Task Summary:
1. Inform production operations of the planned work area of facility where control valves are to have stem packing inspected.
1. Inform production operations of the planned work area of facility where control valves are to have stem packing inspected.
2. For each control valve stem packing being inspected, spray snoop to stem packing sealing area to determine if any leaking is occurring. Some very minor leaking (fugitive emissions magnitude) may be occurring, which is not unusual.
