Professional Certificate Course | Duration: 8 Hours | 8 Modules | 8 Sessions

 Course Introduction

Quantitative Risk Assessment (QRA) is a systematic and scientific approach to identifying, analysing and quantifying potential risks associated with hazardous industrial activities, processes, equipment and operations. It involves evaluating the likelihood and consequences of potential accidents, including fire, explosion, toxic gas release, equipment failure and other major industrial incidents.

This course provides comprehensive knowledge of QRA principles, risk modelling techniques, consequence analysis, frequency assessment, individual and societal risk evaluation, applicable legal requirements and internationally recognised industry practices. Participants will develop practical skills to understand, interpret and apply QRA methodologies for effective risk management, operational safety and regulatory compliance.

Course Objectives

The key objectives of this course are to:

1. Understand the fundamental principles, concepts and applications of Quantitative Risk Assessment (QRA).
2. Identify major accident hazards and evaluate potential risk scenarios.
3. Apply quantitative techniques for frequency and consequence analysis.
4. Understand fire, explosion and toxic release modelling methodologies.
5. Evaluate individual risk, societal risk and risk acceptability criteria.
6. Understand applicable national laws, regulations and international standards.
7. Develop risk-based safety recommendations and mitigation strategies.
8. Strengthen industrial safety, emergency preparedness and regulatory compliance.

Course Learning Outcomes

Upon successful completion, participants will be able to:

• Explain QRA concepts, terminology and methodologies.
• Identify major accident hazards and develop credible accident scenarios.
• Perform basic quantitative frequency and consequence calculations.
• Interpret fire, explosion and toxic dispersion assessment results.
• Understand F-N curves, individual risk and societal risk.
• Evaluate risk against established acceptance criteria.
• Identify relevant legal and regulatory compliance requirements.
• Interpret QRA reports and recommend appropriate risk reduction measures.

Training Methodology

• Instructor-led interactive presentations.
• Technical discussions and industrial case studies.
• Practical risk assessment exercises.
• Accident scenario development and analysis.
• Quantitative calculation demonstrations.
• Group exercises and problem-solving activities.
• Knowledge assessment and final evaluation.
