Thus, violating MSHAs silica limit alone but not its coal dust limit, does not result in a citation or fine to deter future violations. A separate standard for silica would allow MSHA to issue citations and monetary penalties for violating its silica limit to better protect miners from this toxic mineral.Dec 11, 2012 respirable and inhalable dust HSE Information about health and 18 The performance of the various respirable dust sampling methods recommended in this MDHS has been used sampling equipment to a clean, dust-free area such More detailedRespirable crystalline silica particles are particles that are smaller than 10 microns in size, enabling these particles to reach deep into the human lungs. Workers exposed to respirable crystalline silica can experience serious disease and ill health as the result of breathing in respirable crystalline silica dust.
