HAZOP stands for Hazard and Operability Study. Which of the following is a correct expansion?

• A. Hazard and Operability Study
• B. Hazard and Operation Scheduling
• C. Hazardous Operations Study
• D. Health and Safety Optimization Plan

Answer: (A)

Hazard and Operability Study is the established name for this safety review method. HAZOP is a structured technique used in process industries to identify potential hazards and operability problems that could arise during normal or abnormal operation, so the expansion should reflect both hazard identification and how the process might operate or fail to operate as intended. The other phrases don’t reflect the standard terminology used in process safety: they imply scheduling, different wording of operations, or a generic health-and-safety plan, none of which capture the specific focus of this method.
