¹ In or­der to de­term­ine the risk of a planned activ­ity with or­gan­isms in the con­tained sys­tem, the ex­tent and prob­ab­il­ity of harm­ful ef­fects to hu­man be­ings, an­im­als or the en­vir­on­ment, bio­lo­gic­al di­versity and its sus­tain­able use must be es­tim­ated. In do­ing so, the group of or­gan­isms con­cerned, the nature of the planned activ­ity and the en­vir­on­ment­al con­di­tions ac­cord­ing to the cri­ter­ia in An­nex 2.2 num­ber 1 must be taken in­to ac­count.

² In or­der to as­sess the risks de­term­ined, the planned activ­ity must be al­loc­ated to one of the fol­low­ing classes ac­cord­ing to the cri­ter­ia in An­nex 2.2 num­ber 2:

a.

Class 1: activ­it­ies with no risk or a neg­li­gible risk;

b.

Class 2: activ­it­ies with a low risk;

c.

Class 3: activ­it­ies with a mod­er­ate risk;

d.

Class 4: activ­it­ies with a high risk.

³ The risk must be de­term­ined and as­sessed again if the activ­ity is mod­i­fied or sig­ni­fic­ant new find­ings are made.

⁴ In activ­it­ies where em­ploy­ees may be ex­posed to mi­croor­gan­isms, the risk de­term­in­a­tion and as­sess­ment in ac­cord­ance with this Or­din­ance may be com­bined with the risk as­sess­ment in ac­cord­ance with Art­icles 5–7 of the Or­din­ance of 25 Au­gust 1999²⁴ on the Pro­tec­tion of Em­ploy­ees from Dan­ger­ous Or­gan­isms.
