RISK GROUP

CALCULATE
Low RISK: No photobiological hazard. Trivial source for the purposes of the Directive 2006/25 EC
Moderate RISK: Compatible with the limit values associated with the Group 1 (IEC EN 62471:2009: no photobiological hazard under normal conditions of use). It could entail a risk if stared into for more than a 100 seconds accumulated in a day.
High RISK: Exposures greater than the highest acceptable for Group 1 (IEC EN 62471:2009). Risk is present, even for staring times lower than 100 seconds.
