Retirement of legacy scenarios
Sites classified as ICPE and SEVESO require rigorous protocols for emergency management. Extinguishing reference emergency scenarios is essential for crisis preparedness and management. This article explores the resources needed to extinguish them and the need for qualified expertise.
Understanding reference scenarios for ICPE and SEVESO sites
Reference scenarios are detailed descriptions of potential emergency situations. They make it possible to assess and compare the impacts of a project with and without its implementation, in accordance with Article R. 122-5 of the French Environmental Code. We invite you to read our article on reference emergency scenarios to learn more. SEVESO sites are legally required to create an Internal Organization Plan (POI). The POI defines the resources, procedures, and means for managing an on-site emergency situation. In the event of risks of off-site effects, the POI must be seamlessly integrated with the Special Intervention Plan (PPI). The PPI, orchestrated by public authorities, aims to protect the surrounding population.
The relationship between the POI and the PPI
The POI and the PPI must operate in a coordinated manner. The POI focuses on the initial actions to be taken as soon as an incident begins, such as securing on-site personnel and limiting environmental impacts. The PPI, in turn, takes over to manage the external effects of the incident and ensure public safety.
Key points for POI/PPI coordination:

The 2019 DREAL report highlights the importance of proper coordination between the POI and the PPI. Indeed, it emphasizes the need for proactive risk prevention, particularly for risks with environmental impacts, to ensure an adequate response and limit the consequences of incidents.
According to the 2019 DREAL report, poor coordination between the POI and the PPI is a recurring root cause of aggravated incidents on SEVESO sites. Emergency plans should be tested jointly, not validated in isolation.
Resources and tools for effective management
To extinguish reference emergency scenarios, SEVESO sites must use a range of technical and organizational resources.
