The extent of the damage depends on the quantity of absorbed radiation and on the power and inten-
sity of the radiation source.
2.2: CLASSIFICATION AND DANGEROUSNESS
Laser classifications are based on the laser’s ability to cause damage to people. All lasers are clas-
sified according to their output, from Class 1, which describes lasers which are of such low power that
they represent no hazard at all, to Class 4 lasers which are always hazardous.
The LZR lasers belong to the class IV and can produce risks, not only from direct or reflected radiation,
but also from diffused radiation. For these reasons users must take all precautions to assure that
safety guidelines are established and followed. In addition, the operator must be informed of the risks
deriving from the exposure to laser radiation, and he/she must be provided with the proper personal
protective equipment, potentially consisting of certified protection glasses for the laser radiation.
2.3: RADIATION VISION CONDITIONS
The laser beam is highly collimated and intense as it is generated and leaves the internal resonator.
If this collimated beam were to pass through to a person’s retina, this focused beam of high-dense
power can be very dangerous. Conversely, if the beam becomes divergent and spreads out, then the
beam is much less dense and therefore less dangerous. Below are some different scenarios related
to viewing the laser beam.
DIRECT VIEW OF A LASER BEAM
This type of exposure is the most dangerous and can occur through the opening to the weld
chamber, or if the optics have been removed.
DIRECT VIEW OF A REFLECTED LASER BEAM
This can happen anytime the laser beam reflects off a reflective surface. A reflected beam
can be equally dangerous as a direct view of a laser beam.
DIRECT VIEW OF A LASER BEAM EXITING A FIBER OPTIC
This can happen anytime the optical fiber is connected to the resonator. The beam can be
dangerous even if viewed from considerably far away.
