El ruido y su incidencia en afecciones auditivas del personal operativo en el proceso de elaboración de balanceados de la empresa Bioalimentar Cia. Ltda

Abstract

EXECUTIVE SUMMARY The present research analyzes the problem of the presence of noise in the balanced development of the Company Bioalimentar Cia. Ltda. Being critical part for influencing hearing impairments in workers who are part of the production process. In the analysis of the study it evidenced the company has a s initial risk assessment methodology using the NTP 330, which allows qualitatively identify the risks in the jobs. The evaluation depends on the subjectivity of the technician. The matrix is evidence that there are levels of risk considered noise Altos para shares and should take immediate corrective action. FOR PROPER Analysis of Noise Levels in Jobs measurements was performed with sonometro Type 2. This Analysis Higher levels of 85 dB was determined in 50% of Jobs. Of the total of 12 monitoring conducted real and quantitative data of actual risk level is obtained. We also evaluated the permissible limits established in Decree 2393, obtaining a dose mayor is June 1 Jobs Representing 50% with High Risk, y2 Between 0.5 and 1 Representing 17% Medium Risk and Low Risk 4 jobs con un 33%. To analyze possible hearing impairments v Medical Evaluations With Conducting a audiometries All staff realize the production process. Medical evaluation In 9 cases with symptoms of early and advanced acoustic trauma is nine workers of a population of 84 characters with 10% resultado Workers Affected noise ratio was determined. This is determined and conditions are at the frequency of 4000 Hz What the Evidence Relationship with noise. The proposal to improve working conditions and avoid hearing impairments involves the development of a program of auditory control. For this implementation and physical suitability of the medical clinic company with technological equipment as audiometer audiometry booth covers . These are accompanied by procedures and records to take appropriate management in monitoring the health of workers . Because the sources of noise are machines that are part of the process of elaboration of balanced and that control can not initially give the source . For this, the implementation of procedures that allow the correct assessment of noise and adequacy of facilities, equipment , machinery, organizational processes , raw materials among others with implementation of process control management change adds .
