The illumination has a great influence on the performance of the students influencing their learning. Thus, this work has as main objective to evaluate the levels of illuminance that the users are submitted in the reading areas of the central library of the Federal University. For this, a luximeter was used and with the support of R software, statistical tests were performed to evaluate the behavior of the variable illuminance between the shifts, days and reading areas. It was observed that, in general, the library is not in compliance with the current norm, and there was no significant change in the average level of illumination between the shifts and days of measurement, except for the reading areas chosen for analysis. Therefore, it is advisable to maintain the electrical installations of this library, besides the placement of more luminaires near the windows and replacement of the lamps with the LED ones.

Abstract-The precast industry having activities that require great physical effort of workers, given that an increasing growth in the use of these constructions in components. Thus, the sector must have continuous monitoring of their activities, in order to seek interventions that aim to ensure a healthy work environment. With the intention to offer a healthy environment for workers, this study adopted the Ergonomic Work Analysis (EWA) as ergonomic diagnostic method to evaluate the working conditions imposed on workers of a precast industry located in the city of Teresina-PI. Was used two checklists established in the literature (OWAS and RULA) for the analysis with a sample of the population of workers who come each production sector in order to identify the postures taken by employees during the performance of work activities and their consequent discomforts and risks of developing diseases related to work. From the analysis there were many postural constraints made by workers and various areas of discomfort in the body, as well as poor conditions related to physical/environmental, generating disease development risks related to work. Finally, some recommendations were made in order to neutralize the bad working conditions identified.Index Terms-Ergonomic work analysis, OWAS, precast industry, RULA.
