||Metal and non-metal miners' exposure to crystalline silica, 1998-2002
||2006, Vol.49, p.523-534. Illus. 42 ref.
||Crystalline silica is a well-known of cause silicosis and other diseases. Exposure is common in the mining industry and consequently, the U.S. Mine Safety and Health Administration (MSHA) regularly evaluates miners' exposure to silica to determine compliance with its exposure limit. MSHA exposure measurements were obtained for over 4000 mines between 1998 and 2002, and average exposure was calculated and classified by occupation and by mine. Evaluation criteria included whether average values exceeded MSHA's permissible exposure limit or the limit recommended by the National Institute for Occupational Safety and Health (NIOSH), whether there was a risk of exposure to freshly fractured silica, and whether there was a risk of a high rate of exposure to silica. It was found that miners in certain jobs are exposed to silica above permissible and recommended exposure limits. Some miners may also be exposed to freshly fractured silica.
