Máquinas de colheita florestal: avaliação de segurança de acordo com o Anexo XI da NR-12

Abstract

This study aimed to develop a tool for evaluating and its application for the verification of work safety conditions in machines used in forest harvesting, in accordance with Annex XI of the RN12. A descriptive survey was carried out and a questionnaire based on a checklist was applied, which was a compilation of the applicable items of the referred standard. The checklist was applied on machines of a company specialized in harvesting and forest transportation that operates throughout the state of Minas Gerais. The verified results demonstrate the effectiveness of the use of the methodology proposed to identify the compliance of the reference standard items. An average percentage of 82% was found in compliance with the applicable items of said standard, indicating that nonconformities are still capable of contributing to the occurrence of occupational accidents and diseases; and that the great majority of the nonconforming items found are due to the intense operational requirement, the extreme working conditions and the useful life of some machines evaluated. It is concluded that the applied methodology was considered adequate because it allowed the verification of compliance of the labor safety standards in forest harvesting machines in a fast and efficient way, being easy to apply and presenting reliable results. Also, that the result of the evaluation is configured as worrying, since the observed nonconformities are capable of contributing to the occurrence of occupational accidents and to the emergence of occupational diseases.
