Container storage facility

A container storage facility comprising:

• a container storage rack comprising a plurality of container placement sections on each of which a container is placeable;
• and
• an inactive gas supply apparatus configured to supply an inactive gas to each of the containers placed on the container placement sections,
• wherein the container storage rack is configured to be suspended from and supported by a ceiling, and the plurality of container placement sections are next to each other in a first direction extending in a horizontal direction, and,
• the container storage facility further comprises:
• a first sensor group comprising a plurality of oxygen concentration sensors at an overlapping height and next to each other in the first direction on a first side of the containers in a second direction orthogonal to the first direction as viewed in a vertical direction, the overlapping height being a position overlapping the containers placed on the container placement sections;
• a second sensor group comprising a plurality of oxygen concentration sensors at the overlapping height and next to each other in the first direction on a second side of the containers in the second direction;
• a third sensor group comprising a plurality of oxygen concentration sensors at a first predetermined height and next to each other in the first direction at positions further toward the first side in the second direction than the first sensor group, the first predetermined height being lower than the overlapping height;
• and
• a fourth sensor group comprising a plurality of oxygen concentration sensors at a second predetermined height and next to each other in the first direction at positions further toward the second side in the second direction than the second sensor group, the second predetermined height being lower than the overlapping height.
