Lasers can be found in various types of equipment, from solid-state laser systems to CD-ROM drives. All our laser equipment falls into two categories: uncontrolled (not requiring specific control measures) and controlled (requiring specific control measures). You will need to follow our guidelines and procedures when using these lasers in order to keep yourself and those around you safe.
Uncontrolled laser equipment includes: Class 1, Class 1M, Class 2, Class 2M or Class 3R lasers. These are considered safe provided that they are used in accordance with the manufacturer's guidelines.
Controlled laser equipment includes Class 3B and Class 4 lasers. These are subject to stringent safety controls (see below).
If you are planning on working with controlled laser equipment, you are encouraged to use engineering controls (such as enclosures) to render the equipment to Class 1.
If you will be working with controlled lasers, you will need to register with the Radiation Protection Service (at http://rsid.leeds.ac.uk/lasers/) and receive appropriate laser safety training (http://wsh.leeds.ac.uk/info/218/training).
It is not permitted to bring controlled laser equipment into the University without prior written permission of a local Laser Safety Officer or the Radiation Protection Service.
