Preventive measures
Étude de dangers des ICPE

There are three stages of prevention:

• primary prevention, which involves combating risks before any problems arise. The aim is to combat risk at source;

• secondary prevention, whose synonym could be the word "screening". Secondary prevention seeks to reveal an impairment in order to prevent a risk. This level of prevention reinforces a means of prevention already in place;

• tertiary prevention, aimed at dealing with aberrations. It's about reacting to emergencies.

Preventive measures are approached from two angles: organizational and technical.
