OSHA takes action to reduce miners’ exposure to silica dust as work continues on an improved health standard
The U.S. Department of Labor’s Mine Safety and Health Administration has launched a new enforcement initiative to better protect the nation’s miners from health hazards resulting from repeated overexposure to respirable crystalline silica. MSHA reports silica dust affects thousands of miners each year and, without adequate protection, miners face risks of serious illnesses, many of which can be fatal.
Crystalline silica is a common mineral found in the earth’s crust. Materials like sand, stone, concrete and mortar contain crystalline silica. Respirable crystalline silica – minute particles at least 100 times smaller than ordinary beach sand – becomes airborne during cutting, sawing, grinding, drilling, and crushing stone and rock.
