What are the risks?

A laser beam in the eye can cause partial or complete blindness and cause nasty (subcutaneous) burns on the skin. Laser dyes are often carcinogenic and the maintenance of lasers is associated with electrical risks.

Risks of laser light
Both the direct and reflected laser beam can be dangerous for the eyes and skin. Lenses and mirrors can further increase the power and energy density. Prevent accidents by obeying the rules.

Risks of chemicals and gasses used
Laser dyes are often carcinogenic. Also the solvents used for these are often toxic and sometimes carcinogenic. Read here about the measures you can take. See also: working with dangerous substances and gasses

Electrical risks of lasers
During maintenance activities in particular, there is an increased risk of parts being live. Use earth rods to discharge large condensers, see also: working with electricity.
