Development of Incident Investigation System for Process Safety Management in Process Industries

Recurrence of past major accidents, injuries and fatalities are often reported in process industries which resulted in significant losses in terms of lives and property. Although proper incident investigation has been performed to identify the causes of an accident, but the failure to perform investigation thoroughly by identifying the root cause of an incident causes lack of relevant investigation findings and gives opportunity for incident to reoccur. The objective of this project is to develop an incident investigation root cause analysis model, Tripod Beta, to help industries investigation team to thoroughly investigate and identify the root cause of an incident thus confirming the necessity of a root cause analysis in performing incident investigation. The scope of this project involves development of the incident investigation system framework based on OSHA PSM, perform case study based on process plant investigation report in order to develop the root cause model, and establishing a data storing and sharing system for better communication of incident inside organization. The result of the constructed tripod beta model will help confirming the necessity of a root cause model, which is a powerful tool in order to identify the root cause of an incident, thus giving industry a more reliable preventive action measure to avoid accident recurrence. This will result in cost saving in terms of reduce compensation claim and property losses from an accident. and also serves as a reference precaution measures for other similar processing unit.
