How to find the major dust sources.
Handbook for dust control in mining. Pittsburgh, PA: National Institute for Occupational Safety and Health, 2003 Jun; :109-117
In this chapter: instruments for measuring dust; how to calculate the amount of dust from a source; how to get a valid concentration measurement; sampling to assess control technology effectivenss. When there is more than one source of dust, sampling may be required to find which dust sources are most significant. Then, efforts to reduce dust can be concentrated where they will have the most impact. This chapter explains how to perform dust source sampling. It describes two kinds of instruments that are available and discusses their limitations. It explains how environmental variables such as concentration gradients, dust dilution, and production changes can impact dust measurements. It also suggests practical ways to improve the validity of dust source measurements under adverse conditions, such as high-velocity airflow or the presence of water mist in the air.
