This Class 4 laser product emits
invisible infrared laser radiation in
the 10.6 µm CO
2
wavelength band.
Do not allow laser radiation to enter the eye by viewing direct or re-
flected laser energy. CO
2
laser radiation can be reflected from metallic
objects even though the surface is darkened. Direct or diffuse laser
radiation can inflict severe corneal injuries leading to permanent eye
damage or blindness. All personnel must wear eye protection suitable
for 10.6 µm CO
2
radiation when in the same area as an exposed laser
beam. Eyewear protects against scattered energy but is not intended
to protect against direct viewing of the beam—never look directly
into the laser output aperture or view scattered laser reflections from
metallic surfaces.
Enclose the beam path whenever possible. Exposure to direct or dif-
fuse CO
2
laser radiation can seriously burn human or animal tissue,
which may cause permanent damage.
This product is not intended for use in explosive, or potentially
explosive, atmospheres.
