This is the first paper to apply a combination of HAZOP and Risk Consequence Matrix plus Cross Impact Analysis (CIA) and Interpretative Structural Modeling (ISM) methods for analyzing complex cascading effects in Operational Risk Management in an industrial environment. This combination of methods allow obtain more information than using HAZOP and Risk Consequence Matrix because upgrades the in...

Chemical hazards are one of the most dangerous hazards occurring in any industries that uses them. Several devastating effects like explosion, environmental pollution, asphyxiation, acid burns, and skin disorders, chronic and acute conditions of several diseases might occur due to the leakage of the poisonous chemicals. This project deals in the control of the chemical hazards in a Stainless St...

The number of bioprocesses for the circular economy organic waste has grown in recent years. Implementation new processes and technologies should consider occupational health safety issues from initial design stages. Among process hazards analysis techniques, HAZard OPerability (HAZOP) methodology is widely used studying both process’s their operability problems, by exploring effects any deviat...

We give a model for hazard analysis of user-interaction based on HAZOP. We consider the role of formal speciication and user-interface design in such a hazard analysis. Formal speciications can be used to describe tasks, while the user-interface design describes executions to eeect tasks. We illustrate the user-interface hazard analysis process by considering execution errors for a \data-link" ...

In this paper we present a HAZOP Assistant based on D-higraphs, a functional modeling technique that gathers functional and structural information of the process under study. The Assistant and the methodology are presented and applied to an industrial case: H2S absorption and DEA regeneration. Its results are compared with other existing techniques showing that the Assistant fills the gaps and ...
