Which of these is NOT a focus of process hazard analysis?

The focus of process hazard analysis (PHA) is primarily on identifying potential hazards related to processes and evaluating the effectiveness of controls in place to manage those hazards. This includes both the identification of potential hazards and the assessment of risk control measures to determine how well risks are mitigated.

The primary aim of PHA is to ensure a safe operating environment by systematically examining processes to uncover hazards that could lead to accidents or incidents, as well as reviewing existing controls to ensure they are adequate. While compliance with safety regulations is important, it is a broader aspect of safety management that is usually handled through separate compliance audits rather than the specific hazard-focused analysis of PHA.

Evaluating employee performance, on the other hand, does not directly relate to the core functions of PHA. While training and awareness of hazards are essential to safety, the analysis itself does not assess how well employees perform their jobs, as this falls within broader organizational safety performance metrics rather than the targeted focus of process hazard analysis. Thus, it is correct to identify evaluation of employee performance as not being a focus of PHA.
