Refer to the specific Safety Data Sheet supplied with the coolant for further
information.
Only a water cooler with an empty tank is allowed to be shipped. Refer to
the Water Chiller manual for the procedure to empty the tank.
Laser Radiation
Laser radiation can pose a risk to eyes and skin. The danger is not only
posed by direct laser radiation, but also by scattered radiation and
reflections from the work piece or the packaging machine. The degree of
injury depends on the duration of the effect, the power and the wavelength
of the laser.
Lasers and their installations are classified into seven laser protection
classes, depending on their potential danger. Class 1 is the safest and
Class 4 is potentially the most harmful. These classes are defined in detail
in EN60825 Part 1 and are summarised below:
Class 1 The accessible laser radiation may be visible or invisible and is
harmless.
Class 1M The accessible laser radiation may be visible or invisible and is
harmless, provided additional optical instruments are not used.
Class 2 The accessible laser radiation is visible and is harmless for
accidental exposure to eyes for periods of less than 0.25
seconds.
Class 2M The accessible laser radiation is visible and is harmless for
accidental exposure to eyes for periods of less than 0.25
seconds, provided additional optical instruments are not used.
Class 3R The accessible laser radiation may be visible or invisible. It is
potentially harmful to eyes.
Class 3B The accessible laser radiation may be visible or invisible. Direct
radiation is harmful to the eyes and skin although diffuse
radiation (reflected from a matt surface) is harmless.
Class 4 The accessible laser radiation may be visible or invisible. Direct
and diffuse radiation is extremely harmful to eyes and skin and
can pose a fire risk if projected onto combustible materials.
The D-Series laser marking systems, taken by themselves, are
Class 4 and must not be used until suitable, interlocked
guarding is fitted to achieve a Class 1 laser installation that
physically prevents access to the laser radiation or automatically
disables the laser when access is required to the marking area
(for cleaning or maintenance, etc.).
