Abstract

Abstract Measuring organizational safety performance is critical in managing production systems. This practice allows decisions to be made objectively and based on data analysis. In the study of resilience engineering applied to the safety of production systems, there is interest on the part of the scientific community and companies in identifying, in the different processes of organizations, indicators to measure resilient performance in safety management. This study aims to discuss and analyze qualitative and quantitative methods to identify the potential for resilience in safety management and support new research on resilience engineering applied to safety performance management in industries with high technological risks. The methodology used included a systematic review of national and international literature from the last ten years. The results obtained provide a critical analysis of the methods used to define safety indicators applied through resilience engineering to occupational safety management in organizations that deal with high technological risks. Qualitative methods for generating safety indicators from the perspective of Resilience Engineering have proven to be a better way, as they apply the concepts of Safety I and Safety II and early warning indicators.

Abstract

A blendagem de resíduos é uma técnica de mistura de diversos resíduos, viabilizando-os para aplicação em fornos de cimenteiras, substituindo a matéria-prima ou energética do processo de fabricação do cimento. Todavia, existe o receio da potencial poluição do ar oriunda da blendagem, e das consequências na saúde das populações que residem próximo a essas empresas em decorrência desta poluição. A pesquisa teve como objetivo analisar os agravos na saúde das populações vizinhas às unidades de blendagem no município de Magé, região metropolitana do Rio de Janeiro. Foram levantados dados da qualidade do ar fornecidos pelo INEA, dados de internações por doenças respiratórias, providos pelo site DATASUS e aplicação do questionário de Sintomas Respiratórios do British Medical Research Council. Os resultados mostraram a existência de correlações entre sintomas respiratórios, qualidade do ar e o processo de fabricação do blend em Magé.

Abstract

Despite the notable benefits that dams bring to society, they involve immediate and potential risks and impacts, which makes dam safety extremely important. This narrative review paper compares dam safety concepts, including that established in the Brazilian National Dam Safety Policy – PNSB, as well as analyzes the supervision difficulties reported by Brazilian federal and state agencies. Several national and international institutions define dam safety, but considering those presented in this paper, convergency was found out regarding the concept of maintaining structural integrity and operational safety in order to preserve life, health, property and environment. Dams in Brazil are inspected by several public bodies, depending on their priority use and the domain of the body of water in which they are located, each with prerogatives to regulate the matter. In view of the significant increase in the amount of accidents and incidents in 2019 and 2020, it is clear that there is a vulnerability to be corrected in the safety management of Brazilian dams due to their dependence on the treatment of deficient or non-existent technical information and on a lack of specialized staff in dam safety for inspection activities.
