Title	Process Gauge Shutter Stuck Open
Event Description	In the process of performing the inventory/shutter check it was reported on March 19, 2015 that our Kay Ray Model Number: 7050, Serial Number: 1405, 200 mCi, Cs-137 gauge located on 4B DTU (Deslime Thickener U/Flow) in the deslime basement had a broken handle on the shutter mechanism, rendering the shutter non-operable. Work order (1545064) was entered into Ellipse. It was determined that the area in which the gauge is located does not create an exposure hazard. The plant process requires the shutter to remain in the open position during normal operation and does not create a hazard to individuals, the course of action will be to remove and replace the gauge at the first opportunity. Once the gauge is removed, it will be placed and locked in the cage located in the warehouse. The gauge will be placed on top of the required amount of lead to remove any potential exposure hazard; surveys will be performed to confirm personnel safety.
