EuroLite LAS-7 Mode D'emploi page 20

The optical components must be firmly fixed at the wall etc. All holding elements must also be firmly fixed.
Audience area
In the audience area, the thresholds for radiation and radiation intensity must never be exceeded.
Person must never be exposed to laser radiation higher than the highest allowed level.
The operator has to make sure that laser radiation – also reflected laser radiation – higher than the highest
allowed level is avoided by technical or organisational measures.
Showlaser area
When operating showlasers, an area of danger is created, the so-called showlaser area in which the laser
radiation may be higher than the highest allowed level. This area must never be reached by any
unauthorized person.
Depending on the intended show, the laser area must be kept as small as possible. There should only be
persons in the laser area whose stay is absolutely necessary.
The showlaser area must only be entered by trained and authorized persons. Suitable protective measures
must be carried out.
The geometric borders of the sholaser area must be calculated or measured before starting the operation.
Laser radiation must only extend as far as necessary for the show. The beam must be limited by a diffuse
surface, so that dangers due to indirect or diffuse reflections are minimized.
There must not be any highly reflexible surfaces. If harmfull reflections occur nevertheless, they must be
consired when defining the geometric borders.
Laser products and any installations in the laser beam must be installed in a way the installations and the
beampath cannot be moved unintended.
Uncontrolled reflected radiation of laser products must be avoided, specular or reflexible objects or areas
must be kept out of the laserbeam, must be removed or covered.
In order to protect from dangerous reflections, tools, accessory and adjustment devices being used in the
laser area should not have specular surfaces and people in the laser area should not wear specular objects.
If several laser products are operated at the same tiem within one room, their beampaths must be shielded
separately. If necessary, the beampath should only be accessible from one side, the optical axle should not
be aimed at windows.
The showlaser area must be safely shielded from the audience area, e.g. by a higher stage area or grids.
The safety distance between the showlaser area and the audience area must be 1 m to the sides. The
distance from the audience area to the top must be at least 3.5 m.
If walls are used for shielding laser areas, walls e.g. made of brick, limestone or concrete are considered as
suitable. Other shieldings may also be used if the comply with the requirement of DIN EN 12 254.
Control units
The control units of a showlasers must lie outside the showlaser area and the complete showlaser area must
be controllable from this point.
The laser product must only be accessible by authorized persons.
The showlaser must never be operated unattended!
During a show, the laser product must never be repaired or adjusted in a way that the laserbeam is
corrected.
Outside the laser show, the beam must be interrupted closed to the laser or be shut off.
Operating staff
The laser-light-show must only be carried out by a trained person. This person must control the laserbeam
during the show and immediately switch off the device or interrupt the laser beam in case of failure of the
device, unsecure operational conditions or unrest in the audience.
