Which of the following is NOT a common method for Process Hazard Analysis (PHA)?

• A. HAZOP
• B. FTA
• C. Process Mapping
• D. FMEA

Answer: (C)

Process Hazard Analysis (PHA) is essential for identifying and assessing potential hazards associated with industrial processes. HAZOP (Hazard and Operability Study), FTA (Fault Tree Analysis), and FMEA (Failure Modes and Effects Analysis) are all recognized methodologies used to systematically evaluate risks and identify hazards in various processes. HAZOP is a structured technique focusing on the possible deviations in process parameters and their impacts, making it suitable for complex processes. FTA is a deductive approach that uses logic diagrams to break down failures into their root causes, allowing teams to visualize how specific failures can lead to undesired events. FMEA emphasizes identifying potential failure modes within a process, assessing their impact, and prioritizing mitigation strategies based on severity and likelihood. In contrast, while process mapping can provide a visual representation of workflow and may help identify areas of concern, it is not explicitly classified as a PHA method. Instead, process mapping is more focused on outlining the sequence of operations and understanding process flows rather than analyzing hazards per se. This distinction makes it clear why process mapping is not viewed as a common method for PHA. It serves a different purpose—mainly aimed at improving efficiency or understanding process dynamics rather than assessing hazards directly.
