Classification of hazards:
The classification describes the potential risks that could occur depending on the
purpose of the application and the length of irradiation. The risks must be
assessed and classified depending on the use of the UV LED light source.
The measurement distance for the classification of hazards is set at 200 mm
according to IEC 62471.
The risks groups defined in IEC 62471:
Risk-free means that, based on this standard, there is no health hazard through
irradiation.
Risk Group 1 – Low risk
Does not pose an irradiation hazard under normal performance and use.
Risk Group 2 – Medium risk
No hazard based on the natural human reaction to a very intense glare or
generation of heat.
Risk Group 3 – High risk
Can be hazardous even in the case of brief exposure to irradiation.
CAUTION!
Attention:
The BlueCure lamp emits UV and brief visible light with an intense glare.
Never look at the UV light source without UV protective glasses.
