Mechanical intervention for reducing dust concentration in traditional rice mills
A huge number of workers are employed in traditional rice mills where they are potentially exposed to dust. In this study a dust collection system was developed to capture the airborne dust in the rice mill. The feeding and sieving section of the mill was identified as major dust creating zone. The dust was captured by creating suitable air stream at feeding and sieving sections of the mill and...
متن کاملDust and flour aeroallergen exposure in flour mills and bakeries.
As part of an epidemiological study among workers exposed to flour total dust and flour aeroallergen concentrations were measured with personal samplers over a workshift in three large bakeries and four flour mills and packing stations. In the bakeries geometric means for total dust concentrations ranged from 0.4 mg/m3 in the bread wrapping area up to 6.4 mg/m3 at the dough brake. The flour aer...

Ascertainment The ascertainment rate of defectives reported to Local Authorities was?at the beginning of 1937?2.88 per 1,000 of the population. (It will be remembered that the estimate given by the Wood Committee, of defectives for whom Local Authorities are, or may at anv time become, responsible was 4.52 per 1,000.) To the usual table giving the ascertainment rate of each individual Local Aut...
