The course is aimed at studying various aspects of safety and security in industrial applications including: chemical plants, oil & gas, dangerous goods handling etc. Starting form reliability analysis, through Bayesian statistics, reliability modelling and simulation, failure analysis the course will guide the identification of possible risk factors and will presents the most promising methodological approaches. Two practical assignment will be given focusing on industrial incidents involving chemical spills and complex plants failures.
The course addresses structurally the problem of the safety of industrial settlements and industrial plants in general, the introduction provides a basic framework and the connection with the notions learned in the Degree course with the possible completion of the existing "gap" . Part I addresses the structural patterns of cuts and collapses of industrial constructions, structures and carpentry as events often at the root of accidents. Through the analysis of theories and models, the student learns the "safe" design principles in the various scenarios considered. Part II addresses the consequences that industrial accidents can have on the environment and on people by emphasizing causal links and the interconnection between the structural, operational and human aspects of the incident phenomenon. The course is purely applicative with reference to industrial sectors considered to be "high risk" (chemical, nuclear, oil & gas, etc.).
Theoretical lectures with support of slides and in-classroom exercises, assigments and seminars.

The exam provides for a single evaluation of each of the following elements, the vote being the sum of the individual evaluations:
1. The student's delivery of the 4 calculation reports related to the Assignments,
2. Oral discussion of an in-depth report on one of the lessons discussed
3. A multiple-choice test on all subjects covered by the course.
4. Evaluation of the frequency of teaching activities (lessons and exercises) proposed in the classroom
Evaluation of the level of understanding of the theoretical concepts, evaluation of the practical design and calculation skills, evaluation of the comunication competences in a session of a real life project presentation.
Exercises, software use and seminars are offered during the lectures period.
