mirror, or which could emit unwanted
reflections. Do not look through or
beside the optical sight at prisms or
reflecting objects when the laser is
switched on.
WARNING:
The use of Laser Class 3R
equipment can be dangerous.
Precautions:
To counteract hazards,
it is essential for every user to respect
the safety precautions and control
measures specified in the standard
IEC 60825-1 (2001-08) resp.EN
60825-1:1994 + A11:1996 + A2:2001,
within the hazard distance*); pay
particular attention to Section Three
"Users Guide".
Following an interpretation of the main
points in the relevant section of the
standard quoted.
Class 3R Laser Products used on
construction sites and outdoors, for
example surveying, alignment,
leveling:
a) Only qualified and trained persons
should be assigned to install, adjust
and operate the laser equipment.
b) Areas in which these lasers are
used should be posted with an
appropriate laser warning sign.
c) Precautions should be taken to
ensure that persons do not look
directly, with or without an optical
instrument, into the beam.
d) The laser beam should be termi-
nated at the end of its useful path
and should in all cases be termi-
nated if the hazardous beam path
extends beyond the limit (hazard
distance *
)
) of the area in which the
presence and activities of
personnel are monitored for
reasons of protection from laser
radiation.
e) The laser beam path should be
located well above or below eye
level whereever practicable.
f) When not in use the Laser Product
should be stored in a location
where unauthorized personnel
cannot gain access.
g) Precautions should be taken to
ensure that the laser beam is not
intentionally directed at mirrorlike,
specular surfaces for example
mirrors, metal surfaces or windows.
But, more importantly, at flat or
concave mirror-like surfaces.
*) The hazard distance is the distance
from the laser at which the beam
irradiance or radiant exposure
equals the maximum permissible
value to which personnel may be
exposed without being exposed to
a health risk.
Products with an integrated distancer
of laser class 3R this hazard distance
is 103 m / 337 ft. At this distance, the
laser beam rates as Class 1, that
means direct intrabeam viewing is not
hazardous.
