Safety and Warnings
vi Trimble M3 Total Station User Guide
C
WARNING – Only qualified and trained persons should be assigned to install, adjust and
operate the laser equipment.
C
WARNING – Areas in which these lasers are used should be posted with an appropriate
laser warning sign.
C
WARNING – Precautions should be taken to ensure that persons do not look directly, with
or without an optical instrument, into the beam.
C
WARNING – 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 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.
C
WARNING – Laser beam path should be located well above or below eye level wherever
practicable.
C
WARNING – When the laser product is not used, it should be stored in a location where
unauthorized personnel cannot gain access.
C
WARNING – Do NOT turn the class 3R laser beam to mirror like specular surfaces; for
instance, prisms, metal surfaces or windows, even unintentionally. Special precautions
should be taken to ensure eliminating such situations.
*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 health risk.
