DSI - Degraded Situation Intervention

Crise Up - Degraded Situation Intervention: a concept


We live in a troubled world where every organisation must adapt to new safety challenges.

Attacks, riots, violent demonstrations, ambushes, extreme organised violence, guerillas... These are not new risks. We are all confronted by them; we must manage them and handle them differently.

Their form, nature, frequency and virulence are forcing all staff and organisations exposed to them to change their methods, perceptions and techniques in the field.

DSI, Degraded Situation Intervention, is a global theoretical and tactical approach to violent behaviour and phenomena for all professionals who want to prevent, anticipate and reduce risks.

The reality in the field is that certain events, certain threats can no longer be analysed using traditional security scenarios. If the worst happens, organisations must be able to integrate a DSI strategy; they must be clear-sighted, prepared and controlled to limit the effects.


Degraded Situation Intervention : a concept

DSI analysis applies to all violent situations where intervention is required.

Degraded situation interventions may become an integral part of your employees’ everyday. Your interventions are therefore sometimes disrupted; training in some sectors becomes necessary because of the complexity of certain situations: managing the public, intervening after an attack, a nuclear incident...
We can tailor offers to your business, to ensure the concept is a direct response to the issues you are having.
