(2) Eye protection against laser beams Take care not to allow laser beams to enter your eyes under any circumstances. For observing laser beams, ALWAYS use safety goggles that block laser beams. Usage of IR scopes, IR cameras and fluorescent plates is also recommended for monitoring laser beams safely. (3) Gallium Arsenide This product uses gallium arsenide (GaAs). This is not a problem for normal use, but GaAs vapors may be potentially hazardous to the human body. Therefore, never crush, heat to the maximum storage temperature or higher, or place the product in your mouth. In addition, the following disposal methods are recommended when disposing of this product. 1. Engaging the services of a contra.
