A systematic assessment used to identify, evaluate and control process hazards throughout the lifecycle of a facility.
Process Hazard Analysis (PHA) is a structured and systematic assessment used to identify process hazards, evaluate potential consequences and determine appropriate risk reduction measures throughout the lifecycle of a facility. PHA methodologies include HAZOP, What-If Analysis, Failure Modes and Effects Analysis (FMEA), Checklist Analysis and other recognized hazard evaluation techniques.
Process Hazard Analysis systematically identifies and evaluates process hazards to support effective risk management and process safety.
Process Hazard Analyses are performed during design, modification and periodic revalidation of facilities to identify hazards and verify that appropriate safeguards remain effective throughout the asset lifecycle.
Process Hazard Analysis identifies and evaluates process hazards using structured methodologies, whereas Process Hazard Reviews verify that identified hazards and safeguards have been appropriately addressed.
