Operations Abnormalities & Plant Upset
- Recognise the early indicators that separate a normal process excursion from a developing plant upset.
- Apply a structured method to diagnose abnormal conditions in reactors, columns, exchangers and utilities.
- Prioritise operator actions during an upset to protect people, equipment and product quality.
- Use alarm management, trend data and process interlocks effectively under abnormal conditions.
- Conduct post-upset reviews that turn incidents into permanent operating improvements.
