The cutting, breaking, crushing, drilling, grinding, or abrasive blasting of these materials may produce fine to ultra fine airborne silica dust. Silica occurs in three forms: crystalline, microcrystalline (or cryptocrystalline) and amorphous (non-crystalline). "Free" silica is composed of pure silicon dioxide, not combined with other elements ...
A hundred times smaller than a grain of sand, silica dust can lead to lung cancer and silicosis, an irreversible scarring and stiffening of the lungs, among other conditions, according to the ...
Silicosis, a disease caused by silica dust produced when workers cut and grind engineered stone, is afflicting workers. What consumers can do about it.
Researchers estimated that 100,000 workers in the U.S. are potentially at risk of silicosis due to exposure to silica dust. ... It is time for urgent action to stop these dangerous working ...
During various mining processes in which rock/minerals are broken up and collected for processing, mineral dusts are created and become airborne. Inhalation of these dusts can lead to various respiratory illnesses, depending on the dust type (e.g. coal, silica, etc.), size of the dust particulates, and exposure duration. [4]
The increased drilling generates deadly silica dust and has caused severe forms of pneumoconiosis, better known as black lung disease, even among younger miners, some in their 30s and 40s. “It is unconscionable that our nation’s miners have worked without adequate protection from silica dust despite it being a known health hazard for ...
Pneumoconiosis is the general term for a class of interstitial lung disease where inhalation of dust (for example, ash dust, lead particles, pollen grains etc) has caused interstitial fibrosis. [ 1 ] [ 2 ] The three most common types are asbestosis , silicosis , and coal miner's lung . [ 3 ]
On a national level, the Occupational Safety and Health Administration already requires fabrication shops to use “dust controls” to limit workers’ exposure to silica dust, such as saws with ...
