The course is devoted to the knowledge of techniques for reliability evaluation in process plants and to quantitative risk assessment in stationary process plants and multimodal HazMat transportation. Concerted application of skills in environmental and accident risk mitigation.
In-class lessons. Tutorials and numerical case-studies. Self-directed team-work.

Qualitative and quantitative risk assessment. General Risk Model. Unwanted events classification. Personnel and process safety. Complementing economics with safety. Relevant national and international regulations.
2.Occupational Safety
Statistics and accident frequency evaluation. Performance indicators of personnel safety. Human factor and risk determining factors. Occupational health and ergonomics.
3.Hazard Identification and Analysis
Gas, vapour and dust hazardous properties and their evaluation. Risk indicators. Hazard identification tools and application to case-studies. Fire, explosion, instability and reactivity. Sound and vibration: basic concepts.
4.Reliability engineering and frequency evaluation
Theory of industrial reliability and elements of statistics. Frequency and probability.
Human and system reliability. Fault-tree analysis of complex systems. Case-study selection.
5.Severity and damage evaluation
Source term models. Dispersion modelling of neutral and dense gas and cold jet. Fire scenarios modelling (flash fire, pool-fire, jet fire, fireball, ventilation controlled fire). Explosion modelling (vapour cloud explosion, physical explosion, runaway, cold and hot BLEVE). Notable major accidents and relevant lessons.
6.Quantitative Risk Assessment
Local, individual and social risk. Damage models (threshold and probit approach). Risk acceptability criteria. Risk mitigation and design of emergency relief systems. Land use planning. Risk in multimodal HazMat transportation. HSE risk management. Risk perception.
Lecture slides are delivered in reduced electronic format at the end of the pertinent semester. Supporting material for tutorials is provided during the lessons.

In strict accordance with the official program of Genoa University - academic year 2016-2017: 27th September 2016.
The oral final exam is set to evaluate student’s knowledge level, design and application abilities, as well as effective technical communication skills. It includes a critical discussion on the team case-study performed and completed during the lesson period.
The aim is to provide knowledge and solving capabilities on safety and loss prevention issues in the process industry, with emphasis on reliability, environmental and personnel/process risk. The effectiveness assessment during the course development is performed by monitoring capabilities in numerical applications, lessons learned form incidents and team case-studies.
No formal requirements are foreseen; Chemical Plant and Chemical Engineering Principles represent useful background knowledge.
