French regulations regarding risk prevention and risk management were mainly reinforced by the law, introduced on July 30, 2003, which defines both prevention measures and repair conditions for the damage caused by industrial and natural disasters. Since then, regulations have been made considerably tighter and the entire approach towards risk assessment has changed. This law has developed very interesting tools for risk assessment and risk management (some of which are unique worldwide) and has initiated the use of frequency and probability in the French system. Better information to the public, stronger regulations, new methodology for safety reports, over-hauling of land-use planning and improved accident analysis are some of the mainstays of the law. Regarding the introduction of frequencies and probabilities, as operators in France are free to choose the methodology of probability assessment, it is interesting to review the different methodologies used by operators, with their advantages and disadvantages. Some of these methodologies are based on the ARAMIS project which has defined a methodology for risk assessment. This article aims to present major different methodologies used by operators.
