Análise dos níveis de ruído, temperatura e segurança em máquinas no processo de injeção de uma empresa do ramo automotivo

Abstract

Increasing industrialization and automation of large factories, and technological advances have contributed to the emergence of many occupational health problems and accidents, resulting from exposure to risk agents and lack of safety in machinery and equipment. The proposed work aims to analyze the safety conditions of the machines, and noise levels and temperature of the jobs of the injection of an automotive industry. The levels of unhealthy agents were compared with the tolerance limits established in NR 15. The data collection for identification of safety conditions of machinery and equipment was performed by checklist based on protection and prevention measures adopted in the NR 12. Each of the requirements discussed was analyzed according to the current legislation, and the results obtained, it was possible to recommending improvements and solutions related to health and safety officials. For the attenuation of noise levels above the limit of 85 dB (A), the use of appropriate hearing protection is satisfactory. The temperatures of the jobs meet the tolerance limit of 26.7 ° C, being recommended to perform new measurements at different times of the year. As for the security requirements of machinery and equipment, the sector presents nine injection non conformities, which for appropriateness, need investment, training and accident prevention programs.
