Process Safety, Risk Assessment, and Hazard Analysis

HAZOP Studies
Learning Objectives:
- Describe the methodology of HAZOP studies, including the systematic examination of a process to identify potential hazards and operability issues.
- Recognize key process parameters that are typically considered in a HAZOP study, such as temperature, pressure, flow rate, and composition.
HAZOP (Hazard and Operability) Studies is a systematic and structured methodology used to identify and assess potential hazards and operability issues in industrial processes, chemical plants, and other complex systems.
The primary goal of HAZOP studies is to improve safety, reliability, and operational efficiency by identifying deviations from the intended design and the potential consequences of those deviations.
During a HAZOP study, a multidisciplinary team systematically reviews the process design, equipment, and procedures to identify potential hazards, including chemical, physical, and operational hazards.
Fault and Event Tree Analysis
Learning Objectives:
- Understand how to construct a fault tree by systematically breaking down the top event into its contributing events.
Fault Tree Analysis (FTA) is a systematic, graphical method used to analyze and assess the causes of system or process failures.
