In the Black: Clearing the Air about Coal Dust

In the Black: Clearing the Air about Coal Dust

 · It was my day to take dust samples, the airquality tests that were mandated by minesafety rules. These rules required mines to measure the amount of coaldust in the air we were breathing. They were supposed to help protect us from contracting black lung disease. This was not my first go round of dust samples, and this would not be my last.

The dust particle diameters were small and the coal dust contained a high percentage of carbon, thereby giving a worstcase condition for nonanthracite coal mines. Results for the DPM Cassette were essentially identical to those obtained by the BOM impactors in a previous study. At a respirable coal dust concentration of mg m −3, which ...

 · In the first period of sampling, we had no information on the exposure of the coal miners. Thus, dust samples were alloed into different groups of workers using the method described by Leidel et al., (1977) as a guideline. A total of 110 filter cassettes for respirable dust were available for dust sampling.

Since 1972, MSHA regulations have provided that mine operators use the MSHA and NIOSHapproved coal mine dust personal sampler unit (CMDPSU) to sample mines to determine compliance with the MSHA coal dust exposure limit of 2 mg/m3. The current CMDPSU samples dust collected over an eighthour shift on cassettes.

SAMPLING DUST

SAMPLING DUST

RESPIRABLE DUST SAMPLING. When respirable dust (50% cut point of 4 microns) is being evaluated, you will need to use a cyclone. This is a sampling device that excludes dust particles larger than the respirable size. Depending on the type of cyclone used, a twoor threepiece cassette may be needed, so make sure you cheque before ordering.
