What is involved in the ‘plan Novi’ and is it new?

The plan Novi is an emergency plan aimed at rescuing a large number of victims in one location. It stands for no(nombreuses) vi(victimes).
It is set off by the prefect if necessary and consists of setting up a crisis group at the prefecture, putting the hospitals on alert, putting in place an operational command centre on the ground, mobilising air and land rescue vehicles and setting up a field hospital at the site.

The teams should be ready to help victims whether their cases are very urgent, such as needing flying to hospital, relatively urgent (needing an ambulance), mildly injured, or unhurt but shocked and in need of psychological support.
The plan Novi was first put in place in 2014 in connection with a mass food-poisoning incident.
