This ANSI laser is harmful through direct exposure and from mirror light reflections. It emits visible and invisible beams. Additionally, on our campus we have lasers that fall under this classification: HeNe, Diode, and Argon lasers.

Class 3B

Explanation:

The Class 3B laser products are well thought-out to be more harmful and relatively dangerous under straight and spectacular reflective viewing conditions. A Class 3B laser product, however, is on the whole not a fire hazard, diffuse reflection hazard or a laser generated air contaminant (LGAC) production hazard but could be hazardous when under mirror light reflection.
