General Collection Zones


Layout of Zones


After all red high priority items are collected, personnel must focus on retrieving any items not yet recovered. Since this will be a large percentage of the facility, it is recommended that remaining items are collected using a zone system. The team divided each shelf (one side of one aisle) into 9 zones (Figure 8.1). After a disaster, trays will be placed into boxes and loaded onto a freezer truck for transportation to another storage facility by BMS CAT (a contracted recovery company). Zone size was based on the average number of trays a typical freezer truck can hold, which BMS CAT has estimated as 1500 trays (using an average of 1.2 ft3 per box). Each zone contains between 86-107 locations, with a 14 tray average at each location, each zone contains between 1204-1500 individual trays.

The shelves’ bottom three zones are all under the 11th row so that they may be retrieved manually with a moveable stair ladder. In addition, the top of these bottom zones were placed under a vertical metal bar that runs the length of each shelf, making the boundaries easily identifiable.

Maintaining Intellectual Control   


General collection items will be collected one zone at a time, with unloading beginning at the bottom left corner of the zone. This first location will be unloaded, and all 14 trays moved together to where they will be boxed. These 14 boxes will be marked with a visual identification, identifying them as the first location in the zone. The next location (same ladder, one row up) will then be collected and all 14 trays kept together, once boxed, they will receive different identification and scanned out by the LAS before being loaded onto the truck. This will allow the facility to know which trays and books have been removed from the facility for restoration. This process will be continued in the same manner until the truck has been filled. Once transported to the storage facility, the boxes will be removed in reverse order, and the zone can be recreated flat along the floor space (as if the shelf had been rotated 90 degrees to lie along the floor).

Identification at each zone will consist of a color and zone number to distinguish both the location within the zone and the zone. After each tray is boxed for transport, the box will be labeled. Though tags may be purchased before any disaster, they cannot be applied beforehand because they will be affixed to the boxes (to be purchased after a disaster) and not to the tray themselves, where they would not be able to be seen during transport.
