Improve Process Safety with Near - Miss Analysis
نویسندگان
چکیده
Automated control and safety systems that help a plant return to normal operating conditions when abnormal events occur are prevalent in modern chemical plants. The databases associated with these systems contain a wealth of information about near-miss occurrences that, if subjected to frequent statistical analysis, can provide metrics to predict and ideally prevent accidents. Such analysis is referred to as dynamic risk analysis. This article introduces the concept of dynamic risk analysis (DRA) based on alarm databases. It provides a general overview of what this is, how it can be used in chemical processing to improve safety, and challenges that must be addressed over the next 5–10 years. It also highlights current research in this area and offers perspective on methodologies most likely to succeed.

Despite decades of research on organizational disasters and their prevention, disasters remain all too common-place. Scholars across a wide range of disciplines agree that the one of the most viable approaches to reducing their occurrence is to observe near-misses-situations where a bad outcome could have occurred except for the fortunate intervention of chance--and use these events to identify...
