Perspectiva de acidente químico ampliado: o caso de Madre de Deus - BA

Abstract

This study aims to quantify, analyze and evaluate the risks and consequences of the possible occurrence an expanded chemical accident caused by transportation systems through ducts at high temperatures and / or internal pressures and storage in pressurized and not pressurized oil and derivatives tanks, constituting a serious risk to people and the environment in the vicinity of the oil industry facilities, existing on Madre de Deus city / BA. Based on the population distribution, meteorological and physical characteristics of the region, defined frequencies for the occurrences of thirty one simulated events, and established the characterization of other physical effects arising from thermal radiation and pulse pressure in shock waves and through the use of different vulnerability, it was possible to estimate the probability for the occurrence of deaths for each accidental scenario simulated. The development of simulations of thirty one events was done with the assistance a computer system. The main goal of the study was to identify the impacts from major accidents, affecting groups of people from the surrounding communities of the industrial facilities of transport and storage of petroleum fuels; for this reason, the social risk is the priority index in this evaluation study and has the risk tolerance curve F-N as it’s main indicator. Based on the results obtained for the risk of occupation of the equipment of the oil industry in the city, through social risk (intolerable) and individual risk (intolerable to the pipeline and ALARP for tanks), and as compared to the standards of CETESB, it is concluded that the site of the oil industry in the Madre de Deus city, incur a high level of risk to foreign population residents in the vicinity of transport facilities (pipeline) and storage (tanks and spheres) to the probability of occurrence of an accident chemical amplified.
