| Title | Notification of a Lost Tritium Exit Sign |
| Event Description | During an annual audit on 3/28/2018, the licensee determined that a self luminous exit sign was missing. Through interviews the licensee determined that an employee had removed the sign during a safety walkdown, because it did not appear to be working, and likely disposed of in the trash. Through a records review the licensee determined the safety walkdown was most likely on 11/1/2017.
The licensee information on the self luminous exit sign is that it was a Isolite model SLX60, serial number Y60813, manufactured in 11/2008 with an activity of 7.4 curies of H(3). The licensee continues to investigate this event and has counseled the employee to follow the procedures for these signs. The licensee is planning to put out a general communication on these signs, and for the eventual removal of all the self luminous exit signs. The licensee is preparing a written report. 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.
