· Also, in both cases viz. stone mines and crushing unit, dust exposure for two (2) and three (3) samples respectively had exceeded the MEL and PLV values. Since a majority of the workers were exposed to high levels of dust containing free silica during the course of their work there is every possibility of serious health issues arising for the workers in the future.
The purpose of this study is to describe the personal exposure to respirable dust and quartz and in stone crushing units loed at west of Iran. A size of 40 personal samples and 40 stationary samples were obtained and analysis was done by Xray diffraction (XRD). The results of personal sampling w .
A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and subbases for road making.
based NGO, to investigate potential silica exposures among a cluster of 150 small stone crushing mills loed in the Khurda District in the Indian State of Orissa. The partners initiated a study on measures to reduce respirable crystalline silica exposures in smallscale mechanized stone crusher .
