The Occupational Safety and Health Administration (OSHA) has recently finalized a rule that would reduce the amount of respirable crystalline silica workers can be exposed to during an eight hour day. The rule, which would cut the permissible exposure limit (PEL) in half, will have broad implications for industries that use industrial sand, including hydraulic fracturing, glass making, foundries, and the construction industry.
In this episode of The Heartland Daily Podcast, Mark Ellis, the President of the National Industrial Sand Association and National Industrial Minerals Association of North America, and Isaac Orr discuss the specific changes being made to the current silica rules, and why the new changes may not be necessary in order to prevent new cases of silicosis, a serious but entirely preventable lung disease.
