INTRODUCTION
In the extreme situation where fire-fighting resources are unable to extinguish a fire in a room containing hazardous materials, current practice is to isolate it using fire-qualified sectoring equipment. In this situation, however, the pressure effects generated by temperature variations are likely to degrade the provisions guaranteeing containment vis-à-vis the environment. This risk, which has become a regulatory requirement in the nuclear sector, can now be taken into account by adding an innovative hydraulic valve called "SPHINX".
