Precautionary principle

How to manage emerging risks with uncertain situations?

On each situation, we can estimate the nature and duration of the potential exposure to risk. However there are uncertainties on dangerousness at this time because of lack of stable data on the toxicity. Or, a risk refers to two criterions: the danger and the exposition. In this case, the regulation entities plan to implement the precautionary principle.


Hazards uncertainty situation and exposure reduction.

Estimating the exposure requires an analysis of:

  • the procedures and the type of operations performed,
  • the products used,
  • their propensity to go into suspension, or to deposit,
  • to identify the collective and individual protective tool in place.
