Evaluación de los niveles de ruido laboral en el área de rivera y lijas de la empresa Curtiduría Tungurahua S.A.

Abstract

Occupational noise in manufacturing processes is mainly generated by the presence of machinery, which can cause health problems for workers; therefore the objective of the research is to evaluate the levels of occupational noise in the area of rivera and sandpaper of the company Curtiduría Tungurahua S.A. The noise evaluation is based on the application of the NTE INEN - ISO 9612:2009 standard, for the phases of identification, definition and measurement; while for the proposal of noise control, the Executive Decree 2393 is used. The analysis phase, according to the application of the standard, shows that there is fluctuating noise at the sanding workstation generated by the turbine and impact noise at the fleshing workstation. This type of noise is caused by the mechanical and hydraulic activation of the machine, by the oscillation of the shaft that connects with the motor and the action of the blades. The results of the measurements show 90.79 dB(A) plus minus 4.3 and 79.59 dB(A) plus minus 3.8 respectively; values which, according to Executive Decree 2393, are above the permitted limit and require monitoring. The 7 workers in the sanding and fleshing workplaces are exposed to an intolerable level of noise, which can lead to health effects on their hearing.
