EGSISTES : Évaluation Globale de la Sécurité Intrinsèque des Systèmes de Transport En Souterrain

Abstract : The objective of the EGSISTES (Global Evaluation of Intrinsic Security of Underground Transport Systems) project was the study of phenomena linked with global risk in underground transport infrastructures. The different kinds of dangerous phenomena linked with both accidental and intentional thread were identified during this project. Three families of phenomena have been enlightened: dispersion of R, B or C substances, explosion and fire. The study of those phenomena was achieved using both experimental and numerical approach. This paper is focused on fire and toxic product dispersion. The first part concerns the downstream smoke layer in confined configuration. In such a case, experiments show the quick degradation of tenability condition. Concerning toxic gases, both numerical and numerical approach show the difficulty in managing such a release to ensure safe conditions for users.
