Safety Report according to SEVESO regulation in Catalonia

Abstract

Although the SEVESO regulation is established in Europe, there are still accidents with catastrophic consequences for people. Therefore, it is necessary to emphasize compliance with this regulation. The SEVESO regulation is European in scope, although its application depends on the different European countries. In the case of Spain, every region can develop its own SEVESO regulation respecting Spanish regulations RD 1196/2003 and RD 840/2015. This project will be focused only on Catalonia. Chemical plants that present hazardous chemical substances are required to submit a series of documents, including the Safety Report. In Catalonia, the Safety Report has to be prepared following the Instruction 11/2010. The main idea of this project consists of presenting a Safety Report, following all the steps dictated by the Instruction 11/2010. Data are used, at regional level, of the chemical plants present in the province of Barcelona. One of the documents presented in the Safety Report is the Risk Assessment. In there, the most representative accidents, associated with the dangerous substances present in the plant are studied. As a result of the study, areas of dangerous are calculated, depending on the scenario design. The most representative initiating events studied are the partial breakage of the equipment or the unloading/loading arm or hose, the catastrophic breakage of a mobile recipient and the confined explosion of a tank. From these initiating events and through the event tree technique, the possible final accidents have been deduced. These have been modelled to assess their possible consequences and vulnerability for people and the environment. Finally, the corresponding risk analyses have been carried out. These accidents are studied considering a statistical study of the chemical plants placed in the province of Barcelona.
