavy doors that open towards the high pressure side of the ship meaning in the event of accidental opening the ship’s own atmosphere will force the doors closed. Each is white and lined with a padded gray material that doubles as an electronic display. A long leaver extends downward from a protrusion in the center of the door. When rotated to point upward the door is manually locked, when rotated downward the door is manually unlocked. The doors have an electronic locking system that is separate from this system and is disabled when the door power is disabled. A strip of smart material is wrapped vertically around the airlock. If both sides of the airlock are uninhabitable the strip turns a glossy black. If one side is uninhabitable it turns red. If one side has breathable atmosphere but a harmful toxin the strip will turn yellow while if both sides contain livable atmosphere the strip turns green.
