For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.


The objective of the course is to give the students an understanding of analysis principles and concepts and give training in how to apply their abilities to improve human safety, to protect the environment, and to improve process quality and productivity.

The course prepare students to approach the technical skills required to fulfil the following tasks:
* To understand when to apply qualitative and quantitative risk analysis technique
* To work as a member of team for carrying out a hazard identification and risk assessment
* To prepare a scope of work for any risk assessment project
* Being able to control a project concerning risk analysis
* Being able to evaluate and judge any work of risk analysis
* Being able to use the results of risk analysis in decision making


In this course the following techniques will be reviewed:

· Major hazard accidents
· Basic concepts of risk,
· Hazard identification procedures
· Consequence analysis and modelling (discharge models, dispersion models, fire and
explosion models, effect models,...)
· Estimation of incident frequencies (estimation of incident frequencies from historical
data, frequency modelling techniques e. g. FTA and ETA)
· Human factors in risk analysis
· Calculation and presentation of risk (individual risk, societal risk)
· Risk management
· Ecological/environmental risk assessment
· Risk of chemical reactions e. g. chemical reactivity and run away
· Design of equipment and systems (design, inherent safety, lay out, components and

Seminars(S) and Tutorial(T)
1. Human reliability and human factors in risk analysis(S)
2. Risk analysis and evaluation(S/T)
3. Environmental impact of accidents(S)
4. Risk management and emergency planning(S)
5. Storage of hazardous materials and transportation(S)
6. Emergency exercises(T)


The course consists of lectures, work-shops, a project work, seminars, training by means of some computer programs on HAZOP, FTA, and consequence analysis. A study visit to a company producing and handling hazardous chemicals will be arranged.


The literature consists of a specially written text on risk assessment(compendium), excerpts from textbooks on risk assessment, selected reports and articles gathered in a binder. The binder is sold to the students at the beginning of the course.


Written examination (40%), a project work (60%). The project work will be carried out in groups.
