Laser Safety

Class 3B and 4 lasers are regulated in Alberta under the Radiation Protection Regulation. This regulation requires that Class 3B and 4 lasers be registered before they can be used. Safety Services administers of the University's laser safety program and must be contacted prior to the acquisition and use of any lasers that fall within the Class 3B and 4 classification. 

Laser Safety Training is required for users of Class 3B and 4 lasers. Contact Safety Services to enroll.

The registration process requires a formal compliance inspection to be carried out to ensure that the laser meets certain specified safety standards before it may be registered. The safety standard that has been adopted under the Radiation Protection Regulation for Class 3B and 4 lasers is the American National Standard for Safe Use of Lasers, ANSI Z136.1 - 2014.
