c. SAFETY INTRUCTIONS FOR LASERS
According to EN/IEC 60825-1 regulations, this laser is classified under 3B class. Direct eye exposure can be dangerous
DANGER: LASER RADIATION!
UNIT UNDER 3 B CLASS
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:
-
That the unit is situated at 3 meters above the floor at least
-
That a safety area is defined within 5 meters radius
-
The user takes the responsibility that the units under 3B class or 4 class are mounted by a qualified technician and experienced
to the risks of lasers. This technician must stay around during all the time the lasers work and he must be able to stop the units
in case some technical problems would occur. While the installation is on, the technician should wear protective glasses.
Please remind the following remarks:
-
Laser light is different from any other light source with which you may be familiar. The light from this product can potentially
cause eye injury if not set up and used properly.
-
Laser light is thousands of times more concentrated than light from any other kind of light source. This concentration can cause
instant eye injuries, by burning the retina. Even if you can not feel heat from a laser beam, it can still injure or blind you or the
audience.
-
Never look at the laser aperture or laser beams.
-
Do not direct the laser beam to people.
-
Do not leave the device running without the presence of qualified professionals.
EXPELEC can not liable for damages caused by incorrect installations and unskilled operation.
