Abstract

SUMMARY: The objective is to assess the effects of the new technologies and the modernisation of the technological processes employed in the production of primary aluminium on the level of total noise workers are exposed to in the work environment. For this purpose the results of mandatory periodic measurements of physical factors at the work places in the factory Aluminij d.d. Mostar were compared, before the modernisation (1988) and after the modernisation (2004). The measurements of the total noise levels were made at the same work places. In the paper the measured total noise levels after the modernisation are compared with those before the modernisation in the factory plants Anode, Electrolysis, Foundry and Gas Processing. The results measured before the modernisation show excess noise at 68.9% work places. After the modernisation the number of the work places with excess noise was significantly reduced, by 28.6% (48/168), and the levels of noise were also lower. Best results were achieved in the plants Anode and Foundry, where the number of the work places with excess noise was reduced by more than a half. Noise remains the greatest problem in the Gas Processing plant where the noise level exceeds the recommended values, even after the modernisation, at more than half of the work places. Despite evident improvements in noise reduction after the factory modernisation and more sophisticated technological processes introduced, excess noise has not been removed.
