risk assessment and management techniques are used in industrial activities to reduce accidents by applying preventive and protective methods. in this article a preventive approach called hazard and operability study (hazop) was used. the application of hazop, a process hazard identification and control method, has been demonstrated in the fatty acid unit of golnar oil company, northwest of teh...

HAZOP is a widely-used technique for identifying potential hazards in process plants. However, the application of the technique is very repetitive and time consuming. One way to overcome this bottleneck is to develop automated hazard identification systems that emulate the HAZOP technique. Much of the research on automated hazard identification so far has concentrated on continuous plants by co...

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...
