ENS 4302721 April 2006 06:00:00Agreement StateAgreement State Report - Missing Self-Illuminating Exit SignsThe State provided the following information via facsimile: Late last winter and early this spring the general licensee hired a consulting firm to do an inventory of the self-illuminating exit signs in Nebraska. They used the inventory lists of exit signs from the Radiation Control Program in Nebraska and lists from the manufacturers of Isolite (Safety Light) and SRB Technologies to make a comprehensive list of exit signs assigned to Nebraska Licensees. This comprehensive list was taken to each store and compared to the signs that were installed. They made more than one trip to the stores to make sure they had an accurate inventory. They discovered that some signs had been returned to the manufacturer and some signs installed in other Wal-Mart stores in and out of Nebraska. The consultants found 2 missing signs at this location. To help with the inventory in the future, the licensee (1) put a sticker on each tritium exit sign with the 'Item Number' assigned by the State of Nebraska, (2) The sign location was marked on a drawing of the store's floor plan, and (3) The inventory information was compiled and stored in a database. The licensee has discontinued having self illuminating signs installed in their stores in Nebraska. They are also considering replacing the signs with non radioactive material exit signs as they remodel stores in the future. They will continue to do inventories of stores in other states and may find some of the missing signs. The consultants discovered that some contractors took signs from one store to another when they had extra signs left after a construction project. The licensee was unable to determine if the missing signs were installed in this location and then removed during previous remodeling or if the signs were never installed at this location.

Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
