Figure 1-2 Ultraviolet Light Wavelength Bands
It is very important that all precautions are taken to
prevent all UV light, whether direct or indirect, from
escaping the curing area. Exposure to UV light can
be harmful to both eyes and skin. Use the
following table to determine the permissible
exposure time to UV light on unprotected eyes or
skin.

First Aid
Store-bought creams, lotions, or aloe can be
applied to affected areas of the skin. Seek
immediate medical attention for skin burns and
direct UV exposure to the eyes.
Microwave Radiation
The lamp system utilizes high powered RF
microwave energy generated by a
magnetron to provide power to the UV
lamp. This technology is identical to that of
residential microwave ovens and like these
ovens can be dangerous if misused. The
lamp system is safe provided that the RF
screen and gasketing are intact. Any
damage such as rips or holes in the screen
may cause leakage of dangerous amounts
of microwave radiation. The power to the
lamp is interlocked to the RF detector and
will shut down if microwave leakage in
excess of 2 mW/cm
2
is detected. Any
excessive leakage will cause the system to
shutdown and the RF Detector fault will
illuminate on the front of the power supply.
