Agatec RL110 User Manual page 11

The person responsible for the product must ensure that all users understand
these directions and adhere to them.
Products classified as laser class 1, class 2 and class 3R do not require
• laser safety officer involvement,
• protective clothes and eyewear,
• special warning signs in the laser working area if used and operated
as defined in this user manual due to the low eye hazard level.
Products classified as laser class 2 or class 3R may cause dazzle, flash
blindness and afterimages, particularly under low ambient light conditions.
The rotating laser produces a visible red/green laser beam which
emerges from the rotating head.
The laser product with a stationary rotating head is clas- sified as laser
class 3R in accordance with ( *
• IEC 60825-1 (2007-03): "Safety of laser products".
(*) Class 2 product if head is rotating.
Class 3R laser products:
Direct intrabeam viewing may be hazardous (low level eye hazard), in
particular for deliberate ocular exposure. The risk of injury for laser class
3R products is limited because of:
a) unintentional exposure would rarely reflect worst case conditions of
(e.g.) beam alignment with the pupil, worst case accomodation.
b) inherent safety margin in the maximum permissible exposure to laser
radiation (MPE)
c) natural aversion behaviour for exposure to bright light for the case of
visible radiation.

WARNING
From a safety perspective class 3R laser products should be treated as
potentially hazardous.
Precautions:
Prevent direct eye exposure to the beam. Do not direct the beam at other
people.
WARNING
Potential hazards are not only related to direct beams but also to reflected
beams aimed at reflecting surfaces such as prisms, windows, mirrors,
metallic surfaces etc.
Precautions:
Do not aim at areas that are essentially reflective, such as mirror, or which
could emit unwanted reflections.
