Noise, vibration and general dust content in work place of mining, power plant and construction sectors, its hygienic assessment / Монголын Анагаах Ухаан

ABSTRACT

BACKGROUND: Nowadays, in economy of Mongolia there are a lot of mining, construction, transportation and powerplant sectors with high risk, top rate of industrial accidents and occupational disease. Moreover, it’sbeen seen that noise, vibration and dust effect on worker’s health have a huge negative effects inthose sector’s workplaces.GOAL Based on occupational condition assessment between 2010-2014 of Occupational condition andmonitoring department of Occupational Health Research Center, noise, vibration and general dustwere measured at workplace of mining, construction and power plant sectors.MATERIAL AND METHODS: Some issues of occupational hygiene were cross sectional studies. Based on archive of OHRC,information has been collected by fact methods. The results have been processed statistically onSPSS-17 statistic program and have been compared with relevant standards and normative.RESULTS: From 740 workplaces at 89 enterprises in 3 sectors, in 686 noises level has been measured. Theaverage level of noise measurements has been above the maximum allowed amount standards. Thehighest results were in sector of mining and construction.At total of 166 workplaces, the average vibration level was also above of maximum allowed amount.And also the highest results were seen in sector of mining.At total of 447 workplaces, the average general dust level was 3-5 times more than maximum allowedamount and the highest results were seen I sector of mining and construction.From some measurements of occupational hygiene at workplaces that attended in this study, generaldust amounts and vibration levels are straight low related and have a statistical importance.CONCLUTIONSThe amount of general vibration, noise and general dust in this research at sectors of construction,mining and power plant were higher than the standard of allowed amounts.
