Développement d'objets intermédiaires (OI) pour conduire un collectif de salariés à développer des solutions de prévention au risque chimique.

In the symposium (coordinated by Valérie Saint-Dizier and Alain Garrigou) and in the context of chemical risk prevention in the workplace, we propose a research-intervention model to conduct a prevention project. It is a question to show how the development of intermediate objects (IO) of prevention, constituted in resources, allow mutual learning between actors of different hierarchical and disciplinary levels. The objectives of this contribution are twofold: - To make visible an IO development methodology - Open on the conduct of prevention projects in reference to the work on the conduct of design projects. In this context, illustrations from research interventions allow to question and describe the role of these IOs. [ABSTRACT FROM AUTHOR]
