Avaliação dos parâmetros ocupacionais de risco: ruído, vibrações, poeiras e gases: indústria de Cimentos

Abstract

The study of the relationship between workers' health and their work requires the correct identification of occupational risk parameters and the consequences to which these individuals are exposed. This work has as objective the evaluations of parameters found in a cement factory making the identification of the risks that workers are exposed during their that workers are exposed during their activities found in this industry. A methodology used for the elaboration of this work was the bibliographical research, field work field work and analysis of the collected data. The parameters analysed were noise, vibrations dust and gases. The measurements were made during the period of activity in places with greater susceptibility of workers to exposure to these parameters. The noise results results showed that the raw materials classification sector presents the highest measured 88.3 dB, which does not allow workers to stay in this place for more than 4 hours, followed by the bagging sector. followed by the bagging sector with 85.4 dB which allows the worker to be active for 8 hours a day. activity during the 8 hours of daily work. The vibrations were measured in the two known known systems, hand-arm and whole body and the results showed that in the system of localised vibrations localised vibrations (hand-arm) the workers receive the highest doses of vibration, exceeding in some of the locations at 100%, where they received vibration doses of approximately 6 m/s2 being that the maximum limit allowed is 5 m/s 2 for this system. The results of the dust measured showed that the cement industry causes the excessive emission of dust which compromises the health and safety of workers directly exposed to this as well as the other workers in the factory. The results of the gases of the gases evaluated were generally satisfactory, with values well below the standards standards established for both CO and CO 2 . The factory's risk assessment allowed us to the risk factors and risks to which the workers are exposed in their activities, including the activities including the remaining known risk parameters and some measures that can be taken to help control exposure and improve the working environment it was recommended that factory workers be made aware of the hazards, their consequences and how to protect themselves from them, periodic evaluation of working conditions and a study of the other risk parameters that can be found in the factory.
