Análise de risco presente em atividades envolvendo vasos de pressão contendo gás liquefeito de petróleo

Abstract

The Pressure vessels used to store liquefied petroleum gas are present in residential and industrial areas. As the activities performed directly or indirectly with these vessels must follow safety rules, as the risks of accidents occur due to the neglect of the safety aspects generated by serious and material damages. In Brazil, a main legislation dealing with safety aspects involving pressure vessels is discarded by ordinance 3,214, of June 8, 1978, by the Ministry of Labor and recently by the Special Secretariat for Labor and Welfare (SEPRT) accident investigations are verified that many safety aspects that are left unfulfilled are the main causes of accidents. For the prevention of accidents, an understanding of the risks present in the process is necessary. In this way, the present work aims to carry out a study on environmental risks and develop methodologies for analysis and control of risks through interviews with employees who carry out work activities in companies that use pressure vessels containing liquefied petroleum gas, verifying the level of knowledge on the risks and compliance with regulatory standards. The study showed that a considerable number of employees do not have knowledge or access to fundamental documents, demonstrated inability to describe the risks present in their activities and the control measures and signs that must be verified.
