Estudo de caso: análise dos níveis de ruído, iluminância e utilização de equipamentos de proteção individual em uma oficina mecânica de automóveis

Abstract

In mechanical car workshops, most activities generate risks to employees, therefore, the present study aims to evaluate some of the factors that result in these risks, which are: the noise levels which the employee is exposed to, lighting in the local area where activities are developed and finally conducting a survey of Personal Protective Equipment (PPE) which are used by the employee and that exist on the property. This study was performed in a mechanical shop of small cars, located in the capital of Paraná, Curitiba. The work was carried out by just one mechanic. The workshop has only two employees who perform the same functions as they are exposed to the same risks. In order to carry out the assessment of noise levels which the employee is exposed to, there were three (3) dosimetry tests in sequential days, in which the resulting values were found below the action level (80 dB (A)) or between the action level (80 dB (A)) and the tolerance limit (85 dB (A)) according to NR-15, for an exhibition of 8 hours. Yet, there were also three (3) point measurements related to the screwdriver, welding and emery, equipment used by the official during three (3) days of measurement, which two met above the tolerance limit (85 dB (A) ), The screwdriver (95.6 dB (A)) and Emery (91.4 dB (A)). We also conducted measurements of illuminance in seven (7) points (points at which the employee performed his activities in the three (3) days of visit), in which three (3) of them were in places where all the equipment were placed and 4 points resulted in lighting failure. Finally, a survey of the existing PPE in the workshop and also those used by the employee was carried out and therefore it was possible to note that the mechanic takes risks of hearing loss, accidents and even contamination by using the other equipment without personal protection and in poor condition.
