Proposta de adequação de máquinas à norma regulamentadora nº 12 em uma indústria cerâmica localizada em Russas-CE

Abstract

The adaptation of machines to Regulatory Standard nº 12 is essential to ensure workers' safety and the legal compliance of industries. In the ceramic sector, the use of machines such as vacuum extruders and clay mixers increases the risk of accidents, making the implementation of protective measures indispensable. This study aimed to evaluate and select safety systems for these machines, proposing solutions for compliance with NR-12. The research was conducted through a case study in a ceramic industry located in Russas-CE. The methodology involved a risk assessment according to NBR ISO 12100, the application of the Hazard Rating Number (HRN) tool and safety categorization according to NBR 14153. The results showed that several areas of the machines presented high risks, mainly due to the lack of adequate physical protections, such as the belt transmission system of the extruder and the mixer. As a solution, safety measures were proposed, including fixed guards, safety devices and proper signaling, aiming to reduce risks to acceptable levels. The application of HRN demonstrated that implementing the proposed measures could significantly reduce risks, making them acceptable according to regulatory criteria. The implementation of these adaptations will contribute to a safer work environment, reducing exposure to risks and ensuring compliance with current legislation.
