What is a common purpose of Process Hazard Analysis (PHA) in relation to incompatibilities?

• A. To design experiments
• B. To identify and evaluate potential incompatibilities and their consequences
• C. To categorize materials by color
• D. To train operators on safety drills

Answer: (B)

PHA systematically identifies incompatibilities and evaluates their consequences to manage risk. It looks at how different materials, reagents, solvents, catalysts, and even equipment interactions could come together in a process in ways that might trigger unsafe reactions, fires, explosions, corrosion, or toxic releases. Using structured analysis methods, engineers examine process flow, storage, handling, and controls to uncover where incompatible combinations could occur—whether through misoperation, equipment change, or leaks—and assess how severe the outcome could be and how likely it is. This drives the implementation of safeguards such as proper segregation, compatible materials of construction, interlocks, alarms, inerting, containment, and emergency response plans. So the main purpose is to identify potential incompatibilities and evaluate their consequences to reduce risk.
