Détermination des Zones de Planification des mesures d’urgence (ZPU) autour de sites présentant des risques d’accidents technologiques majeurs

Abstract

This article presents a methodology to establish the emergency planning zones around a site that presents risks of major technological accidents involving hazardous substances. A process to reduce the impact zones from these accidents is also presented. A concrete example involving an ammonia refrigeration system is included to illustrate the subject. The identification of the emergency planning zones is critical for public safety and is used for the preparation of emergency response plans by the site and the public emergency response organizations.
