Estudo dos principais fatores associados aos acidentes de trabalho em uma empresa de grande porte do ramo metal mecânico

Abstract

The aim of this study was to determine the factors associated to occupational accidents that occurred in a metal mechanic industry which operates in the automotive, highway construction, agricultural and construction businesses as well as auto parts manufacturing and in association with printing, machining, welding and surface treatment sets. To do so, a descriptive statistics analysis and an analytical approach were carried out, through the adjustment of a multivariable logistic regression model, considering both employees who had suffered accidents and those who had not. Initially, a conceptual model of approach for this study was synthesized and an exploratory research was developed, one which was composed of a data collection step and a case study step. In the data collection, the internal data of the organization being studied were used, in the case study step, relevant factors were estimated and identified and the ones which have the greater influence on occupational accidents. The following covariates were tested in the model: the functions executed, company time, work shift, age and sex. Among the covariates tested, the following showed statistically significant: executed function, age and employees sex, what suggests that a welder or a production assistant, aged up to twenty six years old and male has greater probability to suffer as occupational accident. Besides, a descriptive analysis was carried out referring to the medical certificates and comparisons between the records of injured employees, showing other factors such as the lesion place, the day of the week and the time that most accidents occurred. Generally speaking, it was possible to conclude that a male welder, with up to two years of company time, working the night shift and aged up to twenty six years old is more likely to have a lesion on the fingers, on Wednesdays, between 6pm and 8pm. It is believed that the results obtained in this research may contribute to broaden the knowledge about the factors associated to occupational accidents in the company being studied, providing subsides to the managers, in order to base their decisions to mitigate the number of occupational accidents.
