Emergency plans
 

For Seveso AS sites, an Internal Operation Plan (POI) and Specific Response Plan (PPI) must be implemented to deal with a serious risk likely to result in a major accident.

These two operational tools can also be imposed by the Prefect in other classified installations for which the planning of emergency situations is deemed necessary (facilities presenting serious and very specific risks to their environment, highly urban therefore particularly vulnerable environment etc.).

Seveso AS industrial site operators must be capable of internally controlling an accident and restoring the installation to the safest possible condition. The Internal Operation Plan (POI) is implemented by the operator. Its objective is to define its organisation and adapted internal resources to control an accident within the boundaries of the site. This document prescribes the organisation, resources and intervention strategies by analysing potential accidents. The POI is subject, upon the operator’s initiative, to periodic tests (drills) at least every three years.

Operators are in charge of managing operations within the framework of the POI, with their internal resources and, when necessary, help from private external resources. If operators call for fire and emergency services, the standard procedures of the emergency organisation apply. The director of emergency operations (DOS) is then the competent policing authority (mayor or Prefect depending on the case) and the emergency operations commander (COS) is a firefighting officer (articles L.1424-4 and R.1424-43 of the general local authority code). The COS commands the public and private resources mobilised. He collects technical information regarding the installation from the operator.

The Prefect establishes the Specific Response Plan (PPI) which is one of the specific provisions of the ORSEC plan. The PPI mobilises public emergency services (firefighters, gendarmes, police, emergency medical services), all State services (DDE, DRIRE, DDASS etc.), municipalities and private players (operator, associations, network operators etc.).

In order to define the operational measures and scope of the PPI, all hazardous phenomena and their effects should be taken into account, regardless of their intensity and probability: these scenarios (leading to the abovementioned hazardous phenomena), representative of the potential hazard of an installation, determine the population protection and intervention strategies to be adopted, according to the nature and scale, seriousness and kinetics of the effects.

In the case of an accident exceeding the extremities of the facility, the Prefect assumes leadership of emergency operations by implementing the measures prescribed in the PPI. The population protection measures stipulated by the PPI will be progressively lifted by the Prefectural authority when all risks to the population are eliminated. However, emergency or other types of missions may continue with a view to progressively restoring normality. 2Regulatory references2
