Title	Agreement State Report - Stuck Process Gauge Shutter
Event Description	The following is a synopsis of information received via E-mail: On 5/9/2018, the Radiation Safety Officer (RSO) for ExxonMobil Chemical Co. (EMCo) reported a device failure to the Louisiana Department of Environmental Quality. On 5/1/2018 during routine annual maintenance and preventive maintenance checks it was discovered that a level density gauge had a shutter stuck in the open position. The gauge was a Ronan Engineering Co. gauge, Model Number SA1-C5 loaded with 100 mCi Cs-137 (10/95). The device s/n is EE815. The source and source holder usually have one s/n for the whole device. A RONAN engineering sales and service company was contacted to fix the problem by repairing the gauge and the shutter to function properly. The gauge is installed on processes and does not pose a health and safety threat to the general public or the EMCo employees. The gauge will remain on the operational process until the repair is made to the device. A service order number was generated by EMCo for the device repair. The shutter was stuck in the open position due to the buildup of grime and corrosive material from the operational environment. This is considered an equipment failure for reporting requirements.
