Abstract

The safety of work is of great importance for all industrial activities. The lack of actions that intend to decrease the work accidents makes the employees to remove themselves from their activities, increasing the production cost. The Brazilian legislation, by means of Regulatory Standard NR-15 (BRASIL, 2008), demands adaptation of the work environment to the employees, minimizing risks of biological, ergonomical, physical and chemical accidents. The aim of this work was to evaluate the organizational structure and the physical parameters noise, iluminance and temperature of work environment in furniture industries. The research was conducted in 14 furniture industries located at South of Minas Gerais State. In the evaluation of the organizational structure, a questionnaire and a collection of digital images were made, assuring the anonymity of the interviewed people. Measurings of noise was made by decibelimeter and dosimeter, while measurings of iluminance and temperature were made by, luximeter and digital globe thermometer, respectively. The results showed that the structure of the furniture industries is complex and confuse. The noise values ranged from 66.0 to 117.4 dB (A), in most of the cases, superior than that demanded by NR-15. The illuminance ranged from 8 to 7880 Lux, presenting high oscillations depending on the work post. The thermal charge that the employees are submitted to varied from 11.4 to 23.9, inferior than those demanded by NR-15.
