CAUTION: Eye injuries caused by improper handling of UV or blue light beams
The UV beam of the deuterium lamp or the blue light beam of the LED can cause serious
injuries through direct eye and skin contact. This results in the following safety mea-
sures when working on the switched on device with access to the light beam exit:
▸
Always wear UV protective goggles (in accordance with standard EN 170)
▸
The UV goggles do not provide protection against injuries caused by blue light beams,
therefore switch the LED off when working.
▸
Use the lamps only when they are perfectly safe. Operation is not allowed when the
lamp, supply lines or operating parts are visibly damaged.
Cover every sensor tube with a protective cap during tunnel cleaning.
