Quarantine Access A is a small hallway in the Phazon Mines with 4 Mega Turrets guarding the center. There is a small tunnel underneath the hallway which is accessible through Samus's Morph Ball. This allows Samus to roll by the turrets and reach the other side. On the side closest to the Metroid Quarantine A, there is a scannable panel near the door which disables the turrets. Numerous Xenome Containment Units holding remains of what may be Elite Pirates can also be seen in here, as well as metal crates.
