Análise da relação entre sensação térmica e qualidade de vida no trabalho

Abstract

The aim of this study was to evaluate the relationship between thermal sensation and Quality of Work Life (QWL) in industries with different environmental characteristics. Data collection was done in three industries in the city of Ponta Grossa, Paraná State, each with different environmental characteristics of temperatures, namely a meat packing industry at low temperatures, a textile industry with neutral temperatures and metal industry with higher temperatures. To obtain data on environmental features such as air temperature, globe temperature, air velocity and relative humidity, used the station obtaining environmental data in 31 service stations by industry, the Predicted Mean Vote (PMV) calculated with data from environmental characteristics along with the dress and activities of workers. Questionnaires QVT Walton, adapted by Timossi (2009) were distributed. Of which 211 were completed, these 83 or 39.34% of the meatpacking industry, 73 or 34.60% of the textile, and 55 or 26.06% of the metal. Questionnaire was used only the criterion 'working conditions', to make the correlation between workers leased at their posts and the environmental characteristics of each post. It was observed that industries with extreme temperatures exhibited lower levels of QWL. In the textile industry, with neutral temperatures, QVT has averaged 72.60 (± 10.67), but to apply the correlation was found very low coefficient of determination, 0.029. The resulting mathematical equation, does not allow to find a variable from another. It is concluded that the relationship between thermal sensation through Predicted percentage dissatisfied (PPD) with QVT within the discretion of 'working conditions' has negligible values and establishes a correlation between the variables.
