The perception of risk in society has undergone clear changes in recent years, giving the notion of security and safety a prominent place. The demand for ＂zero risk＂ is illustrated in particular by the precautionary principle1, which requires any public or private decision-maker to take or refuse to take action, depending on the potential risk. Indeed, this evolution of society towards the social unacceptability of risk has been accompanied by a significant increase in legal actions and condemnations of establishments, professionals and the State2, which in turn has had an impact on regulations and led to the emergence of a new approach to risk management. This approach is nowadays becoming more and more important.
