Silica dust

2021-2-25Silica 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.

Method for Determining Crystalline Silica in Bulk

In 1970, the gravimetric respirable dust standard still required percentage crystalline silica in the sample for use in the denominator of the TLV formulae, which for respirable dust was 10 mg/m 3 /(% repirable quartz + 2) and for total dust was 30 mg/m 3 /(% quartz + 3). With the adoption of the gravimetric dust standards and respirable
