Medidas de controle ocupacionais em um reator de produção de dicloroetano

Abstract

With the advent of the Ministry of Labor in 1930 and the intensification of the industrialization process in Brazil in the 1950s, there was growing concern about the increasing number of workplace accidents that were spreading across industries. Thus, faced with this chaotic situation, Ministry of Labor and Employment (MTE) issued Ordinance No. 3,214 on August 8, 1978, which approved the Regulatory Norms (NR's) related to the Consolidation of Labor Laws (CLT) and related to occupational health and safety. These laws aim to prevent accidents, ensuring the physical and mental integrity of workers in order to maintain an increasingly safe and comfortable work environment. The industrial production of chlorine soda is a highly influential activity in terms of job creation and income generation for the state of Alagoas, which has a strong flow of chemical engineers and interns operating in its acquisition. This activity has risks that demonstrate the importance of establishing occupational control measures in the workplace, such as handling reactors susceptible to reaction control with continuous mass and heat transfers, generating organochlorine fluids and industrial waste. Thus, the present study aimed to conduct a field study, focusing on the equipament for obtaining Dichloroethane (DCE), assessing the potential risks of the two reactors of the industrial plant involved in the process. Despite being a renowned company in the state of Alagoas, with an effective safety team, the lack of specific documents for these reactors and the large number of chemical engineers operating them prompted this proposal. Therefore, the development of a Risk Generation Program - PGR, identification of suitable individual and collective protective equipment for the function, and a guide for special care in their maintenance will be conducted in this study.
