Análise de áreas classificadas em indústria alimentícia: estratégias e adequações visando a segurança dos trabalhadores em um projeto de prevenção e combate a incêndio

Abstract

This paper addresses workplace safety in a food industry, focusing on the analysis and proposal for improvements in the fire prevention and fighting project in classified areas. These areas are places where there is the presence or probability of formation of explosive atmospheres, requiring special care in accordance with Regulatory Standard (NR) 20. The research seeks to identify and classify these areas within the industry, propose adjustments in accordance with NR-20 and NPT 025 standards, and evaluate the effectiveness of the safety measures already implemented.The monograph is justified by the need to protect the health and safety of workers and mitigate risks to the industry’s surroundings, preventing catastrophic consequences. Compliance with standards is essential for the safety and efficiency of operations, reducing operational risks and promoting a safe work environment. The methodology applied included normative analysis, the selection of a case study in a food industry with classified areas, and the proposal for improvements in the fire fighting system, with an emphasis on meeting regulatory requirements. As a result, a proposal was drawn up to implement classified areas, with changes to the layout and adaptation of safety features. The main actions include the creation of two storage rooms for flammable products, one indoors and one outdoors, both with a capacity of 20,000 liters, totaling 40,000 liters. The outdoor room will use natural ventilation, dispensing with mechanical exhaust. Fire extinguishers were recommended in accordance with NPT-25, and storage will be done in stacks. In addition, the project includes a new fire prevention reserve, a fire pump, risk isolation of the sheds and new hydrant connections. These results seek to promote safety adaptations, proposing improvements and implementations in accordance with current regulations.
