Abstract. Major hazard prevention is a main challenge given than it's particularly based on information communicated to the general public. In France, preventive information is provided by the way of a regulatory document named DICRIM (In French Document d'Information Communal sur les Risques Majeurs that means in English Municipal Information Document on Major Risks). It is made by mayors and addressed to the public in order to provide information on major hazards affecting their municipalities. Unfortunately, the law imposes only few specifications concerning its content therefore one can question the impact on the general population relative to the way it is concretely realized. Ergo, the purpose of our work is to propose an analytical methodology to evaluate preventive risk communication effectiveness and apply it to the DICRIM. The methodology is based on dependability approaches. EFA (External Functional Analysis) permits the identification of (i) the service and technical functions involved, and (ii) the form, content and regulatory constraints of a DICRIM. FMEA (Failure Modes and Effects Analysis) is used to define the dysfunctions and detection elements are then listed to evaluate conformity with the 3 types of constraint. The outputs are validated by experts from the different fields investigated. Those results are obtained in order to build in future works a decision support model for the municipality (or specialized consulting firms) in charge of drawing up documents. The method is applied to a database of 30 DICRIMs. This analysis leads to a discussion on points such as usefulness of the elements missing.

Short summary
We propose a method to evaluate a French document effectiveness made by mayors and addressed to the public in order to provide information on major hazards. Our results highlight potential dysfunctions of the document, their causes and consequences and list detection elements to identify those dysfunctions. Those detections elements are about three types (content, form and regulatory compliance) and will be used to build a future evaluation effectiveness model as a decision-aid tool for mayors.
