r Hazard distance (IEC/EN 62471-5:2015)
The distance from the projection lens surface, at which the emission reaches the Accessible
Emission Limit (AEL) of risk group 2, is known as the hazard distance (HD) or safety distance. The
area where the emission exceeds the Accessible Emission Limit of risk group 2 is called the hazard
zone (HZ).
Within the hazard zone, never look into the light projected from the projector. The eyes may be
damaged by direct irradiation even if you look at the light just for a moment. If you are outside the
hazard zone, it is considered to be safe in all circumstances except deliberately staring into the light
projected from the projector.

r Risk group
The combination of the projector and the projection lens is categorized as risk group 2 when the
hazard distance is 1 m (39-3/8") or less. It is categorized as risk group 3 when the hazard distance
exceeds 1 m (39-3/8"), and it will be for professional use instead of consumer use.
In the case of risk group 3, there is a possibility of damaging the eyes by direct irradiation when
looking into the projection light from inside the hazard zone even for a moment.
In the case of risk group 2, safe use without damaging the eyes is possible in all circumstances
except deliberately staring into the light projected from the projector.
The combination of projector and projection lens classified as risk group 3 with a hazard distance
greater than 1 m (39-3/8") is as follows.
