In practice, there are two main types of exposure situation: "deliberate use" and "potential exposure".

• In activities where micro-organisms are deliberately used (as in biotechnology and research laboratories), we know the precise identity of the biological agents used, the quantities used and where they are present.

• In situations of potential exposure (work in the healthcare sector, work in contact with animals, agriculture and the agri-food industries, wastewater treatment, waste disposal, etc.), we can only identify the most likely biological agents, given the activity....
