2.9 Safety Information for Zinc
Selenide Lenses
CAUTION
The laser scan lens consists of coated zinc selenide and contains an extremely
small amount of the radioactive substance thorium. This applies to all CO
2
laser
marking systems available on the market.
Zinc Selenide
This material contains components which are dangerous to health!
Zinc selenide is toxic when inhaled or ingested. Dust may lead to irritation of the
eyes and the respiratory system. Do not eat, drink or smoke while handling zinc
selenide. Wash hands thoroughly afterwards.
For detailed information see safety data sheet in the chapter "Appendix".
Thorium
Thorium is a potential health hazard when inhaled or ingested. The thorium layer
is embedded within other layers within the lens. Thus no radioactive material can
escape from the coating as long as the lens is intact. Avoid any surface scratches
of the lens.
There is no danger of radiation during normal handling and cleaning of the
optical system!
In case of a broken lens...
...do not inhale material particles! In case of breaking of the laser scan lens
please collect the fragments wearing gloves (avoid raising dust when sweeping
up the pieces), pack the fragments into a closed plastic bag and send them back
to Videojet Technologies Inc. for disposal.
Maintenance of the Laser Scan Lens
Information concerning the maintenance of the laser scan lens can be found in
