Process Hazard Analysis (PHA)

Process Hazard Analysis (PHA) is a critical risk assessment method used in industries such as chemical manufacturing, oil and gas, and pharmaceuticals—where hazardous chemicals and high-risk operations are common. The goal of PHA is to prevent accidents by identifying potential process failures in design, equipment, operations, materials, and procedures.

Using structured methods like HAZOP (Hazard and Operability Study), What-If Analysis, and Checklist Reviews, PHA systematically examines each part of the process to:

• Identify hazards and operational risks

• Evaluate the severity and likelihood of potential incidents

• Recommend effective risk reduction and mitigation strategies

Implementing PHA recommendations is essential for improving plant safety, ensuring regulatory compliance (e.g., OSHA PSM), and boosting operational reliability.
