MILANI DANTE (titolare) - 6 ECTS
Prerequisites
Understanding of basic principles of electromagnetic theory, geometrical and wave optics.
Learning outcomes
The course is designed to teach 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 contents
Basic knowledge:
Laser fundamental physics and applications
Italian laws, european directives and international standards about laser safety
Biological effects of laser radiation
Exposure Limit Values (ELVs) and Maximum Permissible Exposures (MPEs)
Accessible Emission Levels (AELs) and classification of laser products
Laser risk assessment
Laser radiation collateral hazards
Selecting control measures
Laser guards and viewing windows
Personal protective equipment
Lasers in the healthcare environment
Lasers in the industrial environment

Expertise:
Mathematical approach
How to measure the laser radiation
Manufacturer's requirements
Protective eyewear, laser guard and viewing window choice

Numerical exercises and measures
Will be proposed numerical examples and measurements:
Calculation of the Exposure Limit Values (ELVs)
Calculation of Accessible Emission Levels (AELs)
Classification of continuous and pulsed lasers
Nominal Ocular Hazard Distance
Protective eyewear, laser guard and viewing window choice
Teaching methods
Lectures (hours/year in lecture theatre): 42
Practical class and measures (hours/year in lecture theatre): 6
Reccomended or required readings
Laser safety laws, standards (IEC-EN-CEI, UNI) in force. Lecture notes
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.
