| Title | Spill of Tc-99M Vial in Hot Lab |
| Event Description | [At 0930 MST on 12/24/18, a] Technologist went to screw the bottom of the pig on and had difficulty getting the bottom screwed on. The vial [containing approximately 272 mCi of Tc-99m] then slipped from the pig and the technologist's hands and dropped to the floor and broke. The technologist was wearing [Personal Protective Equipment] PPE in the form of gloves. Her shoes, clothing were removed and placed in a sealed bag to decay in the hot waste area. Initial reading from the sealed bag was 0.8 mR/hr. PPE was worn and the spill was covered with absorbent material. To prevent the spread of contamination movement of staff was limited. A witness was not contaminated during the incident as she was more than 10 feet from the hot lab and her personal survey results were 0.05 mR/hr which is equivalent to the background of the room. The contaminated personnel's skin readings post decon were 0.1 mR/hr at skin level on her leg.
The spill was sprayed with Radiacwash and the contaminated absorbent material was placed in a sealed bag, labeled with date and radioactivity and placed in the hot waste storage area to decay. The spill was contained within the nuclear medicine hot lab, a sign was posted to close the room and secure the area to prevent entry. Final survey and wipe tests were completed on 12/26/2018 at 1100 [MST]. The [Radiation Safety Officer] RSO was notified on 12/24/2018 at 0952 [MST]. The RSO talked to the Avera St. Luke's Director of Nuclear Medicine to ensure we are following the correct protocol. The RSO was notified on 12/26/2018 of the final survey and final wipe tests performed, and permission was given to return to work in the area. |
