5.2 About the risk using UVC
:
When using normal work clothes with full cover of skin and safety glasses, the risk of permanent damage
from short-term exposure to UVC light is limited to the effect on the skin and the minimal risk of damage to
the eyes.
In connection with the use of UVC systems, warning signs should be placed warning about the use of UVC.
Systems may only be switched on when the room is secured. I.e. it has been inspected and found empty.
People at and around UVC systems will therefore not be able to be surprised by exposure without knowing
this. (Hidden injuries).
When opening the door to the room, UVC light should be switched off.
Direct view to the UV equipment should be measured with UVC radiometer and assessed in the specific
cases.
