Which option is a correct expansion of HAZOP?

• A. Hazard Analysis and Operating Procedure
• B. Hazard and Operability Study
• C. Hazardous Automation and Planning
• D. Health and Occupational Performance

Answer: (B)

This question tests your knowledge of what HAZOP stands for in process safety. The expansion is Hazard and Operability Study, which reflects its aim to systematically examine a process for both hazards and potential operability problems that could affect safe, reliable operation. In HAZOP sessions, a team reviews the process step by step, often using guide words to explore deviations from the intended design and their causes and consequences. The goal is to identify scenarios that could lead to unsafe conditions, equipment damage, or process upsets, and then implement mitigations or safeguards. Other phrasings aren’t the standard expansion for HAZOP. For example, “Operating Procedure” describes a document outlining how to run equipment, not a structured study of hazards and operability. The remaining options blend terms that aren’t used in the established method, so they don’t match what HAZOP represents.
