What is a Laser Safety Officer?
A Laser Safety Officer, in German Laserschutzbeauftragter (LSB), supervises the operation of lasers in classes 3R, 3B and 4 and advises the employer on protection against laser radiation. These classes can damage the eye and, in class 4, the skin and surrounding materials, including a fire risk. The role exists because laser hazards are largely invisible and require specialist judgement that operating staff usually do not have.
The legal basis is the Verordnung zum Schutz der Beschäftigten vor Gefährdungen durch künstliche optische Strahlung (OStrV). Under Art. 5 OStrV the employer must appoint a laser safety officer in writing before class 3R, 3B or 4 lasers are operated, where this is required to support the protective measures. The technical detail is set out in the Technischen Regeln zur Arbeitsschutzverordnung zu künstlicher optischer Strahlung, specifically the TROS Laserstrahlung, which covers measurement, the assessment of hazards, the maximum permissible exposure and the protective measures. The accident-prevention dimension is reflected in DGUV Vorschrift 11 (laser radiation), which complements the state-law requirements.
The laser safety officer supports the risk assessment under Art. 3 OStrV, checks that protective measures such as enclosures, interlocks, beam stops and warning signals function, verifies that the correct laser protective eyewear to the relevant scale number is available and worn, and ensures laser areas are marked and access controlled. The officer does not replace the employer's responsibility but works alongside the responsible operator and the occupational safety specialist. Findings and instructions are documented so the protective concept remains traceable.
Duties of the Laser Safety Officer
- Support the risk assessment for laser radiation under Art. 3 OStrV and the TROS Laserstrahlung
- Supervise the operation of class 3R, 3B and 4 lasers and monitor compliance with protective measures
- Verify that the correct laser protective eyewear to the required scale number is available and used
- Check enclosures, interlocks, beam stops, key switches and warning signals for function
- Ensure laser areas are demarcated, marked with warning signs and access controlled per OStrV and DGUV Vorschrift 11
- Advise the employer on the selection and substitution of laser equipment and procedures
- Instruct operating staff on safe working and on the residual hazards of the laser class
- Report defects and non-conformities to the responsible person and propose corrective measures
- Document checks, instructions and protective measures so the protection concept stays traceable
Appointment of the Laser Safety Officer
The employer must appoint the laser safety officer in writing under Art. 5 OStrV before operating lasers in classes 3R, 3B or 4, where appointment is needed to support the protective measures. The appointment names the person and defines the lasers and areas covered. It does not transfer the employer's overall responsibility for occupational safety; the officer advises and supervises, while the responsible operator remains accountable.
The officer must have the required expertise. OStrV and the TROS Laserstrahlung expect successful completion of a laser safety officer course covering the physical basics, the laser classes, the maximum permissible exposure, protective measures and the legal framework. The knowledge must be kept current; refresher training is expected at appropriate intervals, commonly recommended around every five years.
The appointment is required per operating site and laser inventory, not per device alone. Where lasers are operated at several locations or in research with frequently changing setups, the employer should ensure enough appointed officers are available and that their remit is clearly assigned. The written appointment and the proof of qualification should be retained for the supervisory authority and the trade association.
- Lasers of class 3R, 3B or 4 are operated in the undertaking
- The risk assessment under Art. 3 OStrV identifies the need for a laser safety officer
- Open-beam laser applications, processing or research setups are in use
- Medical, cosmetic or show-laser operations with class 3B or 4 devices
- Laser equipment is newly procured or a new laser process is introduced
Industries and Sectors
- Laser material processing (cutting, welding, marking)
- Medical and aesthetic laser applications
- Research, universities and laboratories
- Metrology, alignment and surveying
- Show, entertainment and stage lighting
- Telecommunications and fibre-optics
- Defence and aerospace
- Additive manufacturing and electronics
How CIVAC supports the Laser Safety Officer role
CIVAC gives the laser safety officer a register of every class 3R, 3B and 4 laser with its location, class and the protective measures assigned to it. The risk assessment input under OStrV and the TROS Laserstrahlung is documented and version-controlled, and recurring checks of interlocks, beam stops, warning signals and protective eyewear are scheduled as tasks with due dates and reminders. The written appointment under Art. 5 OStrV and the proof of laser safety officer training, including the refresher cycle, are stored centrally and flagged before they lapse. Instructions to operating staff and reported defects are logged against the laser, so the protective concept stays traceable for the supervisory authority and the trade association.
