Laser Hazard Installation Precautions
Light Hazard Warning
No direct exposure to the beam is permitted, RG3 BS EN IEC 62471-5:2015.
Light Hazard Distance and Hazard Zone
Hazard Distances for Laser Risk Group 3 variants. Operators should
control access to the beam within the hazard distance or install the
projector at sufficient height to prevent exposures of spectators' eyes
within the hazard area.
When the projector is installed overhead, allow a minimum of 3m between
the floor surface and the Light Hazard Zone.
The hazard distance is the distance
measured from the projection lens at
which the intensity or energy per unit
of surface is lower than the applicable
exposure limit on the cornea or skin.
The hazard zone is the area from the
projection lens up to the hazard
distance that encompasses where the
projected beam is considered
2
hazardous.
If the person is within the hazard zone,
the beam is considered unsafe for
exposure.
The hazard distance for this projector is related to the fitted lens:
