Méthodologie de risquesSciences de l'Ingénieur 8 (MRI)

Assess and map the risk of an existing or ongoing industrial site (ICPE/SEVESO).

1- Methodology

2- Definition of analysis

• Concept of the study cube,
• Objectives of the analysis.

3- Summary of incidents

• The HAZOP method.

4- Estimation of consequences

• Liquid and gaseous leakage,
• Evaporation rate of a liquid sheet,
• Atmospheric dispersion,
• Toxicity.

5- Estimation of frequency of occurrence

• Reminder of fault tree analysis method
• Trees of events,
• Introduction to human reliability analysis.

6- Measures, calculations and presentation of the risk estimate

• Risk indices,
• Individual risk,
• The societal risk.
