Hazard analysis: Analyzing risks

The hazard study specifies the risks to which the facility may expose, directly or indirectly, the interests referred to in Article L. 511-1 of Code de l’environnement in the event of an accident, whether the cause is internal or external to the facility. Where necessary, this study gives rise to a risk analysis which takes into account the probability of occurrence, the kinetics and the severity of accidents, according to a methodology which it specifies. It defines and justifies measures to reduce the probability and effects of accidents.

The content of the hazard study must be commensurate with the importance of the risks generated by the facility.

The risk analysis must cover the whole plant, which can be divided into several systems or zones to facilitate the study.
