TS11/TS15, Safety Directions
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 terminated at the end of its useful beam path and
should in all cases be terminated if the hazardous beam path (hazard distance
*)) extends beyond the limit 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 wherever
practicable.
f) When not in use the laser product should be stored in a location where unau-
thorised personnel cannot gain access.
g) Precautions should be taken to ensure that the laser beam is not unintentionally
directed at mirror-like, 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 beam irradiance or
radiant exposure equals the maximum permissible value to which personnel may be
exposed without being exposed to a health risk.
