Course handbook


This course will introduce students to advanced topics in the application of safety and risk management in chemical engineering processes. The course will not only serve as an introduction to the fundamental principles of safety and risk management, but also extend this knowledge to the practical application of the technology in industry using real-world experiential learning via a site visit and safety report.

Replacing course(s)

This course replaces the following course(s): CHEE2421. Students who have successfully completed CHEE2421 are not eligible to enrol in CHEE3425.

Learning outcomes

On successful completion of the course students will be able to:

1. Apply the fundamental principles underlying safety and risk management.

2. Implement safety and risk management in a practical context.

3. Establish expertise relevant to the practice of safety and risk management.

4. Demonstrate management skills related to planning, developing and report writing activities.

5. Interpret and apply the professional obligations related to the discipline of safety and risk management.


Topics to be covered in this course include:

  • Introduction: safety and loss prevention, definition of hazard, risk and risk assessment, scope and outline of risk management, frequency and severity, intrinsic and extrinsic safety, risk balance, Pareto principle, epidemiological approach, hazard warning.
  • Identification of hazards and basic definitions: toxicity, flammability, sources of ignition, fires, explosions, ionising radiation, noise pollution, temperature and pressure deviations.
  • Fire protection: classification of fires, fundamentals of fire suppression, fire protection systems and facilities, thermal radiation. 
  • Explosions and detonations: theoretical aspects of explosions, pressure relieving devices, dust explosions, BLEVEs.
  • Toxicity and safe handling of materials.
  • Hazard and operability studies (HAZOP): basic principles, explanation of guide words, procedures, critical examination of flowsheets.
  • Risk analysis; acceptable risks and safety priorities, cost of saving a life, frequency of accidents, safety check lists, fault trees, redundancy and voting systems, assessment of risks from complex plants.
  • Strengths and limitations of quantitative risk assessment, modelling, a systematic approach to risk reduction, human factors, management of process safety, insurance.
  • Industrial hygiene, identification MSDS, evaluating exposure to volatile toxicants.
  • Source models, flow of liquid through a hole, liquids through pipes - 2K method, vapour and gases through pipes, flashing liquids.
  • Toxic release and dispersion models, parameters affecting dispersion.
  • Fires and explosions, definitions, flammability characteristics of liquids and vapours.
