Create a PPI alert plan

Create a Plan Individual Intervention requires asking preliminary questions at the regulatory and technical level in relation to your site, your budget, your equipment:

1. Who is responsible for setting up a PPI ?
2. What is the area to be covered for the alert?
3. How to trigger the PPI alert?
4. What types of sounds?
5. How to guarantee a 24/7 operational system?
6. How to set up a scalable, extensible and modular system?

The prefect is responsible for the PPI: it is the operational response of the authorities (specific ORSEC plan) when the disaster exceeds the limits of the site. PPI siren alerts to populations are the responsibility of the operator, under the authority of the prefect. PPI alerts must ensure the protection of employees, local residents and the environment within the PPI perimeter. When triggered, the national alert signal must be audible at any point within the PPI perimeter. The PPI alert system must be operational 24 hours a day regardless of events (power outages, damaged telephone networks, component failures, etc.), and can be monitored in real time.
