Laser Safety Course

University of Toronto Laser Safety Committee

Radiation Protection Service

This training is mandatory for all users of class 3B or class 4 open beam lasers and meets the requirements for laser user training of the American National Standard for Safe Use of Laser ANSI Z136.1-2014

If you plan to work with class 3B or class 4 open beam lasers at the University of Toronto, use your “UTORid” to register for the course at: https://ehs.utoronto.ca/training/my-ehs-training/ . If you are a new user with previously laser safety training and laser work experience, please send an e-mail to sandu.sonoc@utoronto.ca.

If you are from outside the University or do not have an “UTORid” please send an e-mail to sandu.sonoc@utoronto.ca

Dates of training

Starting April 2018 the Laser Safety Training will be divided in two parts: Laser Safety-Theory and Laser Safety-Practical

The Laser Safety-Theory course will be offered as:

  1. Online – course number EHS736 or
  2. In-class – course number EHS737

The applicant can choose between the two versions of the theory training.

The Laser Safety–Theory must be followed by the Laser Safety–Practical (EHS738) which is offered only in-class. The completion of the Theory part is a pre-requisite for the Practical part.

The laser safety theory online (EHS736) is recommended only for users with previous experience about lasers. The users with no knowledge about fundamental principals of lasers and laser functioning are recommended to take the in class laser safety theory (EHS737).

EHS738 consists of laser hazard presentation, practical sessions demonstrating the alignment of visible and invisible lasers, emergency preparations, discussions of laser accidents, and a test.

The Laser Safety–Theory and Laser Safety-Practical together, are mandatory to be taken by a person that has not been previously trained in laser safety, and plans to work with open beam class 3B or class 4 lasers.

Important Note Regarding Registration:

  1. Participation in the ERHS738 is only accepted on completion of the EHS736 or EHS737;
  2. EHS736 (Laser Safety-Theory online) must be taken at least three business day before registered for EHS738;
  3. EHS736 (Laser Safety-Theory online), is considered completed after passing the test with a mark of 70%;
  4. EHS737 and EHS738 are offered in-class every month in two consecutive mornings.
