D. Total Dust Sampling Train . Total dust sampling uses the same type of filter cassette required for respirable dust sampling. Assemble the apparatus with Orings placed on the top and bottom of the cassette to seat the cassette snugly in the cassette holder (refer to Figure 54), or use the top of the metal cyclone holder seated into the cassette
Coal Dust Sampling Cassettes – Zefon International – ..

The DPM Cassette Other cassettes may meet NIOSH Method 5040 specifications for the collection of diesel particulate, but only the SKC DPM Cassette separates diesel particulate matter (DPM) from other respirable dust (such as coal dust) based on particle size. The precisionjeweled impactor and impaction substrate, loaded into a streamlined ...
The final rule only addresses the approval of coal mine dust sampling devices. As stated previously, this rule does not address their particular use in coal mines. Therefore, the final rule does not affect coal mines, nor does it have a significant energy action that adversely affects energy supply, distribution, or .
Section (c)(5) requires that, when CPDMs are used for sampling, underground coal mine operators print, sign and post a paper record (Dust Data Card) with the shift length. Under section (c)(5), when CPDMs are used for sampling, coal mine operators must print, sign and provide to each part 90 miner a Dust Data Card with the shift length.

The DPM Cassette is designed for sampling in atmospheres where it is necessary to separate DPM from other respirable dust, such as coal dust. The single use cassettes are tamperevident sealed to ensure sample integrity. It provides optimum DPM collection efficiency, and has been evaluated at L/min in metal/nonmetal mines and 2 L/min in ...
While selection of a specific cassette size/type and filter membrane should be determined by review of the NIOSH sampling guide, the following rules generally apply:All dusts, fumes and powders sampling – use 37mm filter and asbestos and fibers sampling – use 25mm filter and sampling – use micron (pore size ...
Since isokinetic sampling is conventionally used to determine total dust concentration, and isokinetic sampling made a difference in collected masses, the results suggest when sampling for coarse coal dust the IOMMOD may improve airborne coarse dust assessments over "offtheshelf" sampling cassettes.
ABSTRACTAirborne coal dust generated during mining can deposit and accumulate on mine surfaces, presenting a dust explosion hazard. When assessing dust hazard mitigation strategies for airborne dust reduction, sampling is done in highvelocity ventilation air, which is used to purge the mining face and gallery tunnel. In this environment, the sampler inlet velocity should be matched to the air ...
Silica East Coast: Jason McDonald, John Passero, ext. 3604 West Coast: Randy Cavadini, The Occupational Safety and Health Administration (OSHA) issued a final rule to help protect workers from exposure to respirable crystalline silica, which is being phased into effect starting on June 23, 2016.
Mixtures of known coal and limestone dust masses were prepared in the laboratory, loaded into the stainless steel cassettes, and analyzed to assess the accuracy of this method. Coal dust mass measurements differed from predicted values by an average of %, %, and % for samples containing 20%, 91%, and 95% limestone dust, respectively.
A commercial version of the BOM impactor, called the DPM Cassette, was recently introduced by SKC[registered sign]. Tests were conducted to evaluate the performance of the DPM Cassette for measuring dieselsource elemental carbon in the presence of coal dust. Bituminous coals from three mines in two different coal provinces were examined.
The mass fractions of the total quartz sample on the internal cassette surface are significantly different between polystyrene and staticdissipative cassettes for all cyclones (p < ). No consistent relationship between quartz mass on cassette internal surface and coal dust filter mass was observed.
Since isokinetic sampling is conventionally used to determine total dust concentration, and isokinetic sampling made a difference in collected masses, the results suggest when sampling for coarse coal dust the IOMMOD may improve airborne coarse dust assessments over "offtheshelf" sampling cassettes.
SKC Diesel Particulate Matter Cassettes are designed for sampling in atmospheres where it is necessary to separate DPM from other respirable dust (such as coal dust). Singleuse SKC DPM Cassettes are tamperevident sealed to ensure sample integrity. Each streamlined plastic cassette comprises an impactor plate, impaction substrate, and two heat ...
