Lasers and X-ray Equipment: Registration and Inspection

210 Materials Management Building (MMB)

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 Health, Safety and Environment.

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.

To learn more about lasers, consult the Laser Safety Manual, take the appropriate laser safety training, and review some of our other resources in the right-hand column.

How can I register my laser and/or X-ray equipment?

  1. Review the information guide.
  2. Submit the appropriate application form to

Do I need training before I can operate a laser or X-ray equipment?

Yes. Personnel wishing to operate a laser must complete HSE laser safety training and receive equipment safety training from their supervisor before using the device:

  • Personnel wishing to operate Class 3B or Class 4 laser systems in research must take the online Laser Safety course.
  • Personnel wishing to operate medical Class 3B or Class 4 lasers (e.g. dental lasers) must take the online Medical Laser Safety course.
  • Personnel wishing to operate X-ray equipment used in research must first complete the Analytical X-ray equipment course, review the Information kit for X-ray workers, and receive in-person equipment safety training from their supervisor.
  • Personnel using portable hand-held X-ray fluorescence (XRF) devices must have a valid Level 1 (or higher) Natural Resources Canada (NRCan) certification.
