Title	Fixed Gauge Shutter Stuck in the on Position
Event Description	The following information was provided by the Washington State Office of Radiation Protection via email: During the semi-annual routine shutter tests on a fixed gauge, the gauge was found to be stuck in the 'ON' position. This malfunction did not pose any additional risk to personnel in the 'ON' position; it only inhibited the ability to lock the gauge in the 'OFF' position for maintenance. The gauge manufacturer was contacted, and a service engineer was able to move the source tube assembly to the 'OFF' position by applying lubricant to the handle rod and gently twisting and pulling on it. This event appears to have occurred due to a lack of lubricant on the handle rod, or from the dust conditions that the gauge is located in, resulting in the source tube assembly becoming stuck inside the source housing. Going forward, a few drops of lubricant will be added during the semi-annual shutter checks to prevent the source tube assembly from becoming stuck again. There were no personnel overexposures due to this event. Device/Source Details: VEGA Americas, Inc., model number: HLG-2, serial number: 13570676, containing a 2 Ci (original activity) Cs-137 source. Reference Document Number: WA-23-013.
