Floor 1 of the Heavy Containment zone stores hard to contain SCPs. They are comparatively smaller and less dangerous than ones found on Floor 2, although that isn't to say they are still without danger. The area has two checkpoints to the Light Containment Zone, along with an elevator to Gate B. It also has backup power generators for the facility, an elevator to Storage Area 6, an elevator to the Omega Warhead Silo, staff dormitories, an Armory, and a maintenance area.
