Abstract

The Norma Regulamentadora (NR) 12 is one of the main regulations of the Ministério do Trabalho e Emprego, establishing guidelines to ensure safety in machinery and equip ment. Considering this context, especially in educational laboratories, this work aims to develop a project to adapt the manufacturing processes laboratory of the Instituto Fe deral de Educação, Ciência e Tecnologia da Bahia - Jequié, in accordance with NR 12, with the purpose of ensuring the safety of all individuals involved in that environment. To achieve this goal, it was necessary to conduct an in-depth bibliographic review of NR 12. Subsequently, the laboratory in question was inspected to identify all machines and equipment that fall under the aforementioned standard. Next, the NR 12 checklist was applied to assess the irregularities present in the laboratory. To assess the risks of machi nery and equipment, the Hazard Rating Number and risk categorization methods of NBR 12100:2013 were used. Finally, based on the results obtained from the checklist and risk assessment, corrective actions were proposed to bring the laboratory into compliance. It was found that the laboratory has a non-compliance rate of 61% with NR 12. All machi nes and equipment exhibited some form of irregularity, as well as significant safety risks to laboratory users. Among the main adaptations, it is recommended to provide NR 12 training before laboratory classes, make technical manuals available to users, and imple ment safety devices on machines, such as fixed, mobile, and start, stop, and emergency controls.
