Silica -- also called silica dioxide or quartz dust -- is a naturally occurring substance found in dirt, sand, quartz, granite, clays, and other stones. Tiny particles of dust can be released into the air through the cutting, grinding, or drilling of rocks or products containing silica.
Silica dust is harmful when inhaled into your lungs. As it is 100 times smaller than a grain of sand, you can be breathing it in without knowing. Exposure to silica dust can lead to the development of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease and chronic obstructive pulmonary disease.
The potential air pollutants of most concern from frac sand mining are airborne particles, including particles less than 10 microns in size (PM 10), particles less than 2.5 microns in size ("fine particles" or PM 2.5), and crystalline silica, which ranges across both size categories.
The chronic silicosis caused by silica exposure poses unique dangers for employees working at frac sand mining sites. Because long-term exposure can be fatal, the Labor Department's Occupational Safety and Health Administration (OSHA) issued draft regulations designed to reduce the health risk and previously issued a hazard alert .
In summary, Monarch Silica intends to remain a good neighbor and a part of the community. We do recognize that our operations cause concern to some people and those concerns are important to us.
Frac Sand Mining or Silica Sand Mining. The potential air pollutants of most concern from frac sand mining are airborne particles, including particles less than 10 microns in size (PM10), particles less than 2.5 microns in size (typically called "fine particles" or PM2.5), and crystalline silica, which ranges across both size categories.
