The general license section of the [Colorado Department of Public Health and Environment] Radioactive Materials Program sent out annual notifications requesting response regarding tritium exit signs reported in use at locations given by the manufacturer. Upon an audit of the annual mailing for non-responders, Cintas First Aid & Safety was contacted. The contact at Cintas Fire & Safety explained they had moved from the event location and provided a new address. According to the contact since 6 years have passed and due to the move to a new location records from 2010 are no longer available. The contact was not able to confirm if the tritium exit sign was installed in the building or sold to one of their companies they provide service to.
Isolite was contacted to obtain information from a purchase order number provided on the manufacturer report. According to Isolite, the tritium exit sign was ordered through Grainger (PO# 4604805115). No information was provided showing any other address other than the event location.

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than
IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. 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.
