What is the purpose of the Process Hazard Analysis (PHA)?

The purpose of the Process Hazard Analysis (PHA) is to identify and evaluate major processes that could pose hazards to workers, the public, and the environment. This systematic approach allows organizations to examine potential risks associated with their processes in detail, highlighting areas where safety improvements can be implemented. By analyzing the substances, equipment, and operations involved, a PHA helps to identify weaknesses and potential failure points, enabling organizations to develop strategies to mitigate risks and enhance safety protocols. This proactive measure is an essential component of risk management and safety compliance within industries that handle hazardous materials or complex operations.

The other options, while related to workplace functions, do not align with the specific goals of a PHA. Compiling employee work hours and assessing performance are more focused on human resources and personnel management rather than process safety. Enforcing disciplinary actions pertains to management practices rather than the methodical evaluation of processes to ensure safety.
