Occupational exposure limits are known to have different distribution values around the world. In recent years occupational exposure limits were reviewed in Lithuania and other Eastern European countries. The changes in occupational exposure limits should influence the hood flow rate. However even today the projectors continue using the same air flow rate equations that were developed years ago. The engineering methods are no longer compatible with sanitary standards. The major dangers resulting from this approach are the occupational exposure limits exceed allowed quotas in workplace or the energy consumption is harmfully inefficient. It is crucial to compare the treatment of occupational exposure limits among various countries and the different existing methods of calculating exhaust air flow rate. Additionally, it is important to consider the factors that may compromise the reliability of this study. Lithuania's occupational exposure limits are in general lower than in other countries. The ratio of occupational exposure limits is about 1:100 in different countries.Exhaust air flow should be inversely proportional to occupational exposure limits. It was found that volumetric exhaust flow rate have a circular dependence on occupational exposure limits by making comparison among different countries. The purpose of this study is to draw attention to the issue of small countries to use the volumetric exhaust air flow rate equations of big countries (USA, Russia, Germany etc.)... [to full text]
