Abstract
Este estudo teve como objetivo avaliar os níveis de ruído e vibração na atividade de coveamento semimecanizado em região montanhosa. Os dados foram coletados em duas áreas de cultivo de eucalipto situadas nas seguintes coordenadas geográficas: longitude 43º10’04.57”, latitude 18º 30’ 58.25’’, altitude 993 m e longitude 42º 54’ 17”, latitude 18º 52’ 33” e altitude 1012 respectivamente. Para avaliação do nível de ruído foi utilizado um decibelímetro e para análise da vibração um maestro da marca 01 DB. Os resultados evidenciaram que o motocoveador semimecanizado gera um nível de pressão sonora de 99 dB(A) e a vibração que o trabalhador florestal esta exposto é equivalente a 6,98m/s². Ao término deste estudo pode-se concluir que os níveis de ruído e vibração transmitidos aos trabalhadores florestais durante a realização da atividade de coveamento semimecanizado são superiores aos recomendados, podendo causar danos à saúde do trabalhador.
The study was done to assess the noise and vibration levels during semi-mechanized pit digging in mountainous region. The data were collected in two areas of eucalyptus cultivation located at longitude 43 o 10’04 .57 “W, latitude 18 o 30 ‘58.25’’S, altitude 993m, and longitude 42 ° 54’ 17”W, latitude 18 o 52 ‘33 “S and altitude 1012 m respectively. A decibel meter was used to measure the noise level and the analysis of vibration was done with the use of a mast model 01 DB. The results showed that the semi-mechanized pit digging generates 99 dB (A) and the forest laborer is exposed to vibration level of 6.98 m / s 2. it can be conclude that exposure of forest laborers to noise and vibration levels during semi-mechanized pit digging are higher than recommended, and can cause damage to their health.
