Danger from irradiation
The radiation source of the UVAHAND LED emits UVA radiation and visible light.
DANGER!
If improperly handled,
UV radiation can damage skin and
eyes! It can lead to severe sunburn, premature ageing of the
skin, inflammation of the retina and conjunctiva, and possibly
to skin cancer.
The instructions below must be observed
when working with the unit:
The UVAHAND LED must always be
held or installed in such a manner that
neither the user nor other persons are
exposed to direct radiation.
UV-absorbent plastics or metal plates
may be used for screening.
Depending on the surface of the ob-
jects to be irradiated, personal protec-
tive equipment must be worn if neces-
sary to protect the eyes and skin
against indirect radiation.
Protective goggles for the eyes should
be to standard BS EN 170 (max. spec-
tral transmittance (313 nm) 0.0003%,
(365 nm) 0.3 %) and should be for di-
rect and peripheral exposure (side
shielding).
Protective gloves should have a
Clothing Protection Factor (CPF)
of 30+. The CPF corresponds to
the protection factor offered by sun
creams.
UV radiation accelerates the
ageing of materials. Consequently,
any protective equipment that is
damaged or which exhibits signs
of ageing must be replaced.
Never look directly into the lamp
when it is switched on.
The UVAHAND LED must never
be operated without the safety
glass plate or with a damaged
safety glass plate.
CAUTION!
UV radiation can cause material damage to electronic components.
When processing, for example, EPROMs in the vicinity of the
UVAHAND LED, they must be protected against UV radiation.
CAUTION!
UV radiation accelerates the ageing of materials. UV-sensitive
objects and surfaces must therefore be protected from radiation.
NOTE!
Protective equipment is listed in the chapter "Ordering data for
units, replacement parts and accessories."
