ANÁLISE ERGONÔMICA DO AMBIENTE DE TRABALHO NA FABRICAÇÃO DE FERRAMENTAS FLORESTAIS

Abstract

This research aimed to evaluate the work environment in a tool manufacturing factory. This process involves the cutting activities, orvado, turning, forger, temper, cable insertion, grinding, welding and varnishing. To evaluate the thermal comfort was used IBUTG to measure the wind speed anemometer, lux meter to evaluate the brightness and decibel meter to analyse the exposure of workers to noise. The data ranged IBUTG on average 20.9°C at 27.3°C. The forger had the highest IBUTG values averaged over the entire production process. All activities had wind speeds below 0.75 m/s, being perfectly acceptable for the entire workday. The average luminance oscillated from 42.9 lux to 393.3 lux. The activities of varnish, temper, forger and cable insertion had average illuminance below 150 lux required throughout the workday. All activities presented noise above 85 dB(A), except the varnishing and cutting. Noise levels ranged on average of 79.7 dB(A) in varnishing at 8 hours 95.7 dB (A), in the grinding at 13 hours.
