To develop the ability to apply models and techniques of risk control and safety management. This course is oriented towards risk assessment within Industrial contexts and/or all kinds of working activities. It should assist in the design of prevention within a socio-economic perspective. It covers both the areas of occupational safety (associated with the worker) and operational safety (associated with each activity sector).


None are compulsory. However, it is highly recommended that students have finished the curricular unit of OSH (Occupational Safety and Health), since there is continuity of contents.


Subject matter

1. Industrial Safety vs Occupational Safety, or “operational” vs “occupational” risks. ISO 31000 and ISO/FDIS 31010, standard definitions.

2. Safety Audits. Safety performance indicators.

3. Prevention of Major Accidents. The framework of SEVESO Directives and ATEX Directives. Transportation of hazardous substances. 

4. Reliability and Failure. Probabilities. Elements of Boolean Algebra. Reliability Diagrams versus Fault Tree techniques. Elements of Human Reliability Assessment (HRA).

5. Risk Assessment.

5A)- Qualitative approaches (Deviation analysis, Energy analysis, JSA, FMEA / FMECA, HAZOP, SFA); Evaluation of Risk Level. Risk Matrix. Hierarchy of risk control measures.

5B)- Quantitative /probabilistic methods (FTA, Event Trees, Bow-Tie).

6. General measures (barriers) for risk control. Prevention and protection barriers. The ALARP principle in risk management. Cost-benefit.

7. Accident investigation and analysis. Accident feedback in the cycle of organizational learning. Methods for accident investigation.

Teaching method

Teaching Methods

Lectures of 3h, combining theory and practice. After explanation of main concepts and theories, students are expected to apply them in practice using a case-study approach, preferably based on real cases. Group discussions will be held for appraisal of safety measures and strategies.    

Evaluation method

Evaluation  is based on the following 4 elements:

2 TESTS (50% weight on final classification)

2 ASSIGNEMENTS (50% weight on final classification), as follows:

- 1 assignement on relevant Legislation (European and National): specific topic per group; discussion is individual. Oral presentation and discussion

- 1 group work (2-3 students / group); the work consists of a risk assessment applied to a real working context. Output delivered in the format of a "conference paper" (template supplied by the lecturer).
