The viewpoint taken in this paper is to give a description of the interaction between regulators and regulated organisations, built on an empirical case-study in the French chemical industry. The paper stems from a collective interdisciplinary research study on risk management in high-hazard facilities. Therefore, it gathers the observations and reflections of a sociologist (Michèle Dupré), a risk engineer trained in the social sciences (Jean-Christophe Lecoze), and a trainee political scientist (Julien Etienne) who all spent some time studying the same case.
