When operating show lasers, there is a hazard zone, the so-called show laser area, in
which the laser radiation might be higher than the highest allowed level. This area must
never be entered by unauthorized persons.
Depending on the show projected, 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 show laser area must only be entered by trained and authorized persons. Suitable
protective measures must be carried out.
If it is unavoidable to enter the show laser area, it has to be guaranteed that the show laser
area can only be entered from instructed and authorized persons. In this case suitable
preventive measures must be observed. If it is necessary for the stage scene that persons
stay in the show laser area, suitable preventive measures are to be observed to avoid
endangerments, e. g. by markings, well-practised motion sequences, etc.
The geometric borders of the show laser 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 reflective surfaces. If harmful reflections occur nevertheless,
they must be considered when defining the geometric borders.
Laser products and any installations in the laser beam must be installed in a way the
installations and the beam path will not be moved unintended.
Uncontrolled reflected radiation of laser products must be avoided, specular or reflective
objects or areas must be kept out of the laser beam, they 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 time within one room, their beam paths
must be shielded separately. If necessary, the beam path should only be accessible from
one side, the optical axle should not be aimed at windows.
The show laser area must be safely shielded from the audience area, e. g. by a higher
stage area (minimum height: 0.8 metres) or grids. The safety distance between the show
laser area and the audience area must be 1 metre to the sides. The distance from the
audience area to the top must be 3.5 metres at least.
If walls are used for shielding laser areas, walls made of brick, limestone or concrete are
