Hazard distance (IEC 62471-5:2015)
The distance at which the level of exposure has reached the level of the applicable Exposure Limit Value is known
as the hazard distance (HD) or safety distance.
Do not look into the projected light from inside the hazard distance (within RG3 range). The eyes may be damaged
by the direct irradiation. It is considered to be safe to look into the projected light from outside the hazard distance
(within RG2 range).
