| ENS 46536 | 19 September 2010 01:30:00 | Agreement State | Agreement State Report Involving an Exit Tritium Sign Destroyed in a Facility Fire | The following information was received by facsimile: The RPS (North Carolina Radiation Protection Section) received a voice message on 1-6-2011 from the FMC Lithium RSO (Radiation Safety Officer). The RSO wanted RPS to contact him concerning removing an Exit Sign from his current inventory of sources. (RPS) was able to get in touch with the RSO on Wednesday, January 12, 2011 and the RSO stated on the phone than he needed to remove the Exit Sign because there was a fire at the facility on September 18, 2010 that shut down the facility for two weeks and damage was around $500,000. RPS explained to the RSO that he should have responded and reported the incident/fire immediately to our office. (RPS) received a call back from the RSO for FMC Lithium concerning which Exit Sign was affected by fire on September 18, 2010. The General License Number: 036-2384-0G has 6 Cs-137 gauges that are active and one Cs-137 gauge in storage. Also, they have 22 Tritium exit lights in service on and before the fire on September 18, 2010. The reason the RSO reported the Exit Sign on 1-12-2011 was he was going to order a replacement for the one that was destroyed in the fire and he was getting ready to perform a Radiation Training Session for their employees. The source that was destroyed was: Manufacturer: Shield, Model: SLX-60, Serial Number: 10-21664, Source: H-3, Activity: 0.230 mCi ea., Location: SO Building 1st floor. Installed: Aug/2010" North Carolina Event: 11-02
The state called to clarify that the activity level is 6.21 Curies H-3 vice 0.230 mCuries, and the manufacturers full name is Shield/Isolite vice Shield as reported above for the exit sign which was destroyed. Notified R1DO(Jackson) and FSME(Villamar). 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.
