Laser class IV: Maximum output and danger to life
Lasers of class 4 belong to the maximum output devices and/or machines. Its radiation is so intensive that any contact with parts of the human body, especially skin and eyes, causes serious injuries.
A class 4 laser may not be operated without suitable safety precautions, but by exception it is also approved for private use. The danger of a class 4 laser not only comes from the direct contact with the beam.
Diffusely dispersed laser light of a laser of this class is also hazardous to people. Appropriate fire and explosion protection measures must be taken when installing a laser of class 4. Maximum output lasers are primarily used in the industrial area, for example, for glass processing.
