Abstract:
The main causes of accident in chemical industry are due to deficiencies in the corporate structure, this means the effects of management and organizational variables must be incorporated into the assessment of the frequency. This work focuses attention on the frequency assessment of failure in piping, in particular loss of containment. Some methodologies for the quantification of the effects of measures of risk prevention on the frequencies of rupture of piping are available in literature. The method presented in this paper is a simple approach based on the definition of the links between the causes of failure and the measures adopted by the company to prevent them. After an overview on the causes of failure in piping, the paper describes the approach, the application to a case-study and the study of the sensitivity of the method.
