Laser Safety Officer
A Laser Safety Officer (LSO) is not required to be appointed if a Class 3R product is to be used exclusively in a
venue. However, the installer, operator, owner etc should be aware of the guidelines.
Separation Distances
The classification of Class 3R lasers is carried out at a distance of 100mm from the laser aperture. The lasers should
be kept at least 100mm away from any point the audience may directly stare into the beam. As a guideline, the lasers
can be placed 0.25m above the highest surface that public can stand on, or 0.25m to the side of spaces that can be
accessed by public.
