Guidance about dusts and other airborne contaminants

One of the most common dusts encountered on mine sites is quartz crystalline silica which is a mineral found in many ore bodies In the past workers could develop silicosis but an understanding of how to minimise exposure has meant there have been no new cases of silicosis in miners solely employed in Western Australian mines for over 40 years.
