96164 - SICUREZZA ED ERGONOMIA DEI SISTEMI INDUSTRIALI M

Learning outcomes

The course aims to introduce the student to the knowledge and management of problems related to the safety and hygiene of production systems in compliance with current legislation and in a systemic and multidisciplinary approach. The course presents the framework of the problem in the light of the new recent regulatory interventions (TU n.81 of 9/4/2008, Legislative Decree N.106 of 3/8/2009). The course proposes models and methods of support for diagnostics, prevention and protection from occupational risks, to ensure the safety of workers, company assets and the environment.

Snock Ciriello method. OCRA (Occupational Repetitive Action) method. Biomechanical overload from working postures. the TACOs method for Postures. Principles of anthropometry and ergonomic design of workstations according to anthropometric principles. Case studies and numerical applications. Tutorials.

Mechanical risk

Teaching methods

handouts and exercises provided by the teacher

Assessment methods

written exam with:

- a theoretical theme to be answered through a technical report on the topic indicated

- a numerical application on ergonomics.

It is also required to carry out a group project on the analysis of the risk from biomechanical overload, to be presented in the classroom at the end of the course (or in online mode through Teams)

The project and the presentation will be evaluated (from 0 to 2 pt to be added to the vote of the Safety module) and are a necessary condition to proceed with the verbalization.
