Laser Permits

All lasers in classes 3R, 3B, and 4 are required to registered with Environmental Health & Safety (EHS) under a laser permit. Laser classes 1, 1M, 2, and 2M do not need to be registered. 

To register a laser with EHS, the following information is needed:

• Make and model
• Serial number
• Laser class
• Laser type (Co2, ultraviolet, visible, etc)
• Pulsed or continuous operation
• Emission wavelength
• Energy output
• Fixed or mobile
• Building location
• Department or person laser is owned by

If a department or PI is already issued a laser permit, a new laser (Classes 3R, 3B, and 4) can be added to the permit. For a department or PI without a laser permit, an application will need to be submitted. A guide on how to submit an application for a laser permit can be found here.

If a laser permit needs to be transferred to another PI on campus, email Radiation Safety at rad@missouri.edu for assistance.
