Hazard distance (IEC 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.

Risk group
The projector is categorized as the risk group 2 when the hazard distance is 1 m (39-3/8") or less. It is categorized
as the 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.
This projector is categorized as risk group 2.
