•
A—Hazard zone. The region of space where the projection light from the laser-illuminated
projector is above emission limits for Risk Group 2. The light intensity may cause eye damage
after a momentary or brief exposure (before a person can avert his or her eyes away from the
light source). The light may cause skin burns to occur.
•
B—Hazard distance. Operators must control access to the beam within the hazard distance or
install the product preventing potential exposure of the spectators' eyes from being in the
hazard distance.
•
C—No access zone. Horizontal clearance of the no access zone must be a minimum of 1.0
meters.
•
D—Vertical distance to hazard zone. The hazard zone must be no lower than 2.5 meters (US
installations) or 2.0 meters (global installations) above any surface upon which any persons
are permitted to stand.
•
E—Represents the top view of the projector.
•
F—Represents the side view of the projector.
