Claim:
1. A storage facility comprising: a plurality of storage sections for storing containers; inactive gas supply passages for supplying inactive gas to respective ones of the plurality of storage sections; an inject portion provided to each of the plurality of storage sections for injecting inactive gas supplied from the corresponding inactive gas supply passage to an interior of the container stored in the corresponding storage section; a discharge portion provided to each of the plurality of storage sections for discharging gas within the corresponding container to outside the corresponding container when the inactive gas is injected from the inject portion to the interior of the container stored in the corresponding storage section; a plurality of supply amount adjusting devices, each of which is provided on an upstream side, in the corresponding inactive gas supply passage, of the corresponding inject portion of a corresponding one of the plurality of storage sections, for adjusting a supply amount of the inactive gas to the corresponding inject portion; a controller for monitoring a supply state of the inactive gas for the plurality of storage sections and for controlling the plurality of supply amount adjusting devices; wherein the controller is configured to monitor the supply state of the inactive gas for the plurality of storage sections by dividing the plurality of storage sections into a plurality of monitoring areas defined for each of groups of storage sections each of which consists of two or more storage sections with one located next to another, and to control the plurality of supply amount adjusting devices such that the supply state of the inactive gas supplied to the storage sections belonging to each of the plurality of monitoring areas satisfies a set restricting condition defined in advance; wherein the controller is configured: wherein, in the supply resume process, a part of or all of the storage sections are selected, as storage sections to which the supplying is to be resumed, from all the storage sections which can be the storage sections to which the supplying is to be resumed, such that the set restricting condition is satisfied in the monitoring area that the storage sections to which the supplying is to be resumed belong to if the supplying of the inactive gas is resumed to the storage sections to which the supplying is to be resumed; and wherein the controller is configured to manage elapsed time since storing of the corresponding container, for each of the plurality of storage sections, and to select, in the supply resume process, the storage sections to which the supplying is to be resumed from all the storage sections which can be the storage sections to which the supplying is to be resumed by giving priority to the storage sections for which the elapsed time is shorter.
