DANGER: LASER RADIATION!
UNIT UNDER CLASS 3B
AVOID DIRECT EYE EXPOSURE. LASER RADAITION CAN CAUSE EYE
DAMAGE AND/OR SKIN DAMAGE
AVOID EXPOSTION TO LASER RADIATION
ALL PROTECTIVE MEASURES MUST BE APPLIED FOR MAKING THE USE OF
LASERS SAFE
This product is a so-called show laser emitting radiation with a wavelength spectrum and
producing lasers for shows.
A laser (Light Amplification by Stimulated Emission of Radiation) is a device that emits light
trough a process of optical amplification and produce electromagnetic radiation of different
wavelengths due to the controlled stimulated emissions process.
In addition to the secondary effects due to the operating laser conditions, fire risks or
burning hazards, the most important danger comes from the light source. The damages on
eyes depend on the laser wavelengths specifications, the eye distance and the elements
linked to the eye specifications. This danger is amplifies if the laser beams are focused to
tiny spots; that is why the effects on eyes are even more important while using lasers.
3B class can be dangerous under specific conditions
4 class should be ruled under strict safety warnings.
INSTALLATION OF THE UNIT
The units from 3B class and 4 class, exclusively used in open air, should be installed by
experienced and qualified professionals, trained to the specific risks of lasers and should
handle a user manual.
The area reserved for the public should be limited up to 3 meters above the ground and to
2.5 meters from the public. This zone should be indicated and marked on the ground. In this
area, it is not possible to make “pencil beams” (through the output being a narrow beam
which is diffraction-limited) in the direction of people, whatever the laser class is, except if a
determined area has been defined of 4 meters radius from the public and visibly marked on
the ground.
Only laser beams of wavelengths divergence concentrated their power at a large distance
are authorized.
OPERATION OF THE UNIT
The use of lasers is out of the reach of people when considering:
