Aplicação da NR-12 - segurança de máquinas e equipamentos - em um laboratório de madeira em uma instituição de ensino profissional no Paraná

Abstract

The Paraná has the largest training institutions in Brazil. It offers various courses and technical education in the industrial area . Many of these courses have laboratories that pose risks to students, because the danger of machines and equipment . The regulatory norm n ° 12 , proposes measures prevencionistas safety and hygiene to be adopted by companies in relation to the installation , operation and maintenance of machines and equipment for the prevention of occupational accidents . The objective of this research was to apply NR - 12 in the identification of occupational hazards of machinery and equipment of a laboratory timber of an institution of vocational education. The survey was conducted from a case study in the application of NR - 12 in the laboratory timber of an institution of vocational education in Guarapuava - PR . The population studied was three machines , as follows: a circular saw , a saw and a router esquadrejadeira . Data collection was performed from a visit to the laboratory of the wood of the educational institution . On this visit there was the risk assessment of the three machines . In the evaluation created a risk matrix , with the lifting of the hazards and risks associated with each machine , severity and probability of the same . The three machines were evaluated, results of medium-risk to high in the categories of probability and severity of risk for accidents. Few operations performed by these machines showed low degree of risk . Given the results of the risk assessment of the machines , it was suggested possible control measures , based in the NR - 12 that can be used to minimize or even prevent certain accidents . From this work we can see that the institution of vocational education , even with all the technical apparatus , good people , still have some irregularities in the installation and operation of the machines , which may directly jeopardize the health of students and teachers working in the laboratory of timber.
