Miners demand a new silica standard from MSHA

An alarming increase in the incidence of the black lung disease among the nation’s coal miners has led to a call by the United Mine Workers of America (UMWA) and the United Steelworkers International Union (USW) for a new standard to protect miners from the silica dust that causes the disease.

In a letter to David Zatezalo, the head of the Mine Safety and Health Administration (MSHA), UMWA President Cecil Roberts and USW President Leo W. Gerard noted that changes in mining practices have led to increased exposure to silica for miners.
