Estudo de qualidade de ar e ruído/factores ergonómicos nas indύstrias. Caso de estudo terminal de combustíveis porto da Matola

Abstract

The subject of this work is a study of Air Quality and Noise/Ergonomic Factors in Industries. Case study Fuel Terminal Terminal, and was based on the analysis and evaluation of air quality and noise in the workplace generated by fuel loading and unloading activities. Ergonomic assessment (air and noise) aims to improve the quality of health of the workers. to improve the quality of health to which employees are exposed. A quantitative analysis was made of the risks of exposure during their work tasks. tasks. The assessment of air quality and noise is carried out using parameters such as carbon monoxide, sulphur dioxide, particulate matter, etc. monoxide, sulphur dioxide, particulate matter, carbon dioxide, nitrogen dioxide and methane. methane, and noise was measured in dB. After determining the parameters, the results obtained were compared with the legally considered acceptable for work environments. Thus, the results obtained for particulate matter (dust) were above the limit stipulated as the highest value for the wagon loading crane. crane. The values range from 253mg/m³ to 1094mg/m³.For the other air quality parameters such as carbon monoxide, nitrogen dioxide, etc. nitrogen dioxide, the results were within the limit except for carbon dioxide and sulphur dioxide. dioxide and sulphur dioxide, which peaked at the truck loading crane and the wagon loading crane respectively. truck loading crane and wagon loading crane respectively. For noise levels, it was observed that the greatest propagation was in the sector of the fire pumps when switched on, measured at 120dB, thus representing a serious risk of exposure to employees. However, the aim is to importance to the health of employees and identify the need to implement measures to control and reduce the impacts. (TRADUÇAO NOSSA)
