This process involves identifying potential hazards, assessing their risks, and implementing measures to prevent or mitigate them. Hazard identification can be achieved through various methods such as process hazard analysis, safety audits, and incident investigations. Once hazards have been identified, risk assessment tools such as hazard and operability (HAZOP) studies, failure mode and effects analysis (FMEA), and fault tree analysis (FTA) can be used to evaluate the severity of the risks and prioritize preventive measures. Prevention measures can include engineering controls such as safety interlocks and pressure relief devices, administrative controls such as operating procedures and training, and personal protective equipment (PPE). Effective hazard identification and prevention require a comprehensive and systematic approach, and continuous improvement to ensure the safety of chemical processes.
