The laser beam must be terminated and, as a rule, must be enclosed. If the laser
beam is exposed, the vertical height of the beam must not be the same as that of
the eyes.
Wear protection clothes if exposure of the skin to the laser beam
may exceed the MPE of the skin.
The laser system must be operated by only properly trained peo-
