A laser is a device that sends out a small, parallel and coherent bundle of (electromagnetic) radiation of a specific wavelength. Because of these properties, the radiation intensity in the bundle can still be high at a great distance. When living tissue is exposed to this over too long a period of time, the heat development due to the absorption of the radiation can cause damage to the tissue. A too high radiation density of the eye can inflict damage to the cornea, lens or iris. The maximum amount of acceptable radiation intensity for the skin is several orders of magnitude higher than for the eye. The required safety measures as regards the radiation risk are therefore primarily focused on the dangers for the eye.

If a staff member is or staff members are working with lasers, then the guidelines described in the 'Working with lasers' document are required to be followed. The checklist is a convenient tool to check a couple of things.
