A new semi-automated HAZID method for more comprehensive identification of hazardous scenarios

Despite the substantial development of HAZID methods, traditional HAZID tools still need further development because of their weaknesses in identifying possible hazards. Despite many measures, still continual catastrophic events occur, even after reviewing potential scenarios with HAZID tools. Therefore, it is evident that unintended incidents that occasionally occur in the process industries, in order to prevent, require more enhanced HAZID tools. With this new HAZID methodology, this study seeks to identify possible scenarios with a semi-automated system approach. Based on the two traditional HAZID tools, Hazard Operability (HAZOP) Study and Failure Modes, Effects, and Criticality Analysis (FMECA), the new method will minimize the limitations of each method. Additionally, rather than depending on the HAZID tools to achieve the connectivity information of the process system, this study will consider obtaining in prepopulated sheets connection of linked components by means of new advanced technologies before applying HAZID tools. Next, this method can be integrated with proper guidelines regarding process safer design and hazard analysis. To examine its usefulness, the method will be applied to a case study.
