The course is designed to teach the industrial laser applications and to provide the necessary knowledge and to understand the rational of laser safety. At the end of the course the students learned to classify a laser product, carry out laser risk assessment and prescribe prevention and protection measures in all work environments. The program, articulated in lectures and practical lessons, meets the training requirements for the TSL outlined by the CEI (Italian Electrotechnical Committee) and for LPA (Laser Protection Adviser) outlined by IEC International Standards.
Course Prerequisites
Understanding of basic principles of electromagnetic theory, geometrical and wave optics.
Teaching Methods
Lectures through which the student learns the main theoretical aspects and models Practical class aiming at the application of the studied models
Assessment Methods
Written test generally, which includes theory and numerical exercises. The sufficient students can be accept the mark gotten in the written test or they can do a oral test. The oral exam is required to the "LAUDE". The competences required and tested are - theoretical knowledge of the topics covered such as (laser safety professionals, reference standards, laser biological target interaction, prevention measures, etc.) - ability to calculate MPEs - ability to classify a laser product - ability to determine the characteristics of protective shields or PPE - ability to make a simple risk assessment
Texts
Laser safety laws, standards (IEC-EN-CEI, UNI) in force. Lecture notes
