Common Mistakes When Conducting a HAZOP and How to Avoid Them Arturo Trujillo, Walter S. Kessler, Robert Gaither

Subject(s): Diseño de procesos | HAZOP | Medio ambiente | Método HAZOP In: Chemical engineering Vol.122, No.12, 2015: páginas 54-58Abstract: An important part of ensuring the success of a HAZOP study is to understand the errors that can cause the team to lose focus. Since its inception in the 1960s and its first official publication in 1977, the Hazard and Operability Study (HAZOP) has become one of the most powerful tools for identifying process hazards in the chemical process industries (CPI). Utilizing systems that are qualitative or even simplified semi-quantitative, the HAZOP method has been increasingly used, not only as a tool for identifying process hazards, equipment deficiencies or failures and operability problems and assessing their risks, but also as a tool for prioritizing actions and recommendations for process-risk reduction. Reducing risk is especially important in ensuring the safety of the personnel who must work in the plant environment each day (Figure 1). The HAZOP methodology is a systematic team-based technique that can be used to effectively identify and analyze the risks of potentially hazardous process operations. It is the most widely used process hazard analysis (PHA) technique in numerous industries worldwide, including petrochemicals, pharmaceuticals, oil-and-gas and nuclear, and is used during the design stages of new processes or projects, for major process modifications and for periodic review of existing operations.
