Méthodologie d'analyse des dysfonctionnements des systèmes pour une meilleure maitrise des risques industriels dans les PME : application au secteur du traitement de surface

Abstract : According to the general principles of prevention such as they are defined by the legislative code concerning the workers’ protection, a safety risks analysis must be done in all the industrial facilities. In small and medium-sized firms, this principle of prevention is rarely respected and we may think that it is partly because the methods of risks analysis which are proposed to these firms are not well adapted. In order to measure the level of adaptability or inadaptability of the existings methods, the characteristics of these small and medium-sized firms were studied, then the decision was taken to test a method of risks analysis in real conditions so as to study the obstacles which could appear in this situation. A classical method of risks analysis (MOSAR) was used in three small and medium-sized metal finishing firms. This method was chosen among several methods from the system safety movement. During this experimental work, numerous obstacles appeared at each step of the analysis i.e. : the modelisation of the system, the identification of the various possibilities of accidents, the definition of a hierarchy and choice of protection and prevention measures. These obstacles were studied and were found to be the result of a difference of values between the small and medium-sized firms and the prevention institutions and of a lack of model for the occurrence and representation of risk in these firms, as, in the institutions. Eventually various improvements were proposed that could help increasing the application of successful risk analysis in small and medium sized firms.
