Possible Personal Injury - Hitachi LM-C300 Series User Manual

If exposed to intense laser radiation, even briefly, or to less intensity but longer duration, both the cornea
and the retina can be burned and irreparably and permanently damaged.
Direct exposure to focused radiation can burn the skin. In addition, it is necessary to bear in mind that
there may be collateral ultraviolet radiation along with the main radiation. Prolonged exposure may cause
skin cancer.
Enclose the beam path whenever possible. Direct or diffused laser radiation can seriously burn humans
or animals.
U.S. customers should refer to and follow the laser safety precautions in ANSI Z136.1-1993, American
National Standard for Safe Use of Lasers. Procedures listed under the Standard include the appointment
of a Laser Safety Officer, operation of the product in an area of limited access by trained personnel,
servicing of Laser Marker only by trained and authorized personnel, and posting of signs warning of the
potential hazards.
European customers should refer to and follow the laser safety precautions in EN 60825-1, Radiation
Safety of Laser Products, Equipment Classification, Requirements, and User Guide.
Materials processing can generate air contaminants such as vapours, fumes, and/or particles that may
be noxious, toxic, or even fatal. Safety Data Sheets (SDS) for materials being processed should be
thoroughly evaluated and the adequacy of provisions for fume extraction, filtering and venting should be
carefully considered. Review the following references for further information on exposure criteria:
ANSI Z136.1-1993, American National Standard for Safe Use of Lasers, Section 7.3 U.S. Government's
Code of Federal Regulations: 29 CFR 1910, Subpart Z. Threshold Limit Values (TLV™s) published by
the American Conference of Governmental Industrial Hygienists (ACGIH).
It may be necessary to consult local governmental agencies regarding restrictions on the ventilation of
processing vapors.
