| Title | Source Holder Stuck Shutter |
| Event Description | At approximately 0700 EDT, October 25, 2016, the RSO [Radiation Safety Officer] and Assistant RSO attempted to open the shutter on source holder 10071961 (Hemlock identifier), while preforming routine maintenance. The shutter operation failed, the shutter is stuck in the closed position. There were no exposures as a result of the failed shutter operation. Operating the shutter was part of a routine preventative maintenance plan. The process is currently shut down, therefore this incident caused no loss of production. The source holder is located on site. Hemlock Semiconductor Operations is in contact with Vega Americas, the manufacturer.
