Management using first level lasers
Since the first stage laser is harmless and free of control, no control measures are needed. The laser does not have to use a warning mark, but it is necessary to avoid the need to look at the first laser beam unnecessarily.
Safety measures for the use of second laser
The second stage laser is a low-level laser, such as the occasional exposure to the human eye does not cause damage, continuous observation of the laser beam can damage the eyes. Therefore, the laser beam can not be looked at for a long time, which is the most important control measure for the second laser. In addition, the warning signs should be posted on the door of the second laser and the laser shell and the operation panel.
