Process Hazard Analysis (PHA) is a systematic approach used to identify and evaluate potential hazards associated with industrial processes. It aims to prevent accidents by analyzing the processes, equipment, and materials involved. PHA typically involves techniques such as Hazard and Operability Study (HAZOP) and What-If Analysis to assess risks and recommend safety measures. The PHA process is essential in industries like chemical manufacturing and oil and gas, where hazardous materials are handled. By identifying risks early, organizations can implement controls to minimize the likelihood of incidents, ensuring a safer working environment for employees and the surrounding community.
