Revision Date: 02-02-96 Title: Freeze Precaution Procedure References: Glossary of equipment identification (text #114) 814. Freeze Precaution Procedure: 1.0 Objective: 1.1 To take all water systems out of service or arrange the flows in such a manner as to prevent them from freezing during cold weather. 1.2 To monitor all water systems that might remain in service using the checklists provided. 2.0 Responsibility: 2.1 It is the responsibility of the operations supervisor and the senior operations specialist to ensure that this procedure is followed. 2.2 It is the responsibility of the senior operations specialist and the operations to follow this procedure and complete all associated checklists. specialist 3.0 Special Notations: 3.1 If the temperature is predicted to drop to 25 degrees f or less it will be necessary to put this procedure into effect. 3.2 All freeze protection valves should be monitored periodically using the checklists provided with the procedure. 3.3 Inform the plant insulator of any instrumentation or equipment which requires steam during cold weather in order for him to check the hot water tracing and the insulation on it. ' 3.4 Deluge guns should be considered as an option to wash off personnel if exposed to chemicals. Date Printed:April 18, 1998 Paper Copies Of This Document Are Uncontrolled & Not Subject To Update.
