Evaluation of the SKC® DPM cassette for monitoring diesel particulate matter in coal minest
In a previous study, the efficacy of commercial and prototype impactors for sampling diesel particulate matter (DPM) in coal mines was investigated. Laboratory and field samples were collected on quartz-fiber filters and analyzed for organic and elemental carbon. Coal dust contributed a minimal amount of elemental carbon when commercial cascade impactors and prototype impactors, designed by the...

متن کاملField measurement of diesel particulate matter emissions.
A primary means to reduce environmental levels of diesel particulate matter (DPM) exposure to miners is to reduce the amount of DPM emission from the engine. A quick and economic method to estimate engine particulate emission levels has been developed. The method relies on the measurement of pressure increase across a filter element that is briefly used to collect a DPM sample directly from the...
متن کاملMetal and Nonmetal Diesel Particulate Matter (DPM) Standard Error Factors for 350 μg/m Total Carbon Exposure Limit
As with all other exposure-based M/NM compliance determinations, MSHA will address uncontrollable sampling and analytical errors (SAE) by allowing a margin of error before issuing a citation for exceeding the total carbon (TC) limit. In addition to using the sum of organic carbon (OC) and elemental carbon (EC) as a measure of total carbon (i.e. TC(OC+EC)) MSHA will employ an enforcement policy ...
