8. Example: A valid representative dust sample with an equivalent concentration of mg/m3. contains % of quartz dust corresponds to a quartz concentration of 138 mg/m3. . The respirable dust standard when quartz is present is maintained on each shift at or below mg/m3. (10/% = mg/m3. ). Back to Citation

Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction and oil gas sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials. The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles.

Mar 11, 2014· The key to prevention is keeping dust out of the air. Hazard alerts published in California and Washington State described exposure to silica dust and other hazards related to fabrication of granite and natural stone products and provided dust control recommendations. Whenever possible, cutting, grinding and shaping should be done wet.
Silica dust (crystalline silica) is found in some stone, rock, sand, gravel and clay. The most common form is quartz. Silica dust can also be found in the following products: bricks; tiles; concrete; some plastic material. When these materials are worked on, silica is released as a fine dust known as respirable crystalline silica or silica dust.
The percentage of quartz was calculated from the mass of quartz and the total gravimetrically determined respirable dust on the filter. Samples with quartz levels below µg ( n = 4) were set at twothirds of this value divided by the average sampling volume, which resulted in a limit of detection for quartz measurements of µg/m 3 .

The intent of this dust standard reduction is to restrict miners'' exposure to respirable quartz to a timeweighted average concentration of 100 microg/m3. The effectiveness of this indirect approach to control quartz exposure was evaluated by analyzing respirable dust samples collected by MSHA inspectors from 1995 through 2008.
It is easily wiped off but comes back quickly. For aquascapers that had tanks with chronic GDA, wiping the glass on a weekly basis might seem like an inevitable thing I assure you that it is not. Read on to find out how to control green dust algae (GDA) in a planted aquarium.

Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become respirable size particles when workers chip, cut, drill, or ...
Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust. It is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the is a type of pneumoconiosis. Silicosis (particularly the acute form) is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin). It may often be misdiagnosed as ...
