“Hunting for Hazards”
Leaving no stone unturned, no nook or corner unchecked, till we identify all hazards that threaten our installation or personnel or public
- HAZOP stands for Hazard and Operability study. HAZOP uses a set of process parameters and guide words to develop the deviations from the design intent. It then relies on the team members to identify credible causes for the deviation, followed by consequences emanating from the deviation and then assess the adequacy of the safeguards. If the safeguards are not adequate, it allows for recommendations to be made. In recent years, the industry is moving towards quantification; in this direction, the high criticality scenarios are developed further in a LOPA (layers of protection analysis) study to do a semi-qualitative assessment of the protection layers and provide any safety instrumented system that may need to be implemented.
