Class 2 lasers are considered safe for normal operation.

Class 2 lasers' output power is below 1 milliwatt. All Class 2 lasers emit visible light only. In Australia, the U.K., and many other countries, only Class 2 lasers can be sold as "pointers" or for pointing purposes. (In the U.S., pointers can also be Class 3R.)
