The following historical information was received from the State of
Tennessee via email:
During a routine inspection, it was discovered through review of Toxco Radiological Occurrence Reports that Toxco had an event on June 17, 2013. In the Building A Supercompactor Room, a 55-gallon drum exploded due to an exothermic reaction. The cause was suspected to be the inadvertent packing of nitro-cellulous filters being placed in a waste drum of 3.7 mCi of I-125 contaminated personal protective equipment from Boston Heart Laboratory. The compactor was secured and no indication of radioactive material was discovered in the vicinity beyond the compaction cell. All personnel passed through a personnel contamination monitor without incident. The licensee performed a root-cause analysis determining that Boston Heart Laboratory had packed the nitro-cellulous filters into the waste containers. The licensee isolated two additional 55-gallon drums for return to Boston Heart Laboratory.
