Light Intensity Hazard Distance - Christie GS Series Service Manual

Light intensity hazard distance

This projector has been classified as Risk Group 3 per the IEC62471:2006 standard due to possible
hazardous optical and thermal radiation being emitted.
Warning! If not avoided, the following could result in death or serious injury.
• PERMANENT/TEMPORARY BLINDNESS HAZARD! No direct exposure to the beam must be
permitted. RG3 IEC 62471-5:2006.
• PERMANENT/TEMPORARY BLINDNESS HAZARD! Operators must control access to the beam within
the hazard distance or install the product at the height (greater than or equal to 3.0 m from the
floor to the beam) that prevents exposure of spectators' eyes within the hazard distance.
• EXTREME BRIGHTNESS! Do not place reflective objects in the product light path.
• Do not stare into beam when the projector is on. The bright light may result in permanent eye
damage.
• Using the projector with lenses PN: 140-109101-XX, 140-110103-XX, 140-114107-XX, and 140-
115108-XX, where the throw ratio is less than or equal to 2.0:1 results in risk group 2 emissions
from the projector. No hazard zone (Zone A) has been identified for use of the projector with these
lenses. Precautions must be taken to follow the warnings listed above to avoid serious injury.
The following diagram and table show the zones for optical and thermal radiation hazard distances:
B
• Zone A—The light intensity may cause eye damage after a momentary or brief exposure (before
a person can avert his or her eye away from the light source). The light may cause skin burns
to occur.
• Zone B—The light intensity does not pose a hazard due to the eye's aversion response to bright
light. However, staring directly into the light may still be a hazard.
