Agregar Etiqueta | Sumario: | Noise in the workplace causes negative effects on the health of workers, the objective of this research was to design an operational control on the incidence of noise levels in occupational morbidity, through a measurement study in the identified processes of higher risk in the GTC 45 in the metal-mechanic industry in Quevedo, the population distribution was determined in the 4 production sectors comprised of 70 processes and a population group of 65 people, the male sex prevailed with 89%, the age range between 31-40 years with 34%, the working time between 3-8 years with 35%, the risk perception of 46% is bearable with protection; It was determined through the noise study that 80% of the measurements presented critical and high risk levels, with 43% and 37% respectively, sector 2 being the most affected; while of the remaining 20%, 9% are part of medium risks, only 11% were low; 78% presented occupational hearing loss, a high percentage reported health changes related to noise; demonstrating the relationship between noise levels and occupational morbidity with a hypothesis test; expressed a value of Spearman's Rho in the production sectors of the industry in general of 0.6247428; The alternative hypothesis is accepted and the null hypothesis is rejected, demonstrating a moderate linear relationship between the variables under study in which noise does affect occupational morbidity in the metal-mechanic industry; Finally, the proposed collective and individual operational control was designed, which guarantees the reduction of noise according to its attenuation, at the source, medium and the worker with the technical specifications and attenuation levels that the manufacturers recommend for application. Keywords: Operational control, occupational hearing loss, noise. |
