In laboratories, particularly those carrying out medical biology analyses and in premises for laboratory animals contaminated or likely to be contaminated by pathogenic biological agents, containment measures appropriate to the outcome of the risk assessment are taken.
The same applies to industrial processes using biological pathogens.
When, at the end of the risk assessment, there is still doubt as to the classification of a biological agent whose industrial use could involve a serious risk to workers’ health, the containment level and measures adopted are those corresponding to at least one group 3 agent.
A joint order by the ministers for labour, agriculture and health specifies the provisions relating to containment measures and levels depending on the nature of the biological agent and the activity in question.
