Lasers and X-ray equipment

Setting up a new Class 3B or Class 4 laser laboratory?

All Class 3B and Class 4 laser labs must conform to the Laser Controlled Area Requirements and Emergency Shutdown Requirements approved by the Radiation Safety Committee. The schematics for the laser labs outline the key laser safety features that need to be considered as part of the laser lab set up process.

Which lasers require registration?

All Class 3B and Class 4 lasers must be registered with Environment, Health & Safety. 

The laser class is typically indicated on the device or in the

manufacturer's information that is included with the device.

Note that the following equipment may also contain or be classified as Class 3B or 4 lasers:

  • confocal microscopes
  • raman spectrometers
  • laser imaging systems
  • medical/therapeutic lasers

Class 1, 1M, 2, 2M, and 3R lasers do not require registration. Examples of class 1 lasers are grocery store scanners, while Class 2 lasers include laser pointers.
