Some events involving laser radiation use very powerful lasers with output powers of several watts. When a laser beam of such strength - even for a very short duration - hits the eye, temporary visual impairment, after-images, reading impairment and in severe cases permanent damage to the eye may be caused.
Legal requirements for events involving lasers and sound
Scope of the O-NIRSA
The Ordinance to the Federal Act on Protection against Non-ionising Radiation and Sound (O-NIRSA) came into force on 1 June 2019 and applies to all types of events involving laser radiation, independently of whether they take place in buildings or in the open air. Such events include not only laser shows but also holographic projections and astronomy presentations. In the context of this Ordinance, an event involving laser radiation is the part of an event in which the laser radiation from a laser device is visible to the audience or third parties. A laser device may consist of any number of laser projectors, of which each may possess one or more lasers.
Events involving laser radiation of all laser classes are subject to notification, except for events involving class 1 and 2 laser equipment, on condition that they do not emit radiation into the airspace. The Federal Office of Public Health must be notified of any event involving laser radiation no later than 14 days before the event via the notification portal. The document “FAQs on the notification portal for events involving laser radiation (PDF, 3 MB, 29.07.2020)” provides additional information on the notification portal, including instructions on registering and recording notifications.
Competence for laser devices of Classes 1M, 2M, 3R, 3B or 4
Anyone who carries out an event involving class 1M, 2M, 3R, 3B or 4 laser radiation must appoint a person with a certificate level 2 for events with laser radiation in the audience zone and with a certificate level 1 for events with no laser radiation in the audience zone. The competent person is responsible for the design of a laser light show as well as for the installation and operation of the laser system used at the event. The person shall fully meet the O-NIRSA requirements, which are based on the SN EN 60825-1:2014 standard. Events with no laser radiation in the audience zone may be carried out by a person with either a certificate of competence level 1 or 2. A certificate of competence level 2 is in any case required for the notification, planning, installation and operation of laser equipment of an event involving laser radiation in the audience zone. The document O-NIRSA: Events involving Laser Radiation (PDF, 169 kB, 24.01.2020) contains an overview of the O-NIRSA regulations and describes who bears the responsibility, what competence level is required, who files the notification and who is responsible for operating the laser equipment on site and staging the event.
The guidance on events involving laser radiation (PDF, 1 MB, 23.03.2023) is designed to show event organisers and competent persons how they can comply with the requirements of the Federal Act of 16 June 2017 on Protection against the Risks associated with Non-Ionising Radiation and with Sound (NIRSA) and the implementing provisions of the Ordinance of 27 February 2019 to the Federal Act on Protection against the Risks associated with Non-Ionising Radiation and with Sound (O-NIRSA).
The following examination agencies offer training and examinations for obtaining certificates of competence for levels 1 and 2:
- LASERwerk Laser- und Projektionstechnik, Fellenbergstrasse 14, 3012 Bern: Certificate of competence level 1
- Laserworld Switzerland AG, Kreuzlingerstrasse 5, 8574 Lengwil:
Certificate of competence level 1
Certificate of competence level 2
List of persons with certificate level 1 and level 2
Persons with a certificate level 1 and 2 for events with laser radiation who have given their consent to the publication of their data are listed in the ePortal NISSG.
Application for recognition of other types of training qualifications
The Federal Office of Public Health (FOPH) can verify the equivalence of other types of training qualifications.
The following applications can be submitted to the FOPH:
- Application (PDF, 311 kB, 29.07.2020) for recognition of a training qualification for the operation of laser devices of class 1M, 2M, 3R, 3B or 4 at events without laser radiation in the audience zone in accordance with O-NIRSA annex 3 numbers 3.1–3.3
- Application (PDF, 311 kB, 29.07.2020) for recognition of a training qualification for the operation of laser devices of class 1M, 2M, 3R, 3B or 4 at events with laser radiation in the audience zone in accordance with O-NIRSA annex 3 numbers 3.1–3.4
An application must be submitted at least five and a half months prior to the planned event involving class 1M, 2M, 3R, 3B or 4 laser radiation in Switzerland. There is a fee for processing applications. The guidance “Recognition of equivalence of training qualifications” (PDF, 1 MB, 29.07.2020) provides additional information.
Application for inclusion as an examination agency
The Federal Department of Home Affairs has issued an Ordinance (PDF, 362 kB, 29.07.2020) which lists the level 1 and 2 certificates of competence that a particular examination agency may issue. Anyone wishing to offer training or examination and to list level 1 and/or level 2 certificates of competence in the Ordinance may apply for inclusion with the FOPH by April 30 of each year. The guidance “Issuing certificates of competence at level 1 or 2 for events involving laser radiation” (PDF, 770 kB, 29.07.2020) provides additional information.
The Federal Office of Public Health (FOPH) is responsible for enforcing the regulations on events involving laser radiation. The FOPH runs a notification portal and examines the submitted notifications. For complex cases the FOPH may commission a measurement company for the risk assessment. The FOPH monitors compliance with the O-NIRSA and may, in order to ensure public safety, order immediate measures directly on site.
